1/4″ HSS Tool Blank
Lathe tools—also known as tool bits—are the cutting tools used for turning, facing, and other operations on a lathe. The most commonly used are high-speed steel (HSS) tools, which are suitable for machining a wide range of materials including wood, plastic, aluminum, brass, and steel. HSS tools maintain their hardness at temperatures up to 1000°F (588°C), making proper depth of cut, cutting speed, and feed rate essential for optimal performance.
One of the key advantages of HSS tools is how easily they can be resharpened using a standard aluminum oxide grinding wheel. Once sharpened, they retain a keen cutting edge through extended use.
Each Sherline lathe comes with a pre-sharpened 1/4″ HSS cutting tool. Pre-ground tool sets—featuring right-hand, left-hand, and boring tools—are also available. However, for long-term savings and flexibility, learning to grind your own tools from blanks is recommended. Custom-shaped tools can be saved for repeat jobs or re-ground for new applications.

3C Step Collet
The 3C Step Collet features a 2″ diameter and 1″ depth, making it an excellent addition for machinists using the Sherline 3C headstock. It can be easily machined to size and is specifically designed to hold larger workpieces.
A 1/4″ (6.35 mm) dowel pin is included to provide a gripping surface during the boring process. This helps minimize runout and ensures greater accuracy in the finished bore. Once machined to the desired diameter and depth, the collet effectively becomes a custom chuck—ideal for parts too large for standard 3C collets.
Other head sizes may be available. Please contact Sherline for additional options and pricing.
NOTE: This step collet is designed to grip material only at the face end, not through the collet. Maximum gripping depth is approximately 3/4″ to 7/8″ (19.05 mm to 22.23 mm).
Contact us to inquire about other available step collet head sizes.

Carbide Insert LH 55° 3/8″ Boring Bar w/2 Flats
Sherline’s gang-tooling tool post (P/N 5930) was specifically designed for customers converting their Sherline lathe into a chucker-style or gang-tooling lathe. Since most parts produced on a chucker lathe are 1/2" (13 mm) in diameter or smaller, and the center-to-center spacing on our gang-tooling post is 1.5" (38 mm), we identified a practical opportunity: our boring bars can double as both boring and outside diameter (O.D.) turning tools.
To support this dual use, we modified our standard boring bars by adding a second locating flat. This allows them to be mounted with the insert face up or face down, providing flexibility for front- or back-side operations. For example, right-hand 80° and 55° boring bars can now be used effectively on either side of the part (see Figure 1).
These 3/8" diameter boring bars are designed to hold a 2-sided 55° carbide insert, secured with a Torx® screw. Each holder includes an 55° carbide insert and a Torx driver.
-
Each holder is 3-1/4" long and can bore to a depth of just over 2" when secured with two set screws.
-
Constructed from 1144 Stressproof® steel with a black oxide finish for strength and corrosion resistance.
See instructions below for additional guidance on using two-flat boring bars with gang tooling setups.
Pro Tip: Consider using the boring bar with the insert face down to help reduce chip buildup on the insert during cutting. This orientation can improve chip evacuation and extend insert life.
FIGURE 1—55° boring bars used as examples. The left-hand tools are used as turning tools, while the right-hand tools are used as boring tools.
Note: The straight-groove chip breaker shown in some older images is no longer available. Current inserts feature the spider web-style chip breaker as shown here

Interchangeable Jaws
Certain delicate parts require gripping with softer jaw materials. Other operations require chuck jaws that do not transmit particles of rust to the part being held. To accommodate these special circumstances, Sherline now offers 2-piece chuck jaws with interchangeable top jaws made from special materials, and bottom master jaws*. In place of the standard hardened or optional unhardened (“soft”) steel 1-piece jaws, these new top jaws are .600” tall and come in soft materials like Delrin, Teflon, and Nylon, plus harder but non-rusting materials like brass and aluminum. The replaceable top jaws are fastened to the hardened steel bottom jaws with two countersunk socket head screws. They are not stepped so the customer can machine them for custom holding applications. Other materials are available by request.
*Please note that you must purchase the bottom master jaws before you can use the top jaws.
Tall Top JawsWe also offer taller jaws with heights of 1” and 1-1/2”. The tall jaws are made of aluminum and mild steel. These taller jaws were developed for a customer who uses our lathe for custom jewelry design and can be machined to hold custom work, as seen in the photo to the right.
About Top-Jaw Custom Orders See the Top-Jaw Custom Orders tab below to design your own chuck jaws.NOTE: To customers who are buying these jaws for an existing chuck, please measure the width of your current chuck jaws with a pair of mics so we can grind your master jaws to match. State your current jaw width in the comments box below. For first-time buyers who are buying a new chuck with these Master jaws, your jaws will be ground to match your chuck.

Bump Knurl Tool Holder
Knurling Tool Holder
Sherline's knurling tool adds a professional touch to your parts by embossing knurls into the surface, rather than cutting them. Straight knurls are commonly used on the ends of shafts that will be pressed into other parts, while both straight and diamond knurl patterns are ideal for enhancing grip on handwheels and thumbscrews.
This tool can accommodate diameters up to 1" (25 mm) and features both right and left sides that evenly clamp down on your part as it's turned in the lathe, creating a consistent knurled pattern. It comes with one set of spiral knurls that form a diamond pattern.
Additional sizes of knurls for both diamond and straight patterns are also available in the addition knurls tab below.
Note: This knurling tool is not intended for use with riser blocks.
Quick-Change 3/8″ Square Shank Tool Holder
Quick-Change Carbide Insert Tool Holder
This holder is not included with the Quick-Change Tool Post System (P/N 2250) but is available separately for users who want to take advantage of the enhanced cutting performance offered by carbide tools. The holder includes one 55° carbide insert with two cutting edges, secured by a small screw. A Torx wrench for tightening the screw is also provided.
Like the Quick-Change Tool Post and other dovetailed holders in the system, this inserted tip holder is made from case-hardened steel with a black oxide finish for durability and corrosion resistance.
To learn more about the benefits of using inserted tip carbide tools, CLICK HERE to download a detailed PDF guide.
55° RH and LH Tool Holders w/Carbide Inserts
These tool holders are available individually in right-hand or left-hand configurations, or as a matched pair. Each holder includes a 55° carbide insert, a hold-down screw, and a Torx® key for installation. Designed with a 3/8" square shank, they fit standard 3/8" tool posts, and the insert tip is precisely 0.375" from the base of the holder—an industry-standard dimension.
The 5° offset angle of the cutting tip provides added versatility for certain operations. For example, when the holder is squared with the crosslide, it allows you to turn an outside diameter (O.D.) up to a shoulder and then finish the shoulder by backing the tool out—while maintaining proper tool clearance.
Constructed from case-hardened steel with a durable black oxide finish, these holders are built for long-lasting performance.
Although carbide insert tools are more costly than high-speed steel (HSS) tools, they offer an advantage: when the cutting edge becomes dull or chipped, you can simply rotate the insert 180° to use the second edge—essentially giving you two tools in one.
While HSS tools remain the primary choice for miniature machining due to their low cost, resharpenability, and adaptability for custom form tools, carbide insert tools are invaluable for specific applications. They maintain a sharp edge when cutting hard or abrasive materials, reduce tool wear, and allow for faster machining—reasons why they're widely used in professional machine shops.
Note: Tool orientation is named by the direction the chip exits the tool. A right-hand tool has its cutting edge on the left, and the chip peels off to the right.
Updated Note: The previously used straight-groove chip breaker insert shown in some images is no longer available. All current inserts now come with the spider web-style chip breaker as shown here.
80° RH and LH Tool Holders w/Carbide Inserts
These holders are available individually in right-hand and left-hand configurations, or as a matched pair. Each includes an 80° carbide insert, a hold-down screw, and a Torx® key for installation.
Specifications & Features:
-
3/8" square shank, compatible with standard 3/8" insert tool posts
-
5° offset angle provides better tool clearance for complex operations
-
Tip height is 0.375" from the base, meeting industry standards
-
Constructed from case-hardened steel with a durable black oxide finish
-
80° inserts are ideal for roughing cuts
-
55° insert holders are also available for sharper corner access
For example, when the holder is squared with the crosslide, it allows you to turn an O.D. up to a shoulder, then finish the shoulder by backing the tool out—while maintaining proper clearance throughout the cut.
Advantages of Inserted Tip Carbide Tools
Although more expensive than high-speed steel (HSS), carbide inserts offer key benefits:
-
Each insert can be rotated 180°, giving you two cutting edges per insert
-
Maintain a sharp edge when cutting exotic alloys or abrasive materials
-
Enable faster cutting speeds and improved surface finishes
While HSS tools are ideal for general use due to their affordability and ease of resharpening, carbide tools are essential for challenging jobs, which is why they're widely used in professional machine shops.
Note: Tool orientation is based on the direction of chip flow. A right-hand tool has its cutting edge on the left, with chips exiting to the right.
Chip Breaker Update: The previously used straight-groove chip breaker is no longer available. Current inserts now come with the improved spider web-style chip breaker, as shown in the updated product images.
RH 55° and 80° 3/8″ Boring Bars w/Carbide Inserts
These 3/8" diameter boring bars feature a carbide insert secured with a Torx® screw and come complete with a Torx wrench. Choose between:
-
A 55° right-hand insert, suitable for starting holes as small as 3/4", ideal for reaching sharp internal corners
-
An 80° insert, which fits into a smaller 1/2" hole and offers added strength for roughing operations
Each holder measures 3-1/4" long and can bore to a depth of just over 2" when properly secured with two set screws. Manufactured from durable 1144 Stressproof® steel with a black oxide finish, these tools are available individually or as a discounted set.
Why Choose Carbide Insert Tools?
While high-speed steel (HSS) remains common for small machine tools due to its low cost and resharpenability, carbide inserts offer significant advantages in demanding applications:
-
Longer-lasting edges when cutting hard metals like stainless steel, titanium, or abrasive materials such as carbon fiber
-
Faster cutting speeds and greater efficiency
-
Each insert can be rotated 180°, effectively giving you two cutting edges per insert
Although carbide inserts can't be resharpened, their durability and versatility make them a preferred choice in professional machine shops.
Note: The older straight-groove chip breaker insert is no longer available. Current inserts include the spider web-style chip breaker, as shown in the updated images here & here
LH 55° & 80° 3/8″ Boring Bars w/Carbide Inserts
These 3/8" diameter boring bars hold a carbide insert secured with a Torx screw. Each comes with either a 2-sided 55° or 80° carbide insert and Torx wrench. The 55° LH boring tool will fit into a 3/4" starting hole. The 80° holder will fit into a smaller 1/2" hole. The 80° holder offers a little more strength for roughing cuts while the 55° insert will cut into sharper corners. The 3-1/4" long holder can bore a hole a little over 2" deep with two fastening screws tightened on it. The holders are made from 1144 Stress-proof steel with a black oxide finish. Available individually.
Left Hand Boring Bars
These LH boring bars are not intended to be used for boring on a standard Sherline lathe, as the spindle is not reversible without electronic modifications. They were developed for a Sherline tool that is now in development where they will be used as a turning tool from the backside with the bit upside down. Watch for the introduction of this new “chucker” lathe soon.
Advantages of Using Carbide Insert Tools
Though relatively expensive, if a cutting edge of a carbide insert becomes dull or chipped, the insert can be removed and rotated 180° to expose two new cutting surfaces, providing, in effect, two tools for the price of one.
The primary method of cutting metal on miniature machine tools is usually with high-speed steel tools as they are inexpensive, easily resharpened and can be ground into "form" tools for special jobs. However, inserted tip carbide tools can be lifesavers for some jobs. Though more expensive and not able to be resharpened, carbide tools hold their cutting edge when cutting exotic metals like stainless steel or titanium or abrasive materials like carbon fiber and can speed up the cutting process. This is why they are used for most cutting tasks in the modern professional machine shop.
NOTE: A tool is named by the direction from which the chip leaves the tool; so a right-hand tool has its cutting edge on the left and the chip peels off to the right.

1/4″ HSS Tool Blank Set
Lathe tools—also known as tool bits—are the cutting tools used for turning, facing, and other operations on a lathe. The most commonly used are high-speed steel (HSS) tools, which are suitable for machining a wide range of materials including wood, plastic, aluminum, brass, and steel. HSS tools maintain their hardness at temperatures up to 1000°F (588°C), making proper depth of cut, cutting speed, and feed rate essential for optimal performance.
One of the key advantages of HSS tools is how easily they can be resharpened using a standard aluminum oxide grinding wheel. Once sharpened, they retain a keen cutting edge through extended use.
Each Sherline lathe comes with a pre-sharpened 1/4" HSS cutting tool. Pre-ground tool sets—featuring right-hand, left-hand, and boring tools—are also available. However, for long-term savings and flexibility, learning to grind your own tools from blanks is recommended. Custom-shaped tools can be saved for repeat jobs or re-ground for new applications.
Slitting Saws
Each saw blade is 2" in diameter with a 1/2" hole. The saw blades come in varying thicknesses and teeth counts. They require the slitting saw holder, which is held in the spindle with a drawbolt that pulls the holder up into the Morse #1 taper.
Note: Due to supply chain issues, the outside diameter of some of our saw blades may be 2-1/2" instead of 2" and teeth counts can vary. If you need a specific number of teeth in a certain size, please contact us to see if we have them in stock
55° Carbide Insert
While not inexpensive, carbide inserts offer excellent value—each insert provides four cutting edges, significantly reducing the need for frequent sharpening and saving valuable time.
Carbide cutters perform well on hard-to-machine materials like cold-rolled steel and are also effective on aluminum, brass, and leaded steels, offering exceptional durability. However, for the finest finishes on softer metals, a well-sharpened high-speed steel tool still delivers superior results.
This is the 10-pack of replacement carbide inserts for the following tool holders:

1/4″ 3-Flute End Mill Set
3-piece Center Drill Set
Center drills are essential for accurately drilling starter holes in the ends of workpieces, particularly when mounting stock between centers on a lathe. Each drill creates a small pilot hole followed by a 60° countersink, which provides a seating surface for the 60° point of the lathe center.
In milling applications, center drills are commonly used to start holes precisely. The exact hole location can be dialed in using the mill’s calibrated handwheels, and the center drill ensures the hole begins accurately without drifting.
This set includes three double-ended, high-speed steel (HSS) center drills:
-
#1 drill: 1/8" shank
-
#2 drill: 3/16" shank
-
#3 drill: 1/4" shank
The larger shank diameter of a center drill ensures the tip remains centered, reducing the risk of the drill "walking" as the hole is started. After the center drill has established the starter hole, it is replaced with a standard drill bit to complete the hole to the desired diameter.
⚠️ CAUTION: Always use a suitable cutting lubricant and back the drill out frequently during use. This prevents the delicate tip from overheating or breaking off.

Thread-Cutting Attachment
A key advantage of owning a lathe is the ability to machine threads. While taps and dies can cut many threads, acquiring a comprehensive tap and die set to cover all non-standard thread sizes can be costly. Sherline provides a unique and versatile thread-cutting attachment for its lathe. This affordable attachment enables you to machine thirty-six different unified thread pitches (ranging from 80 to 5 threads per inch) and twenty-eight different metric thread pitches (ranging from .25 to 2.0 mm). It also allows for both left-hand and right-hand threading. A 60° carbide cutting tool is included, but you can also grind a standard high-speed steel tool to cut various thread forms at any pitch diameter. This versatility allows you to machine both standard and non-standard inside or outside threads, as long as they fall within the lathe’s size limitations.
Note: Ensure you lubricate the gears with light oil before using the threading attachment.
The attachment includes:
- 15 aluminum gears
- Mounting brackets
- Engagement mechanism
- 4.00" (102 mm) handwheel
Thread cutting on the Sherline lathe is accomplished by gearing the spindle to the leadscrew. As the spindle is rotated using the handwheel mounted on the headstock spindle, the tool advances according to the gear ratio. Once the tool reaches the end of its movement, simply stop cranking, reverse the tool, and turn the spindle in the opposite direction until the tool passes its starting point. Reset the tool, and you’re ready for the next pass. It’s as straightforward as tapping! By using the supplied 127-tooth gear, you can cut true metric threads on an inch lathe or true inch threads on a metric lathe.
⚠️ Note: The thread-cutting attachment is not compatible with the 3C Headstock.
Adapting the Leadscrew Engagement Lever for Use with Digital Readout (DRO)
If you plan to use the leadscrew engagement lever with the Thread Cutting Attachment in conjunction with a Digital Readout (DRO), you will need to equip your lathe with the DRO sliding shaft (sold separately) for proper leadscrew engagement.Gear Selection Calculator
The Sherline Thread Attachment Calculator, created by Joo Beng Koh of Singapore, automates gear selection based on your desired thread count. Originally shared on the Sherline Lathe & Mill Facebook Group, Joo Beng graciously allowed us to feature this tool on our website. The calculator simplifies the setup process, particularly for users who frequently change their thread specifications.
For instructions, select the desired parameters in the light yellow fields, and the corresponding gear selections will appear in the green boxes. An accompanying image shows the correct gear placement along with step-by-step guidance for installation. This tool has greatly improved the process for Joo Beng and can help others as well.

Top Jaws for Extended Laser Pin Chuck Jaws
These extended pin jaws are specifically designed for laser marking operations that require holding parts with outer diameters up to 6" (153 mm) and inner diameters as small as 0.66" (16.7 mm), using Sherline 3-jaw chucks manufactured after 2014*. Each top jaw features four holes for 3/16" hard-steel dowel pins (not included) and mounts to the master jaws using a socket head cap screw (not included).
These jaws are intended for light-duty holding only and are not suitable for machining or any application requiring more than finger-tight clamping force. They are ideal for securely holding round parts—either internally or externally—during laser marking.
Compatible with all Sherline 3-jaw chucks.
*NOTE: Chucks manufactured before 2014 require custom fitting of each jaw. You may either send your chuck to Sherline for modification or measure the width of each jaw (A, B, and C) using micrometers and submit the measurements for proper fitting.

Ceramic Insert Tool Holder
Designed for cutting hard materials like tool steel, this ceramic insert tool holder features a triangular insert mounted at a negative rake angle. The downward tilt of the insert provides proper side clearance, allowing you to use all six cutting edges—three per side—before needing a replacement. The 3/8" shank fits Sherline’s P/N 7600 tool post (not included). A clamp, hold-down screw, and 3/32" hex key are included for secure installation. Replacement inserts are available as (P/N 22659).
Why Use Ceramic Inserts?
Ceramic cutting tools are a powerful addition to the modern machinist’s toolbox. Though more brittle than high-speed steel (HSS) or carbide, ceramic inserts excel at cutting hardened steels and other tough materials, especially at higher spindle speeds. This makes them ideal for jobs that would otherwise be extremely difficult or impossible—such as turning down the shank of an end mill.
This insert’s large nose radius helps achieve an excellent surface finish, particularly when profiling.
-
Each insert offers six usable cutting edges:
-
Rotate 120° to access a new edge (3 per side), then
-
Flip the insert for 3 more cutting points on the opposite face
-
-
In comparison, traditional carbide inserts offer only 2–4 cutting edges, making ceramic inserts cost-effective over time, despite the higher upfront cost.
Usage Notes & Safety Information
-
Ceramic inserts are brittle and should be used with proper technique to avoid chipping or breakage.
-
Caution: Chips produced during cutting can be extremely hot—even red-hot. Use protective eyewear, gloves, and fire-safe clothing when operating.
-
Some materials, such as tool steel, may form long, stringy chips that wrap around the part ("bird’s nest" effect).
Use a chip brush and stop the machine frequently to clear chips. These chip clusters can ignite if they come in contact with hot chips.

About the Carbide Inserts
While high-speed steel (HSS) tools remain the primary choice for miniature machine work due to their affordability and ease of resharpening, inserted-tip carbide tools offer significant advantages in specific applications. Carbide inserts excel in cutting harder materials, improving efficiency and tool life—making them invaluable in many professional machining environments.Safety Note
Carbide inserts can produce extremely hot chips and may shatter under stress. Always wear appropriate eye protection and safety gear when using these tools. Certain materials, such as tool steel, may form long, continuous chips that can wrap around the workpiece like steel wool. To minimize this, use a chip brush frequently or pause machining to remove chip buildup. These “bird’s nests” can ignite from hot chips, so maintain a clean workspace near the cutter.
Threading/Grooving Carbide Insert Tool Holder
Due to the variety of insert types and their cost, the holder is sold separately without inserts, allowing you to select only the specific inserts you need. The holder includes a clamp, 6-32 hold-down screw, and a 7/64" hex key for secure setup.
⚠️ CUSTOMER NOTICE — July 8, 2020
We’ve identified a potential issue affecting a small number of our Threading/Grooving Carbide Insert Tool Holders. Specifically, the cutting insert may not be securely clamped in place.
When tightening the clamp, the inside corner of the clamp may contact the step adjacent to the insert pocket, preventing full engagement with the clamping notch on the insert. This was caused by an early in-house clamp design that mistakenly used symmetrical angles on both sides of the clamp nose, rather than the intended asymmetrical design. This issue has since been corrected.
[caption id="attachment_33596" align="alignright" width="300"]
Click on the image for a larger view.[/caption]
To resolve the issue immediately:
-
Use a bench grinder or file to slightly grind down the back side of the clamp (see blue circle in the image).
-
This will allow the clamp tip to clear the step (indicated by the red arrow), ensuring full contact and proper clamping of the insert.
⚠️ CAUTION: Chips coming off the carbide inserts can be very HOT! Use extreme caution. Carbide inserts can also shatter. For these reasons, proper protective eyewear and clothing are especially important when using these tools. Materials like tool steel can form long, stringy chips that wrap around the part. Use a chip brush frequently, or pause machining to clear debris. Accumulated chips, especially when hot, can ignite. Keep the area around the cutter clean and free of chip buildup.

Linear Controller without Power Supply
The stand-alone controller is fully programmable via its built-in keypad and manages the operation of the connected stepper motor.
An 8-pin mini-DIN cable allows multiple controllers to be linked in a "daisy-chain" configuration. The controllers can signal each other to operate in sequence, enabling complex, multi-axis movements without the need for a computer or master CNC controller. They can also be used alongside existing CNC systems. Each controller can store two independent programs, with up to 40 steps per program. Each step can define distance, direction, speed, and whether the program pauses or proceeds automatically to the next step.
Sherline’s linear controller can also be daisy-chained with the rotary controller, allowing combined rotary and linear operations in sequence. This setup simplifies advanced tasks—such as gear cutting—without requiring CNC programming knowledge beyond what is entered via the keypad.
Items Included with the Linear Controller:
-
Linear controller with integrated keypad
Controller Power Supply Information:
The optional power supply is compatible with 110-240 VAC and automatically switches between voltages for use in regions with 220-240V mains power. (The original version of this power supply was 110 VAC only.)

Individual WW Collets
Collets offer a fast and accurate way to mount cylindrical parts or bar stock in a lathe. Each collet functions like a miniature precision 3-jaw chuck and fits into a tapered adapter mounted in the headstock. A drawbar passes through the headstock and threads into the rear of the collet, pulling it into the adapter. This action causes the collet jaws to close and securely grip the workpiece. Collets are known for their exceptional centering accuracy, but each collet size accommodates only a limited diameter range—typically ±.001" (0.02 mm).
WW Collets vs. Milling Collets
Unlike milling collets, WW collets feature a through-hole, allowing material to pass completely through both the collet and drawbar. The maximum diameter stock that can pass through is 3/16" (4.5 mm), although WW collets are available in sizes up to 5/16" (8.0 mm). Collets larger than the through-hole capacity are sometimes referred to as “pot chucks,” as they are only bored to a depth of approximately .260".
Collet Accuracy
Sherline WW collets are precision-made and have a maximum runout of .002" or less. When the WW collet adapter is properly trued as recommended in the instructions, runout is minimized, providing optimal accuracy. Pot chucks (collets larger than 3/16" or 4.5 mm) are not bored through and may exhibit increased runout if your part extends far beyond the front of the collet.
Logical Part Numbering
Sherline collets are organized by size for easy identification:
-
Inch Collets: Part numbers begin with 1160, followed by two digits representing the size in 64ths of an inch.
-
Example: P/N 116013 is 13/64"; P/N 116016 is 1/4" (16/64").
-
-
Metric Collets: Part numbers begin with 1178, followed by two digits representing the size in 0.1 mm increments.
-
Example: P/N 117813 is 1.3 mm.
-
Compatibility and Specifications
Sherline WW collets are manufactured in-house to standard WW specifications but are not hardened. The shank diameter is .312–.313", and the thread is .275-40. While some third-party WW collets may not fit properly, Sherline offers an optional .315" adapter and drawbar set (P/N 1163) to accommodate select 8 mm collets from other manufacturers.
Available Sizes
Sherline WW collets are offered in:
-
Inch sizes from 1/64" to 5/16", in 64th-inch increments.
-
Metric sizes from 0.3 mm to 8.0 mm, in 0.1 mm increments.
Special inch sizes up to .320" can be custom ordered with approximately a 3-week lead time. Please contact us for details.
Quck Order
If you are ordering a lot of different size collets please use the quick order table below to make it easier!
Headstock Riser Block Set
The standard Sherline lathe can accommodate parts up to 3.5" (90 mm) in diameter. However, there are times when you may need to work on larger pieces. The Sherline headstock spacer block increases the lathe’s maximum working diameter to 6" (152 mm), significantly expanding its capabilities.
This set includes a 1.235" (31.37 mm) spacer block that fits beneath the headstock, along with a riser-rocker tool post to elevate the cutting tool accordingly. If you plan to turn parts between centers while using the headstock riser, you’ll also need a tailstock riser block to maintain proper alignment.
Note: Although the spacer block allows turning parts up to 6" in diameter, the lathe’s motor power remains unchanged. This accessory is best suited for machining easy-to-cut materials or for occasional use when extra clearance is needed. If your work frequently requires this added capacity, upgrading to a larger lathe may be advisable.
Steady Rest
All materials tend to deflect away from the cutting tool when you are turning them on a lathe. This tendency is especially noticeable on long, slender parts and long pieces of bar stock, which makes it quite difficult to hold close tolerances. The best way to support a long section is with a center mounted in the tailstock. However, for one reason or another, this is not always possible. As an example, it may be a piece of stock that you want to center drill so that you can mount it between centers, or it may be a part where a center drill hole would ruin the looks of the piece. Whatever the reason, a steady rest provides a means of supporting the piece while it turns.
The Sherline steady rest has three adjustable brass blades mounted in a holder that mounts on the bed of the lathe. These blades can be adjusted to the diameter of the part to provide the necessary support. Another advantage of the steady rest that is often overlooked is the fact that work held in position by the rest turns concentrically with its outside diameter. This means that concentricity is assured when working near the steady rest, because, at that point, it must be running perfectly true despite imperfections in how it is chucked or centered at either end. The Sherline steady rest will accommodate any size part, up to 1.75" (44mm) in diameter.
A steady rest riser block is available, which makes it possible to use the steady rest on the lathe with the headstock and tailstock riser blocks in place.

Horological Milling Machine Bushing and Depthing Accessory
This accessory was developed based on a concept shared by longtime Sherline user and Craftsman of the Year, Jerry Kieffer. The idea is to adapt a small milling machine for multiple clock and watch repair tasks - replacing the need for several specialized tools. It simplifies and enhances depthing by letting you position a gear exactly where it needs to be, check its mesh with a mating gear, and then precisely machine the bushing hole in the correct location.
With the Sherline mill, you can precisely position and align clock and watch components, allowing for highly accurate machining of bushing holes in both size and location. Once the machining is complete, the mill can also serve as a manual press for bushing insertion.
Used in combination with your Sherline mill, this accessory transforms your setup into a versatile three-in-one clock and watch repair machine - while retaining the full functionality of a precision milling machine.
The photos show the depthing attachment on a 5400 mill. If you want to use it on a 5000-series mill you will need to add the headstock spacer block.
High Speed Steel Boring Tool
Lathe tools, or tool bits as they are sometimes called, are the cutting tools that are used for turning and facing work on the lathe. The most popular lathe tools are those made of high-speed tool steel (HSS). They can … Continued
Left Hand HSS Tool
Lathe tools—often referred to as tool bits—are the primary cutting tools used for turning and facing operations on a lathe. The most common type is made from high-speed steel (HSS), which is suitable for machining a wide range of materials, including wood, plastic, aluminum, brass, and steel. HSS tool blanks are relatively inexpensive and can maintain their hardness at temperatures up to 1000°F (588°C), making proper control of depth of cut, cutting speed, and feed rate essential.
A major advantage of HSS tools is how easily they can be sharpened. They can be shaped and resharpened using a standard aluminum oxide grinding wheel and, once sharpened, will hold their edge for a long time.
NOTE: A lathe tool is named for the direction the chip exits the tool. A right-hand tool has its cutting edge on the left, causing the chip to peel off to the right.

CNC Linear Controller with Power Supply
This stand-alone controller features an integrated keypad for easy programming and controls the operation of the connected stepper motor—no external computer or CNC system is required.
An 8-pin mini-DIN cable allows multiple controllers to be connected in a daisy-chain configuration. Each unit can send and receive signals to operate in sequence, enabling multi-axis motion without a master CNC controller. The controllers can also interface with existing CNC systems for more complex setups.
Each controller supports two independent programs, with up to 40 steps per program. Each step can define travel distance, direction, speed, and whether to pause or automatically continue to the next command.
The linear controller can also be daisy-chained with Sherline’s rotary controller, enabling combined linear and rotary motion. This simplifies more advanced tasks—such as gear cutting—without requiring any G-code knowledge beyond the simple keypad inputs.
Included with the Linear Controller:
-
Linear Controller with Keypad

Mill Collet Set
Sherline milling collets are specifically designed for use with the Morse #1 internal taper, which is standard on both the Sherline lathe and vertical mill. Due to the shallow angle of the Morse #1 taper, tightening the drawbolt results in significantly greater clamping force compared to WW collets. For this reason, we recommend using these milling collets to securely hold miniature end mills (with 3/16" or 1/4" shanks), #1 and smaller center drills, Dremel® bits (1/8" shank), and a variety of other small cutters.
Inch Mill Collet Set: 1/8", 3/16", 1/4"
Metric Mill Collet Set: 3 mm, 4 mm, 6 mm
Note: Tools held in these collets must have a shank diameter within .001" of the stated size. Because of the shallow taper, the collet will remain tight in the spindle even after loosening the drawbolt. To release it, back the drawbolt out a few turns and tap it lightly to free the collet.
⚠️ CAUTION: When tightening the collet drawbolt with a Tommy bar, be careful not to insert the bar too far into the spindle. Doing so can damage the collet’s taper area. The red arrow in the image below shows an example of this type of damage.

Single-Axis Slide with Programmable CNC Contoller
Sherline’s single-axis controllers are designed to drive the stepper motor on any individual axis of a lathe or mill—no separate computer or driver is required. Each controller features an integrated computer chip within the keypad/control unit, allowing you to operate the motor directly from the keypad or enter simple programmed sequences—no G-code knowledge needed.
You can program parameters such as direction, travel distance, feed rate, and whether to pause between operations or proceed automatically to the next step. The controller can store up to 40 steps (each with four parameters) in either of two user-defined programs. Multiple controllers can be linked via cable to synchronize movements or can be connected to a larger CNC system using “sense” and “acknowledge” signals to coordinate actions within a CNC sequence.
Stepper Motor Mounting & Drive System
Each stepper motor mount includes dual ball bearings with a preload nut to eliminate endplay. A dampened coupling connects the motor’s 1/4" diameter shaft to the leadscrew. The dual-shaft stepper motor also allows for manual operation using the provided handwheel. The controller employs micro-stepping for precise, smooth movement.
Mounting Options
-
From the Bottom: Four 1/4-20 holes on 2" centers in the base for mounting from below.
-
From the Top: If bottom access is unavailable, use the included four angle clamps that fit into the perimeter groove of the base. Drill and tap the mounting surface for the included 10-32 socket head cap screws. Use all four clamps for maximum stability.

Power Supply
The included power supply operates on 115/120 VAC, 60 Hz (38 W). For regions with 100, 220, or 240 VAC and/or 50 Hz power, a step-down transformer is required. Alternatively, you may supply 24VDC, 1A (1000 mA) from a compatible local power source. Sherline does not offer a 220V power supply or transformer.
Weight Capacity
The slide has a weight capacity of approximately 10 lbs, depending on table length and load placement. For an 18" table, limit off-center loads (at the table end) to no more than 10 lbs. Heavier loads may be supported if centered near the base.
Duty Cycle & Maintenance
Under heavy, continuous use, you may observe wear on the anodized dovetail surfaces after one year (approx. 2080 hours). The slide remains fully functional, but regular lubrication with light oil is recommended to maximize lifespan.
IMPORTANT: Do not use WD-40 for lubrication. It will strip the anodized coating.

CNC Linear Controller with 15″ Leadscrew
This linear controller package includes a stepper motor mount and a 15" leadscrew for use on Sherline lathes that are not CNC-Ready. The stand-alone controller is programmable through its integrated keypad and directly controls the attached stepper motor, which is mounted to drive the lathe’s leadscrew. (A separate kit with a 24" leadscrew is available for 4400-series lathes—P/N 8880.)
An 8-pin mini-DIN cable allows multiple controllers to be connected in a “daisy-chain” configuration. The controllers can signal each other to operate in sequence, enabling complex multi-axis operations without the need for a computer or master CNC controller. The system can also be used in conjunction with existing CNC controllers. Each unit can store two separate programs, with up to 40 steps per program. For each step, you can define travel distance, direction, feed rate, and whether the sequence pauses or advances automatically.
The linear controller can also be daisy-chained with Sherline’s rotary controller (P/N 8700), allowing coordinated rotary and linear motion. This makes it easy to perform sophisticated operations—such as gear cutting—without any CNC programming knowledge beyond the keypad interface.

CNC Linear Controller – Z-Axis
This stand-alone controller is programmable from its keypad and controls the stepper motor's function to which it is attached.
An 8-pin mini-DIN cable can be used to connect multiple units in a "daisy chain." The units can signal each other to work in sequence, allowing multiple movements to be accomplished without using a computer or master CNC controller. They can also be used in conjunction with existing CNC controllers. The controller is user-programmable with two separate programs of up to 40 operations each. In each block, you can control distance, direction, speed, and whether the program pauses or proceeds to the next block.
The linear controller can also be "daisy-chained" with Sherline's rotary controller to achieve rotary and linear movement combinations. This makes it easy to set up for relatively sophisticated operations like cutting gears without having to know anything about CNC programming beyond what is entered from these simple keypads.
Using a power feed offers several advantages:- A constant feed rate gives a smoother, more consistent final finish
- The chance of errors due to miscounting handwheel revolutions is reduced

36V Closed-Loop Stepper Motor
The 36V stepper motor is a closed-loop motor with an integrated driver, housed in the same NEMA 23 frame as our standard stepper motor. It features built-in LED indicators that display both power and alarm status for easy monitoring.
⚠️ NOTE: The 36V closed-loop stepper motors are sold only as replacement parts for Sherline Accu-Pro machines. They are not available as upgrade components for pre-existing systems.
High-Torque Stepper Motor
Sherline’s high-torque stepper motor features the same NEMA 23 frame size as our standard stepper motor but delivers over 75% more torque - ideal for increased cutting feed rates and better performance on the Z-axis, where it can handle the added weight of the motor and headstock. Note that maximum rapid feed rate remains unchanged.
Important Compatibility Note: Due to the increased torque, these motors require an updated CNC coupler (P/N 671052, sold separately). If upgrading from systems using the discontinued coupler (P/N 67105), ensure you purchase the correct replacement.
Rated at 2 amps, these motors are fully compatible with all Sherline CNC machines, including complete CNC systems, our 4-axis driver box, CNC rotary tables and our linear and rotary motion controllers. No additional power supply upgrades are needed.
Dual-shaft design allows handwheel operation for manual control. Flats are precision-ground on both ends to secure handwheels and couplers via set screws. When used with Sherline motor mounts, the shaft end engaging the coupler must have a flat to prevent damage from the set screw. This may not be necessary in non-Sherline applications.
Each motor includes a six-lead cable with a 5-pin connector, pre-wired to interface seamlessly with Sherline's CNC equipment, making setup fast and easy - just plug in and go.
Stepper Motor
Sherline stepper motors feature shafts at both ends, allowing for manual control via a handwheel, if desired. Flats are ground onto each shaft to accommodate set screws for the handwheel and coupling. For use with a Sherline motor mount, ensure that the shaft entering the coupling has a flat machined or ground onto it where the set screw secures it. Failure to do so may damage the shaft, making the coupling difficult to remove. For non-Sherline applications, the flat may not be necessary.
Powerful Dual-Shaft Motors
-
P/N 67127: This motor comes pre-wired with six leads in a connector that plugs directly into Sherline's linear or rotary controllers. Both our CNC system and driver box include four pre-wired cables with 5-pin plugs that match the P/N 67127 stepper motor. Simply plug each stepper motor into the corresponding axis cable for an easy setup.
-
P/N 67130: This motor features six raw wire leads, and does not include a connector, so that it can be used with non-Sherline controllers that have a different pin configuration.
Note: Due to the lack of standardization in the industry, wire colors can vary between suppliers. If using a connector not supplied by Sherline we recommend using a continuity checker to identify which wire connects to each pin on the DIN plug. Typically, the black and white (or tan) wires are connected to the center pins, but other colors may vary. See our specifications sheet for wiring diagram.

- Metric models show position to 0.01 mm
The system supports both ball screw and leadscrew machines. As well as the ability to use Metric DROs on inch machines or inch DROs on metric machines. It features six selectable modes based on machine type (mill or lathe), screw type (leadscrew or ball screw), and preferred display units (inch or metric). For setup instructions, refer to the official DRO Mode Instructions.
You can electronically compensate for backlash by inputting the measured backlash value for each axis. When the direction of handwheel rotation reverses, the DRO subtracts the backlash before updating the position—eliminating common errors and making it easier to track travel distance and direction. The power supply automatically switches between 120V and 240V, making it suitable for use in countries with 220–240V electrical current. A socket adapter may be required outside North America.

Sherline recommends dual-shaft stepper motors so manual control is still possible using the included handwheels, which mount to the rear shaft once the motors are installed. Sherline also offers high-quality stepper motors and CNC components to complete your system.
Additionally, you can explore various aftermarket suppliers for compatible motors, drivers, and software. Visit our CNC Dealers page for a list of suppliers and links to their websites.
Note on Ordering a Metric Mill – Most Sherline cutting tool, such as center drills, are offered in fractional sizes. If you opt for a metric machine with metric collets or holders, you’ll need to order compatible fractional-size holders to use these tools effectively.
