Sherline offers a 4″ rotary table and industrial slides that are popular in the laser marking and scanning industries. Also offered are round and rectangular tooling plates that are specifically designed to mount parts on top of the tables for scanning or marking.

If you prefer jaws with a looser fit for faster operation (where maximum accuracy isn’t critical), add a note requesting “loose jaws” below.
-
Soft steel jaws (unhardened and unmachined) are also available when building your own chuck.
- Ductile plating with columnar structure
- Harder than any other nickel-based coating
- Coating uniformity that eliminates post-plate grinding (or burnishing)
- Wear properties overall superior to hard chromium
- Hardness (68-72 Rc)
- Low coefficient of friction (.044) Teflon™ is .04
- Uniform coating thickness up to .004”
- Accepts dry film lubricants
- For those who have jobs where speed and ease of use are more important than maximum accuracy and want a chuck that is loose right from the start (No extra charge). Add the note “loose jaws” to the comments box below
- Soft (not hardened or machined) steel jaws are also available when you build your own chuck.

2.5″ 3-Jaw Chucks – Various Thread
Sherline 3-jaw chucks are designed with synchronized jaws that move together to automatically center round or hex stock to within a few thousandths of an inch. They offer the fastest and most convenient way to hold work in a lathe, making them one of Sherline’s most popular accessories.
These chucks can grip externally on bar stock or internally on tubing. The jaws are reversible to handle a wider range of part sizes.
Compatibility with Sherline and Other Lathes
Chucks are available with different spindle threads for use on Sherline lathes (3/4-16) and other machines such as older Unimat models (12mm x 1mm or 14mm x 1mm) or Sears 6" lathes (1/2-20).
Note: Thread sizes other than 3/4″ x 16 are custom made and require 5–7 business days.

2.5″ 3-Jaw Chuck – Electroless Nickel Coated
This chuck is identical to P/N 1041 except for an electroless Nickel coating that has been applied to help prevent wear and corrosion. This special coating has been applied to all external and internal surfaces of the chuck (except for chuck jaws), significantly improving the life of the chuck. This chuck also opens and closes more smoothly due to the lubrication properties of Nickel-Teflon.
Some of our customers have been wondering how to tell the difference between our standard chucks and those that have the electroless Nickel coating. Standard chucks have darker markings than the coated chucks (See Figure 1. Click on photo to view a larger image).

Figure 1—Examples: (Left) 1040 3-Jaw Chuck (3.1″), (Right) 1040C Electroless Nickel Coated 3-Jaw Chuck (3.1″).[/caption]
Here, at Sherline Products, each of our chucks is laser engraved with a company mark, chuck size, and jaw location. During the laser marking process the laser removes a bit of the surface and darkens the material below (Figure 1, left). When chucks are sent out to receive the Nickel finish the coating process changes the dark engraved markings to a noticeably lighter finish (Figure 1, right).
There is also a subtle change in the color of the chuck, but in the absence of being able to compare them side by side, the most evident way to tell whether you have a coated chuck, or not, is to check the color of the laser markings.
3.1″ 3-Jaw Chuck
This larger chuck takes up no more center-to-center space than the 2.5" chuck, but it will hold larger work. It has a clamping range of 3/32" (2 mm) up to 1-1/2" (38 mm) diameter with the jaws in the normal position. With the jaws in the reversed position, work up to 3-1/4" (82.5mm) can be gripped. The hole through the chuck is .687" (17 mm). Rotating the knurled ring closes all three jaws simultaneously to grip round or hexagonal stock quickly. Tommy bars (provided) are used in the side holes to tighten and loosen the chuck for more leverage. The chuck has a 3/4-16 thread to fit Sherline's spindle.

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.
