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.
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″ 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
