Carbide Inserts (thread, groove)
These Carbide inserts are used in the Insert Tool Holder and are used for either threading or grooving.
Thread Cutting
1/4″ 3-Flute End Mill Set
3/8″ Double-Ended End Mill Sets
These precision 3/8″ shank double-ended end mill sets are a versatile and budget-friendly choice for general milling work. Double-ended cutters give you two cutting ends in one tool, doubling your productivity and value. Each cutter features a flat section on the shank for secure clamping in a 3/8″ end mill holder.
Both sets include six popular diameters: 1/8″, 5/32″, 3/16″, 1/4″, 5/16″ and 3/8″.
7400 – 2-Flute Set
Ideal for softer materials such as aluminum, these 2-flute cutters resist clogging and provide smooth chip evacuation.
7401 – 4-Flute Set
With four cutting edges, this set offers increased cutting contact and is better suited for harder materials like steel.
Each set includes a wooden storage block to protect your cutters when not in use
CAUTION: Unlike a drill bit that looks similar, end mills are sharpened on the edges as well as the tip. These sharp edges demand a lot of respect when being handled and used! Also, to keep them sharp, store them in the block provided or individually protected in your toolbox.
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:
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.
Boring Tools
These high-speed steel cutting tools are designed specifically for use with the Sherline boring head and feature a 3/8" (9.5 mm) diameter shank.
If needed, the tools can be ground to fit smaller hole diameters. They may also be used in the 3/8" round-hole tool post on a lathe for boring operations. Each tool includes a ground flat on the shank to provide a secure surface for the boring head setscrew.
