Create your own versatile milling cutters. These kits include a cutter body, inserts, wrenches, and screws. Also known as indexable end mills, replaceable insert milling cutters remove metal at least two times faster than comparable high-speed steel milling cutters. When the cutting edges dull, replace the carbide inserts instead of the entire tool. The inserts come factory sealed from the manufacturer for maximum traceability.

Use with an R8 shank arbor (sold separately).

Titanium-diboride (TiB2) coated inserts reduce friction in nonferrous metals and composites, so you can use them without lubrication in material like aluminum, fiberglass, and plastic. Titanium-aluminum-nitride (TiAlN) coated inserts dissipate heat better than other inserts, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the inserts cool, even when used without lubrication.

Kits come with either octagon or square inserts. Use octagon inserts for general face milling. With eight cutting edges, they generate smooth cuts. Use square inserts to create a 90° corner when shoulder milling.

Use these tools with low-horsepower, manual milling machines. They have clamps for holding inserts that do not have a mounting hole. Replaceable carbide-insert end mills reduce waste and cost in high-volume jobs—when the cutting edges dull, replace the carbide inserts instead of the entire tool. End mills have a square cut style for milling square slots, pockets, and edges. All are noncenter-cutting for operations where the sides of the teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts.

R8-shank end mills have internal threads on the tapered end for connecting to a drawbar.

Carbide inserts have a wear-resistant titanium-nitride (TiN) coating.
