Milling, Routing, and Turning

Carbide Inserts for Multiple Materials

Choose these premium turning carbide inserts to cut a variety of materials without changing out your tool.

Economy Carbide Inserts

Use these carbide inserts for general purpose turning.

Carbide Inserts for Steel

Optimized for use on steel, these inserts can run at higher cutting speeds and will last longer than inserts for multiple materials.

Turning Carbide Insert Holders

Secure carbide inserts inside these holders for stable turning.

Alumina Ceramic Inserts

These inserts are made with a black alumina ceramic on the cutting edges. Compared to carbide inserts, ceramic lasts longer in hardened-steel tooling applications because it is chemically inert and has better heat resistance.

Form concave or convex edges on a workpiece.

Replaceable Carbide-Insert Face Milling Cutters

Combine a cutter with carbide inserts to create a face milling cutter, also known as indexable face milling cutters.
