Indexable Turning Tools

Economy Carbide Inserts

Use these carbide inserts for general purpose turning.

Carbide Inserts for Multiple Materials

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

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.

Carbide Inserts for Heat-Resistant Super Alloys

Heat resistant and wear resistant, these inserts cut super alloys—such as Inconel and Waspaloy—and titanium better than general use inserts.

Carbide Inserts for Non-Ferrous Materials

Cut aluminum, copper, brass, and other non-ferrous materials with these premium inserts.

Carbide Inserts for Stainless Steel

Heat resistant and shaped for turning stainless steel specifically, these inserts will last longer than inserts for multiple materials.

Carbide Inserts for Cast Iron

Made of an abrasion-resistant carbide designed for turning cast iron, these inserts will last longer than inserts for multiple materials.

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.

Cubic Boron Nitride Inserts

Resisting wear and fractures when cutting hardened steel, these cubic boron nitride inserts last longer than carbide inserts.
