Indexable Lathe 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 Stainless Steel

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

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 Non-Ferrous Materials

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

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 Cast Iron

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

Cubic Boron Nitride Inserts

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

Economy Indexable Turning Tool Sets

These sets have five indexable turning tools with carbide inserts and a wood storage stand. When one edge of a tool's insert dulls, rotate it to use a sharp edge.

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.

Parts for Carbide Insert Holders

Replace clamps, screws, seats, and slotted pins in carbide insert holders.

Cutoff and Grooving Carbide Inserts

Combine a holder and carbide insert to perform cutoff and grooving tasks on a lathe.

Indexable Cutoff and Grooving Carbide Inserts

Cut square corner grooves in a workpiece or cut completely through a part.

Indexable Grooving and Profiling Carbide Inserts

The rounded nose on these inserts contours the outside of the workpiece and cuts grooves with rounded edges.

Carbide Inserts for Boring Carbide
Insert Holders with Coolant Hole

Pair one of these inserts with a compatible boring carbide insert holder with coolant hole.

Economy Indexable Boring
Carbide Insert Holder Sets

These sets have a variety of indexable boring insert holders with carbide inserts and a wood storage stand. When one edge of a tool's insert dulls, rotate it to use a sharp edge to enlarge existing holes to precise diameters.

High-Performance Threading Carbide Inserts

Install these inserts into a compatible holder to cut external or internal threads on a workpiece.

High-Performance Grooving Carbide Inserts

These inserts can cut grooves on both the outside and inside of a workpiece depending on the holder used.

High-Speed Steel Inserts for
Indexable Threading Tools

Carbide Inserts for Internal
Profiling Carbide Insert Holders

Combine a carbide insert with a compatible internal profiling holder to create a tool that can contour the interior wall of a hollow workpiece.
