Indexable Turning Tools

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.

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 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.

Turning Carbide Insert Holders

Secure carbide inserts inside these holders for stable turning.

Parts for Carbide Insert Holders

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

Economy Indexable Turning Tools

These tools come with carbide inserts installed. When one edge of the insert dulls, rotate it to use a sharp edge.

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.

Indexable Boring Tools

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.

Boring Carbide Insert Holders

These holders conform to ANSI standards.

Boring Carbide Insert Holders with Coolant Hole

Deliver coolant through the holder to keep workpieces cool while boring tough materials, such as steel, stainless steel, and nickel-based alloys.

Economy Indexable Boring Carbide Insert Holders

Use these tools to enlarge existing holes to precise diameters. They come with an insert installed. When one edge of the insert dulls, rotate it to use a sharp edge.

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.

Indexable Threading Tools

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-Performance Carbide Insert Holders
for External Threading and Grooving

Pair these holders with a threading insert or a grooving insert to make cuts on the outside of a workpiece.

High-Performance Carbide Insert Holders
for Internal Threading and Grooving

Pair these holders with a threading insert or a grooving insert to make cuts on the inside of a hollow workpiece.

Economy Indexable Threading Tools

A carbide insert comes installed on these tools.

Indexable Cutoff and Grooving Tools

Indexable Cutoff and Grooving Carbide Inserts

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

Cutoff and Grooving Carbide Inserts

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

Blade-Style Cutoff and Grooving Carbide Insert Holders

Pair these holders with a tool block for right- and left-hand mounting in a lathe.

Indexable Grooving and Profiling Carbide Inserts

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

Blade-Style Holders for Indexable
Cutoff and Grooving Carbide Inserts

Pair these holders with a tool block for right- and left-hand mounting in a lathe.

Shank-Style Cutoff and Grooving Carbide Insert Holders

Fit these holders directly into a lathe tool post or appropriately sized holder without the need for a tool block.
