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 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.

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.

Cubic Boron Nitride Inserts

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

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.

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.

Lathe Tools

Diamond-Tipped External Threading Lathe Tools

When cutting threads in nonferrous and nonmetallic materials, such as aluminum, copper, fiberglass, and plastic, diamond tips provide superior cutting performance.

Diamond-Tipped Turning Lathe Tools

The diamond tip on these tools offers superior cutting performance on nonferrous and nonmetallic materials, such as aluminum, copper, fiberglass, and plastic.

Screwdriver Bits and Adapters

Hex Bits for Impact Drivers

The toughest bits available, these withstand the shock and twisting force of impact drivers.

Torx Bits for Impact Drivers

The toughest bits available, these withstand the shock and twisting force of impact drivers.

High-Torque Torx Bits

Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine screws.

Phillips Bits for Impact Drivers

The toughest bits available, these withstand the shock and twisting force of impact drivers.

High-Torque Phillips Bits

Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine screws.

Square Bits for Impact Drivers

The toughest bits available, these withstand the shock and twisting force of impact drivers. Designed for screws with a square recess in the head, they are also known as Robertson bits.

High-Torque Slotted Bits

Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine screws.

Pozidriv® Bits for Impact Drivers

The toughest bits available, these withstand the shock and twisting force of impact drivers.

Bit Assortments for Impact Drivers

The toughest bits available, these withstand the shock and twisting force of impact drivers.

High-Torque Bit Assortments

Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine screws.
