Indexable Lathe Tools

High-Speed Steel Inserts for
Indexable Threading Tools

Indexable Threading Tools

These tools come with one high-speed steel insert for use on steel and stainless steel and one high-speed steel insert for use on softer materials, such as aluminum and brass. When one point of an insert dulls, rotate it to use a sharp point.

High-Performance Threading Carbide Inserts

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

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.

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 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.

Internal Profiling Carbide Insert Holders

Contour the interior wall of a hollow workpiece when you pair a holder with a compatible insert.

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.

Lathe Tools

Solid Carbide Internal Threading Lathe Tools

Solid carbide provides more rigidity than carbide-tipped tools.

Carbide-Tipped Internal Threading Lathe Tools

A carbide tip brazed onto a ground steel shank makes these tools less brittle than solid carbide tools.

Carbide-Tipped External Threading Lathe Tools

The carbide tip brazed onto the ground steel shanks of these tools is more wear resistant than high-speed steel.

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.

Quick-Change Lathe Tools and Holders

Reduce tooling setup time—install the holder once and alternate between applications by switching out the bit.

Carbide-Tipped Turning Lathe Tool Sets

Constructed of a carbide tip brazed onto a ground steel shank, these tools are more wear resistant than high-speed steel tools.
