Indexable Lathe Tools

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.

Tool Blocks for Blade-Style Cutoff
and Grooving Carbide Insert Holders

Mount blade-style holders to a lathe tool post or turret.

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.

Indexable Cutoff and Grooving Carbide Inserts

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

Shank-Style Holders for Indexable
Cutoff and Grooving Carbide Inserts

Turning Carbide Insert Holders

Secure carbide inserts inside these holders for stable turning.

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.

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.

Internal Profiling Carbide Insert Holders

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

Lathe Tools

Chip-Breaking High-Speed Steel Cutoff Blades

A thinner cutting edge and thicker top edge give these blades a T‐shape profile that moves chips away from the cut and reduces friction for fast cutting.

High-Speed Steel Cutoff Blades

Also known as parting blades, use these to separate a finished part from the workpiece.

Carbide-Tipped Cutoff Blades

The carbide tip brazed onto these blades is more wear resistant than high-speed steel.

Carbide-Tipped External
Grooving and Cutoff Lathe Tools

A carbide tip brazed onto a ground steel shank makes these tools more wear resistant than high-speed steel tools.

Cutoff Blade Holders

Place a cutoff blade into one of these holders to keep it in place in the lathe.

Cutoff Blade Holders for Quick-Change Lathe Tool Posts

Cutoff Blade Holders for
Quick-Change Lathe Tool Posts
