Lathe Tools

High-Speed Steel Cutoff Blades

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

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.

Carbide-Tipped Cutoff Blades

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