Left hand - This insert cutter is designed with the screw-on feature and a reverse helix (downward shear) making it efficient as well as effective.

The insert cutter exposes two edges of the insert, thus allowing for plunge cutting. The open throat style makes for cooler running. This insert cutter is available in right and left hand thread. The #INSERT-12 carbide insert has had all four corners custom ground to an 1/8" radius. This cutter will work with any ¼"-28 thread arbor.
