Description

Product Overview

BM Italy rotary broaches are precision-engineered tools that produce hexagonal, square, Torx, and other polygonal socket forms in a single rotary cutting pass on CNC lathes and machining centers. The tool’s self-rotating insert engages the workpiece at a 1° offset angle, creating the form while rotating at the workpiece spindle speed. Italian engineering delivers superior tool life and dimensional accuracy.
