Abstract
A broaching tool is manufactured directly from a heat hardened blank of preformed metal by having a grinding wheel of CBN (cubic boron nitride) material cut a broach tooth from the hardened blank by cutting gullets in the blank. The blank is made movable and rotatable relative to the CBN grinding wheel to allow the manufacture of a series of broach teeth forming a broaching tool with various tooth spacings, depths, and angles with respect to the face of the broaching tool.
