Abstract:
A broach which has several cutting elements and a support unit to which the cutting elements are attached is made by cutting the cutting elements through electric-discharge machining, in particular wire-EDM so that the production thereof is less time consuming and less expensive. Moreover, the cutting elements can already be made to final size and final hardness.
