As the backbone of stamping and metal forming, tungsten carbide EDM blocks resist the corrosion, pitting, and cracking commonly experienced during electrical discharge machining, especially in thick punches and large die segments.

We offer a wide variety of carbide grades for EDM blocks, including fine, medium, and course-grained tungsten carbides with a mixture of binders and additives to create the right balance of toughness, hardness, abrasion and corrosion resistance of the application.

A comprehensive standard selection of tungsten carbide EDM blocks in various dimensions for each grade is available in the below tables, but other sizes, tolerances & configurations also available on request.
