Compax* Diamond Tool Blanks
for Machining Nonferrous and Nonmetallic Materials

Diamond Innovations, a leader in superhard cutting materials, manufactures a complete line of high quality sintered diamond Compax tool blanks. Polycrystalline diamond (PCD) is used for machining a wide variety of nonferrous and nonmetallic materials. Different blank shapes, sizes and grades, tailor-made to achieve maximum productivity in their respective application fields, are provided to toolmakers for fabrication into finished cutting tools.

Compax polycrystalline tool blanks consist of the highest quality micron sized particles of Man-Made* industrial diamond, sintered and integrally bonded to a cemented tungsten carbide substrate using a high temperature high pressure process.
