PCD is polycrystalline diamond, manufactured by sintering together carefully selected diamond particles at very high temperature and pressure in the presence of a solvent/catalyst metal.

The result is an extremely tough intergrown mass of randomly orientated diamond crystals bonded to a tungsten carbide substrate. PCD, therefore, can be regarded as a composite material which combines the hardness, abrasion resistance and high thermal conductivity of diamond with the toughness of tungsten carbide.

Correctly applied, PCD tooling replaces existing cutting tool materials such as HSS or tungsten carbide. Tool costs per component are reduced through extended tool life and minimal downtime.

COURMATT uses only PCD. After leaving the sintering press the round blanks (or discs) are diamond ground to the required finishes and these discs can be further cut into a variety of shapes and sizes, for use on multi-tipped rotary tools, such as routers and circular saws.

PCD is available in 3 standard grades--002, 010 and 025 (equivalent to 2, 10 and 25 microns average diamond grain size). a new grade of PCD. Which was developed with the requirements of the woodworking industry very much in mind.
