Contour Fine Tooling is pleased to announce the availability of a new type of diamond making it possible to cut Tungsten Carbide.

The CVD-Diamond is a polycrystalline diamond grown by plasma-assisted Chemical Vapor Deposition (CVD) technology. It is one of the most versatile engineering materials available. Features are:

The properties of CVD diamond have a very positive effect on wear resistance when used as a cutting tool on hard non-ferrous materials. Test results have shown that tungsten carbide with a Cobalt percentage of 6% and more is machinable with good results.

Results which are achieved with a CVD-Diamond tool with radius of 0,8mm on Tungsten Carbide with 10% Cobalt and Hardness 1680HV:
