The production of polycrystalline diamond, or PCD, occurs synthetically by sintering together many particles of diamond, usually 2 to 30 microns in size, with a metal binder (usually cobalt) under high pressure and temperature. There may be 90-95% diamond particles in PCD, and the rest is the binder. PCD is commonly used in cutting tools […]

For composites, diamond cutting tools can be divided into two types: PCD tools, which are built from PCD segments of a specific size and shape, and CVD diamond coated tools, which are built entirely in a grinding operation and then coated with CVD diamond.
