Specifications
Tungsten Carbide PDC Substrate
RECOMMEND GRADES and SPECIFICATIONS:
Polycrystalline diamond (PCD) is very hard, even harder than tungsten carbide. so there're polycrystalline diamond cutter (PDC), which use a tungsten carbide substrate and layer of PCD coated. this structure can adapt the strength of carbide and hardness of diamond both, so the working life is much longer than others.
