Introduction of PDC (Polycrystalline Diamond Compact):

PDC is made of diamond micro-powder and hard alloy substrate under high

temperature and high pressure. It possess of high wear resistance like

diamond, at the same time the impact resistance like hard alloy and that’s

made it the best material as a drill bit cutter. Reinforced PDC has higher

dense diamond powder, claw hard alloy substrate made the two layers solid

as whole one. So, the reinforced PDC of supper wear resistance, longer

service life and high efficiency.
