Introductionof PDC (Polycrystalline Diamond Compact)
PDC is made of diamond micro-powder and hard tungsten carbide under high temperature and high pressure
Possess of high wear resistance like diamond, at the same time the impact resistance like tungsten carbide and that's made it the best material as a drill bit cutter
Reinforced PDC has higher dense diamond powder, claw tungsten carbide substrate made the two layers solid as whole one
So, the reinforced PDC of supper wear resistance, longer service life and high efficiency

Characteristics:
(1) All products are under ISO certificate and quality control
(2) They have high efficiency and strong wear resistance for drilling
(3) Applicable rock formation: f≤8
