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.
The advantages:
1, Hard formation application
Medium parabolic crown profile and heavy desity cutter layout provide the high ROP in high compressive strength and high abrasive formations.
2, High ROP
Unique cutter arrangement and location can keep cutting dege sharp in the drilling to obtain the maximum ROP.
3, Multi-function hydraulics
Deep slot and straight blade design can get high ROP in medium hard formations and can effectively cool the bit in hard and abrasive formations.
