Guilin Star Diamond PCD inserts

Introduction of PDC 

PDC is made of diamond micro-powder and hard tungsten carbide under high temperature and high pressure. It 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.

Apllications

This kind of PDC is sintered at high pressure and temperature, which is composed of diamond and kentanium. It can be embedded into mine drill that used in shallow stratum drilling, which is economic and durable.  

Advantages

1. high hardness, abrasion resistance and impact resistance

2. high speed

3. Cutter layout is force balanced to drill a precise round hole and reduce bit whirl

4. Gauge pads have tungsten carbide inserts for maximum wear resistance

5. The diamond layer with thickness over 1 mm increases abrsion resistence of PDC cutter.
