PDC coring drill bits(for coal mine use and geological exploration)

ISO9001:9002 certificated 10years manufacturing experience Super antiwear characteristic Super long lifetime Solid quality

Product Advantages:

1. PDC cutters for high speed drilling;

2. All cutters are premium grade for extended bit life and durability;

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

4. More total footage, faster ROP, reduced cost-per-foot;

5. Advanced geometric design for faster penetration;

6. Gauge pads have tungsten carbide inserts for maximum wear resistance;

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.
