PDC Drill Bit:


This PDC drill bit is also used in coal exploration from soft to medium forms as a base drilling.

Product Advantages:

PDC anchor shank drill bit is made by with premium PDC cutter,with high abrasion resistance,impact resistance and drilling efficiency. Their life is 10—30 times of alloy bits,usually the blade has 2 or 3 wings.

high quality cutters and advanced brazing technology, so the anchor shank drill bits have high impact resistance and stable performance, can be applied to rock formation of f ≤12,like gravel, granite, limestone, etc. Ourdiameter is from 25mm to 270mm, any special design is available upon customers’ request.


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.
