PDC cutter:

Introduction of PDC 

PDC is sintered of diamond micro-powder and tungsten carbide substrate under high temperature and pressure. It has great wear resistance like diamond, as well as the high impact resistance like tungsten carbide, what’s made it as the best drill bits' insert. Reinforced PDC has higher dense diamond powder, clawing tungsten carbide substrate made the two layers solid as a whole one. 

Application

With high hardness, abrasion resistance and impact resistance, they are widely used for oil/gas drill bits, rock drill and coal mining drill bits, and also can be used for diamond tools for cutting, grinding, polishing.

Advantages

1.Optimized interface between diamond and tungsten carbide layers for excellent binding.

2.Penetration rate is improved by using high quality diamond powder which is self-sharpening.

3. Cutters can drill a precise round hole and reduce bit whirl as its force balanced design.

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

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

6.Good thermal stability.
