Brief introduction of PDC:

Polycrystalline Diamond Compacts 


• PDC cutters are also named Polycrystalline Diamond Compact cutters, PDC bits, PDC inserts. PDC cutter is a kind       of super hard material.

• The PDC cutters consist of a Polycrystalline Diamond layer and carbide substrate. The diamond layer and substrate    are sintered under ultra-high pressure and ultra-high temperature. In short, we say it’s HTHP Press.

• The diamond is grown on the carbide substrate, not coated. They are firmly combined. 



Main Advantages 

• High density (low porosity) 
• High compositional & structural homogeneity 
• Excellent bonding between diamond particles 
• High wear resistance 
• High impact resistance 
• High thermal stability 
• Optimized interface between diamond and tungsten-carbide layers for excellent binding 

The working life of the PDC cutters is increased by more than 6 times

The production efficiency is increased by more than 20%.

Make the target for one time completed drilling become possible

Reduce the frequency of replacement of drilling bits and the labor intensity of workers.
