PDC Cutter (Polycrystalline Diamond Compact ) is composed of polycrystalline diamond(PCD) and cemented carbide substrate, which is a kind of super-hard composite produced under ultra-high pressure and ultra-high temperature. It integrates the advantages of diamond and tungsten carbide.
Main Feature:
1. Excellent wear ability and impact resistance
2. Long useful life, high efficiency, and good cost performance
3. The useful life of the PDC bit is 4~5 times that of the diamond bit, 10 times that of the tungsten carbide bit
Application:
PDC cutter(Polycrystalline Diamond Compact) is widely used for making tools applied in the fields of oil and gas drilling, geology exploring, coalfield mining, and the mechanical processing industry.
1, Standard:
Standard PDC adopts a new flat, slotted junction plane, the thickness of the diamond layer is from 0.8-2.5mm according to the client’s requirement. They are widely used for Engineering and geological purposes.

2, Sphere shape:
Sphere-shaped PDC has more excellent shock-resistance toughness (ballistic work is equal to that of hard alloy) and it can be applied to percussion drilling, medium and small drill bits, oil roller bits, down-the-hole drill bits geothermal drilling, etc.
