PDC cutter, also named Polycrystalline Diamond Compact cutter, which is a kind of super-hard material.
PDC cutter is a disk made of polycrystalline diamond, synthesized by sintering diamond grit with a catalyst under high pressure and temperature to withstand the extreme abrasion impact and heat that comes from drilling through rock.
Polycrystalline diamonds possess extreme hardness-similar to that of natural diamond, the world's hardest naturally occurring substance--with the strength and durability of tungsten carbide.
The PDC cutter has the features of good wear-resistance, impact resistance and good thermal stability, which is widely used for mining, geological exploration, oil and gas rilling, stone processing and ground grinding.
