A PDC consists of a polycrystalline diamond layer and a cemented carbide substrate. It is made by sintering fine diamond powder and cemented carbide substrate together at a high atmospheric pressure and temperature (about 60,000atms and 1,400-1,500℃). It is suitable for drill bits (PDC drill bits) working on various strata.  Due to the complete D-D bindings among the diamond grains at the polycrystalline diamond layer, the diamond layer has high strength, hardness, and wear resistance and also shows excellent self-sharpening performance.

 

In its operation, a PDC drill bit crushes rocks by cutting and is more effective than a roller cone bit crushing rocks or an impregnated diamond bit ploughing and grinding rocks. The polycrystalline diamond layer and the cemented carbide substrate are combined in a tooth structure, thus consolidating the two layers and ensuring better impact resistance of the drill bit.
