PDC cutters are also named Polycrystalline Diamond Compact cutters, PDC bits, or PDC inserts. They consist of a Polycrystalline Diamond layer and a carbide substrate. The diamond is grown directly on the carbide substrate.
PDC Cutters are made from tungsten carbide substrate and synthetic diamond grit. It is manufactured using a combination of high temperature and high pressure with a catalyst of cobalt alloy to help bond diamond and carbide during the sintering process. During the cooling process, the tungsten carbide shrinks at a rate 2.5 times faster than the diamond, which tightly combines Diamond and Tungsten Carbide together to form a PDC Cutter.
Since PDC Cutters consist of diamond grit and tungsten carbide substrate, it combines the advantages of both materials: high abrasion resistance, high impact resistance, and high thermal stability.
Currently, PDC Cutters are widely applied to oilfield drilling, gas and geological exploration, coal mining, and many other drilling and milling applications. They are used in tools such as:
