Polycrystalline Diamond Compact bit, known as PDC bit, is made up of small cutting blocks which consist of polycrystalline diamond thin round sheet inserted onto the drill bit body. It is suitable for soft to medium-hard formations.
PDC bit is an integral drill which hasn’t activity components. The structure of PDC bit is very simple, it generally includes drill body, cutting teeth, nozzle and junk slot, etc.
PDC bit can be divided into two types: steel body and tungsten carbide matrix. The surface of steel body PDC bit is easily to be eroded. While tungsten carbide matrix PDC bit is difficult to eroded.
Selfsharpening of PDC tooth is very good. Polycrystalline diamond grains shed in the process of cutting the rock and form new blade grain to update the self-sharpening. In addition, tungsten carbide substrate forming sharp cutting edge after wearing, exhibiting good anti-impact performance and providing flexibility for diamond.
Function ＆Advantage:
1、suitable for soft to medium-hard formations
2、Operating in cutting principle, cutting rock in low energy consumption
3、PDC cutters have the characteristics of super hardness, wear resistance and self-sharpening
4、PDC bit belongs to fixed tooth bit, hasn’t active components and work in high reliability
