PDC bit is an integral drill which hasnt activity components. The structure of PDC bit is very simple, it generally includes drill body, cutting teeth, nozzle and junk slot, etc. Detailed description 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.
