Designed for higher ROP in drilling deep and medium-hard rocks,  PDC drill bits always drills from ground to bottom directly without changing another drill bit, it saves huge drilling and labor cost.


Different from tricone bits, the PDC drill bits need lower WOB but higher RPM, so it always works with mud motor to get high rotating speed. 


Quality of PDC drill bits mainly depends on quality of  PDC cutters, we provide unique solution according to specific requirement and detailed geological information.
