The PDC bit is the new type of bit with the characteristics of high
wear resistance, high impact resistance, antiramps,antiballing,
high drilling rate. It has been proved by field using that have
characteristics of high speed, fast headway,long lifecycle,steady
working,less accident in well,best quality of well body. The PDC
bits that we research and development have reached more than
30,which can satisfy the requirements of different strata.
