Diamond Edge Pdc Drill Bits With Pdc Cutters Made In China For Oilfield
PDC drill bits are produced with a tungsten carbide crown imparting a much superior wear resistance than equivalent steel headed bits. The PDC cutters are mounted on the bit face and gauge area which assists in reducing gauge wear in abrasive formations.
These drill bits are used in soft to medium formations typically sands, soft lime stones and some dolomites with medium to low compressive strengths.
