          Features Spiral five blades design, the rational allocation of different functions big size cutters, so that the PDC bit get high ROP in soft and sticky soft formations. High quality arc PDC cutter gauge, reduce the abrasion of rock on the bit’s body, increase wear resistance and stability of the drill gauge. Brazing high wear resistance PDC cutters at specific angle, when resistance during trip-out and back reaming in easy shrinking interval, it can effectively remove the obstacles, protect the bit body from harm. The surface of the blade weld high-performance wear-resistant materials, improve bit’s wear resistance and erosion resistance.
          Application Soft formation with sticky layers and low compressive strength. Such as Clay, Marl, Lignite, Shale, Sandstone and so on.
