          Features Double rows six blades design, rational allocation of high quality medium size PDC cutters. The maximum local cutters equivalent density, improve the offensive and abrasive resistance of the bit. 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 PDC cutters at the cutting face of the gauge, increase the gauge’s abrasion resistance and impact resistance. Ensure the drill hole diameter, and improve the quality of the hole. The surface of the blade weld high-performance wear-resistant materials, improve bit’s wear resistance and erosion resistance.
          Application Medium hard formation with high compressive strength and abrasive, such as Limestone, Anhydrite, Dolomite and so on.
