Zhuzhou Rock Drilling Tool DTH Drill Bit High Pressure Tungsten Carbide Mining Rock
Description
The DTH drill bit is matched with the DTH impactor. The drilling operation is carried out by spline and impactor. Using high quality steel and cemented carbide as raw materials, through special heat treatment process, the ball-tooth bit can meet the requirements of rock excavation with strong hardness, and can minimize the loss in the process of energy transmission, even tooth-fixing force is not easy to lose teeth and tooth-shedding, so that impact energy can be achieved. Concentrate on the rock so as to achieve the goal of efficient tunneling.
