COP84 (DHD380) 203-305mm high air pressure energy saving DTH Drill Bits
The use of high quality steel and hard alloy as raw materials, through a special heat treatment process, ball tooth bit can reach under the hardness strong rock excavation, and to reduce the energy loss in the transmission process, tooth uniform force is not easy to drop off the teeth and teeth, so that impact the energy to focus on the rock to reach the purpose of high efficiency driving.
The alloy steel is very strong and has long service life.
Strong torque, head design rich for different geological needs.
Standard of work size. Reduce wear and tear to screws and extend service life.
Different sizes and sizes. Meet the needs of different airlines.
