Product advantages:
1.Valveless air distribution. More reliable.
2.Simple design of the piston. Long life span.
3.More efficient energy transfer, faster drilling speed, lower air and oil consumption.
4.Fewer internal parts, simple structure, less failure and easier to maintain because all the parts are heat treated.
5. Easy to disassemble because the stop sub, the drive chuck and the external cylinder are connected by multiple steps thread.
Application:
It is widely used in open pit mining, tunneling, quarrying, transportation construction,engineering, earth-rock excavation, water wells, pile foundation, and civil engineering project etc.
Sollroc is the professional DTH drill bits supplier! After many years experience we provide the worldwide customers ideal DTH drill bits. Optimized designs improve the drilling efficiency.
