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.
