Product Description
High Air Pressure DHD350 (HD55/COP54) with Footvalve and DHD350A Without Footvalve DTH Hammer Button Bit for Mining Drilling Rigs
1, valveless air distribution. More reliable.
2, simple design of the piston, long life.
3, More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption.
4, fewer internal parts, simple structure, longer life, less failure and easier to maintain becayse all the parts are heat treated.
5, It is easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
