High Air DTH Hammer1.efficient energy transfer2.faster drilling speed3.lower oil consumption4.longer life,less failure
It has the following advantages:
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 because all the parts are heat treated.
5 Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
