Down-Hole Hammer Air-Powered with Percussive Operation for Hydraulic Drills

A down-hole hammer is a percussion hammer drill. In this type of hammer the piston applying repeated percussive pressure is in direct contact with the bit. As the name implies, this hammer works 'down the hole'. The hammer and the bit are located at the end of the drill string. One of the main advantages of the DTH hammer is that the drilling rate is not affected very much by the length or depth of the hole. DTH Hammers are well suited for drilling into medium hard to hard rock. They are especially well suited for drilling into fractured rock. They are extensively used in mining, quarrying, civil engineering and water well drilling industries.

Advantage:

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.
