RockSmith's DTH Hammer Range

RockSmith's Down The Hole Hammers

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.

Rocksmith are proud to offer top quality DTH hammers. Our DTH Hammers are state-of-the-art hammers perform exceptionally well with increased power for more efficient drilling and have been tried and tested in the harshest of rock conditions.

Rocksmith provides spare parts for all our Hammers.

To help ease the selection process we have categorised our DTH hammers based on hole size dimensions.
