China Ql60 152mm 165mm 178mm 203mm DTH Bits Atlas Copco Ql Series Button Bits for Australia Mining Drilling

DTH(Down the Hole) hammer is used for drilling holes through a wide range of rock types, the variety of which continues to extend well beyond the original conception of early blast hole drilling.

Down-the-Hole refers to where the hammer action occurs when compared to drifter hammers, which hammer on top of the drill string. The DTH hammer piston always makes direct contact with the drill bit and there is generally no loss of transmitted energy as the hammer drills deeper, as is the case with drifter (top hammer) rigs.

Roschen offers a wide range of DTH hammers suitable for a variety of drilling operations. Our Down the Hole hammers provide the most versatile and cost effective rock drilling method.
We are a leading manufacturer of rock drilling tools, like DTH hammers and bits, DTH drill pipes, RC hammers and bits, tophammer button bits, coupling, cross bits, drill rods located in Germany, China(joint-venture).
