Down The Hole Hammers (DTH) are mostly the preferred tooling for the blast hole drilling team, its fast and efficient while the rig size is much smaller that the rigs which use weight on the bit to cut the rock.

Any professional driller knows that it is important to choose the right tool as there are many sizes from 3” to 12” hole diameter. Kobald Mining Services are happy to offer blast hole hammers providing you the longest possible service life and also good performance with drilling pattern optimization. The hammer works by turning slowly while a piston sticks the bit many times a minute which in turn fractures the rock and the air flow lifts the fracture rock to the surface. In such a way, you obtain a well-balanced fragmentation, improved productivity and better safety conditions for the operator!
