R32 Drill Bits are ideal for medium to hard ground, they are recognized by their characteristic raised buttons and grooved chipways and flushing holes on the face.
GMD rock tools for top hammer drilling are designed to transmit intensive impact energy into the rock with the least possible loss of energy. The result is good rock breakage, high penetration rates and high productivity. This, together with optimal hole quality, great reliability and long service life, gives the best possible blasting results, outstanding drill-steel economy and low total cost.
