Down The Hole DTH Hammer M60 165mm Rock Drilling Button Bits/ Drill Bits
Product description
DTH hammer drilling is the industry standard for the rapid drilling of boreholes for a variety of uses such as water wells, blasting and sub-surface void locations.
With the increased availability of efficient high pressure compressors operating up to 25 bar (in some cases with even higher pressures) boreholes can be drilled in even the hardest rocks much quicker than using conventional tricone rock roller drilling techniques.

1. This face has been designed to offer high penetration rate in soft rock such as shale, limestone etc
2. They are recognized for having excellent capability for drilling into moderately consolidated rock conditions
Product application
At present, DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering.
DTH is one of the most efficient ways of drilling rock, using a rapid hammer action to break the rock into sizeable chips which are then evacuated from the bore hole by the air exhausted from the DTH Hammer. The technique provides fast drilling of accurately aligned, straight and clean holes in most ground conditions.
