The DTH is the abbreviation of Down The Hole and sometimes it is also called RAB in some markets, then the RAB is short for Rotary Air Blasting

SINODRILLS GSE DHD-N DTH Hammers


DTH (down-the-hole) drilling involves a drilling hammer at the bottom of a drill string, the hammer is powered by compressed air transmitted via drilling rod to drive piston and produce impact power, which is then delivered into rocks for drilling and crushing. DTH drilling can be applied in mining, quarrying, water well drilling, foundation piling, etc. DTH hammer uses compressed air to produce impact power, thus to drive drill bits to crush rocks.


Features
