Water Well Drilling 6'' QL60 Hammer DTH QL 60 High Pressure Down The Hole Drilling DTH Hammers

STAROCKDRILL STR QL 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 • Premium material, fine CNC and heat-treatment manufacturing processes and optimized design; • Good stability and reliability; • High impact frequency; • Lowered compressed air consumption; • Long lifespan High Air pressure up to 35 bar DTH Hammer Advantages: 1.Valveless air distribution, more reliable; 2.Piston with simple but compact design, long life; 3.More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption. 4.Fewer internal parts, simple structure, longer life, less failure and easier to maintain, with the all heat treated parts; 5.Easy to disassemble, thanks for the top sub, drive chuck and external cylinder all are connected by multi-step thread.
