Description
SINODRILLS GSE SD DTH Hammer
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 of GSE SD DTH Hammer
• 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
Applications of GSE SD DTH Hammer
Mining, quarrying, water well drilling, geothermal well drilling, foundation piling, etc.
