5inch High Air Pressure Down The Hole DTH Drilling Rock Hammer For Mining

5inch High Air Pressure Down The Hole DTH Drilling Rock Hammer For Mining

5inch High Air Pressure Down The Hole DTH Drilling Rock Hammer for Mining, DTH hammer is a percussion system driving a piston inside hammer body with up and donw motion by compressed air and transmitting an intensive percussion energy to the bit to enable the drilling by crushing the rock. Drilling method by DTH hammer exerts high drilling performance especially for drilling hard rock and contributes for shortening work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, etc.
