QL5 5inch water well hammer,high air pressure dth hammer for water well and rock drilling
DTH Hammer is a percussion system driving a piston inside hammer body with up and down 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.
DTH hammers are used for mine, quarry, road construction for the drilling and blasting work, water well drilling, slope protection, anchoring, etc.
