Sollroc 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,water well drilling, mining, landslide prevention work, quarrying services, marine civil work, etc.
1. More efficient energy transfer.
2. Faster drilling speed, 15%-30% higher than others.
3. Lower air consumption and lower oil consumption. oil consumption is about 10% lower than others
4. Direct factory price.
