Forging Processing DTH Hammer High Performance For Water Well Drilling Equipment
4 inch Stone Quarrying Down The Hole DTH Hammer for Deep Well Drilling and 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

Advantages of high air pressure DTH hammers:
1) Non-Blocking:Our Down the hole hammers are proved to ensure extremely low rate of blocking during it works.
2) High Efficiency:The well drilling equipment carries with larger power of impact frequency and torque, thus ensuring faster penetration. Compared with others, the efficiency can be improved 10%.
3) Longer Service Life:All surfaces of the DTH hammer and bits are treated by anti-friction and intensified technology. When used in deep-hole drilling works, it can reach at 5000 meters or more.
4) Excellent Cleaning Effect: This DTH tool has large air output, which specially designed for water well users and enables it to flush out cuttings in deep hole drilling works.
