Hydraulic Forging DTH Hammer
1.Lower energy consumption
2.Higher impact frequency
3.Easy and cheap maintenance
4.Long life

Hydraulic Forging DTH Hammer(SD8):

1. 10 years manufacturing experience;

2. Certificate: ISO9001:2008

3. Material: Carbide

It is a kind of high air pressure DTH Hammer without footvalve, our newest design. It is also one of the most advanced DTH Hammers in the world.

It has the following advantages:

1. Out of the trouble of foot valve fracture and expansion and contraction.

2. Lower energy consumption and higher impact frequency. The drilling speed is 15%-30% higher than the one with foot valve.

3. Simple structure, reliable parts, long life, easy and cheap maintenance.

4. Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.
