Product APPLICATION:

DTH hammers and bits are widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering,

water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering.it has the advantage of high flatness, smooth hole wall,high rigid of drill rod and hammer,independent

of high axial thrust, no limit of drilling depth, low cost of devices and easiness to maintain.

Product Description:

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 conventional DTH hammers:

3:Simple structure,reliable parts,long life,easy and low cost maintenance

4:Low air and oil consumption,the oil consumption is about 10% lower than the conventional DTH hammers.
