Product Description
What is DTH hammer ?DTH Hammer has a wide range of use in all kinds of hard and abrasive rocks,follwing features:
1.New products designed based on mining condition, improved by advanced technology.
2.International High-Standerd materials with advanced process guaranteed quality.
3.Faster drilling rate.
4.Enhaced hardness to expand the life of hammer, and lower the using cost.
5.Low consumption of electricity with big impact force.
6.Good transmission of power.
7.The modern theory is adopted in the structural design, which makes the stress wave duration longer, the stress amplitudeis lower, and the piston life is long.

1.Avoid the problem happens on foot valve. Fracture,expansion and contraction.
2.Lower air comsumption and higher impact frequency.15-30%higher drilling efficiency than the bit with foot valve.
3.Simpler structure and less spare parts, makes easier & cheaper maintenance.
4.Heat-hardened spare parts,makes longer serving life and less problem.
5.Thread connection for top sub and drive chuck,makes easier disassembly.
