high pressure DTH hammer


Features:

1. DHD hammer is with the optimum valve size, chamber design and air tightness, the air consumption of the system can be reduced by more than 10% with less fuel consumption.

2. The impact frequency is faster than that of the same period, and the drilling speed is faster more than 15%.

3. Applying advanced heat treatment technology, the surface of hammer is strengthened, and the wear resistance is better more than 15%.


Advantages:
1. High hammer impact power and high drill hole efficiency.

2. The DHD Hammer is easy to disassemble and maintain.

3. There is no tail pipe (nylon pipe) in the bit, in order to eliminate the thermal expansion, cold shrinkage and damage of the bit in operation.

Applications 

The Down-The-Hole hammer is designed to increase efficiency in drilling as well as conventional drilling. The presented series can be used for multiple purposes such as the geotechnical, mining, quarrying, geothermal, mineral, underground, and other exploration drilling. We are dth hammer manufacturer and dth hammer bits manufacturer, our products quality can compare with sandvik dth hammer/ atlas dth hammer / halco dth hammer. We are suppliers and many dth hammer distributors they buy from us and sale our ROSCHEN products. We can also provide related products, ODEX system, symmetric systems, slide block drilling systems, etc and DTH drilling pipes for various thread API REG, API IF, BECO, dth hammer lubricator , dth hammer piston , dth hammer piles , dth hammer spare parts ,etc.
