It is proven by testing and using in many job sites for varies rock conditions. It is used for varies applications, including mining, exploration, water well, geothermal, construction drilling and civil engineering, especially for mining.

Features

1、Valveless air distribution ensures smooth working.

2、Piston design and harden wear part ensure strong wear-resistance.

3、Minimize the energy loss, high penetration, lower air and oil consumption.

4、Fewer internal parts minimize the maintain and replace the part requirements.
