QJ 15 Hand hold and Air leg Rock Drill

The rock drill has hand-hold and air-leg functions and has characteristic of low weight, reasonable structure, handy use and little air consumption. It is mainly used in small mines、small water conservancy、prospecting and mining、highway traffic and defence project facility. It is also suitable for drilling and blasting under various of rocks. When it is uesed to hand hold,it can blast blasthole downward. When it is matched with Model FT80 air leg ,it can drill blasthole at any direction angles. During drilling ,when it match with drill、drill bit and other drill tools,drill bit diameter is 32-38mm,blast hole depth is ≤4m
