The rock drill has a hand-hold and air-leg funtions and has characteristic of low weight,reasonable structer,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 used to hand hold,it can blast blasthole downward.When it is matched with Modle FT80 air leg,it can drill blasthole at any direction angles.During drilling,when it match with drill,drill bit and other drill tools,drlii bit diameter is 32-38mm,blast hole depth is less than 4m.
