Portable Pneumatic Flame-proof Drilling Machine
Used in drilling holes for exploring, discharging gas and water in coal lane and coal-rock lane. With reverse rotated action.
Used in drilling holes for exploring, discharging gas and water in coal lane and coal-rock lane.
With reverse rotated action, it can take out the drill rod and bit easily. It is also the ideal equipment instead of electric machine for water an gas discharging under mine.
