MST250 Stoper Drill
The MST250 Stoper Drill configuration helps miners to drill vertically upside-down with minimum effort and risk to ensure drilling in uncompromised orientations to maintain desired productivity. The stopper leg attachment does not affect the high penetration rate and still allows the drill to achieve high torque at low air pressures. The stoper leg configuration ensures the safety of the operator and increases the life of the drill simultaneously. The ergonomically designed stoper leg has a push button to retract the stoper leg and an adjustable motorcycle control feed.
