RMT 46WR-8 [BBD 46WR-8]

Because of the large diameter of the piston these drills are equally efficient with low air pressure. It comes with robust ratchet wheel rotation mechanism, short stroke and good penetration rates in soft and medium hard rock. The WR version with clockwise rotation can be used for buts tightening when roof bolting. The drills are suitable for production drilling, raise driving and bolting.
