The MHD1838. High productivity and superior drill steel economy are produced by an effective hydraulic dual-damping system with a floating adaptor. High torque and great speed control are guaranteed by a strong stepless variable and reversible rotating motor. Pressurised, lubricated mating surfaces and side bolts, as well as separate lubrication of the front head and driver, boost productivity while reducing downtime.
