The ZOOMLION KSD25 Dry-Wet Horizontally directional Drill is the first drill which drills through hard rock without a bentonite and mud pump. Its pneumatic percussive technology has not only solved the problem of mud pollution, but also has increased its efficiency 40% higher than a normal drill. Additionally, its cost is also much lower, and therefore, it has been considered as a most efficient solution for complicated stratum (including pebble and gravel, backfill and rock).
