Blast Hole Drill Rig Rockmaster RM615A

Blast Hole Drill Rig Rockmaster RM615A
The newest addition to our Rockmaster series is the RM615A, a brand new second generation blast hole drilling rig. Our Rockmaster series, which is already known for its good reputation, excellent maneuverability and overall reliability, only get's better with the addition of this drill rig.
We are confident that the RM615A going to provide a better drilling experience because of it's improved performance and maneuverability. Some of the new improvements made for our second generation Rockmaster drill rig include:

Build Your Rig




Better efficiency: Allows a very low fuel consumption.
Better ground clearance: Lower of 14” but we kept the ground clearance of 17”.
Better rear clearance: The hose reel and the winch is partially inside the canopy for more rear clearance.
More traction: the ground effort is improved of 50%.
Bigger pull back force: 21000 lbs.
Stronger and practical carrousel: much stronger and the pipe length is now std for 5m /16’-4” instead of 15’.
Improved rotary head: in fact we go with RH900 of EURODRILL because is simply the best.
