Blast HOLE drilling rigs

Blasting Drilling Rig


Drilling Supply blast-hole drilling rigs are designed to suit all your drilling needs ranging from civil and construction Blast Hole Drill Rig works to heavy-duty mining projects.  Our rigs include crawler-mounted diesel engine and electric engine models.

All our blast hole models feature a sturdy, well designed chassis. Its structure is the key element for the durability of this rig which provides superior endurance and lower maintenance cost.

Traction: Even on the roughest terrains, the strong undercarriage track frame, which features independent oscillation, will allow smooth drilling and improved stability.

Feed Mast: From its unique conception, the Rockmaster feed system provides superior rigidity resulting in higher drilling accuracy ranging from 3 in (73 mm) to 8 3/4 in (222 mm). The ultra rigid feed beam has been specifically conceived to provide long lasting drilling service.
