The Doofor DF560L-BLTG-2M Rock Drill is a Hydraulic Rock Drill equipped with two rotation motors and a Hermetic Rotation Mechanism for demanding Underground Drilling conditions. The two rotation motors enable continuous, high torque while maintaining high rotation speed.
The stainless steel Doofor BLT-flushing head can be turned upside down.
The rotation motor can be placed on the left or right. Motor fitting direction can be specified (up, down or side).
Doofor DF560L-BLTG-2M is a high-frequency Hydraulic Rock Drill specially designed for ground stabilisation and general excavations.
The Doofor drifter has a very low overhead height of only 84mm from the drill center line.
The Rock Drill has a separated, non-corrosive flushing box.
Flushing media can be water, air or grout (limitations apply).
The Doofor Rock Drill can be equipped with shank adapters (striker bars) R32, R38, T38, and T45.
Optimal maximum hole diameter for the DF560L-BLT-2M is 89 mm.
