The Doofor DF560L-BLTF-2M Rock Drill is a hydraulic rock drill equipped with two rotation motors and a completely separated flushing box 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 BLTF-flushing head can be turned in 90 degree steps.
The Motor fitting direction can be specified to either up, down or side placement.
The Doofor DF560L-BLTF-2M is a specially designed for Grouting, Ground Stabilisation and General Excavations.
The DF560L-BLTF-2M drifter has a very low overhead height of only 84mm from the drill center line.
