DF560L-BLTF-2M
Doofor DF560L-BLTF-2M is a hydraulic rock drill equipped with two rotation motors, completely separated flushing box and hermetic rotation mechanism for demanding underground conditions. 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. Motor fitting direction can be specified (up, down or side).
Doofor DF560L-BLTF-2M is a high-frequency hydraulic rock drill specially designed for grouting, ground stabilization and general excavations. The drifter has a very low overhead, only 84 mm from the drill center line.
The rock drill has a completely separated, non-corrosive flushing box. Flushing media can be water, air or grout (limitations apply). The rock drill can be equipped with female shank adapters (striker bars) R32, R38, T38, and Titan T40F.
Optimal maximum hole diameter for the DF560L-BLTF-2M is 89 mm.
