DF560L-BLT-2M

High-performance hydraulic rock drill

Doofor DF560L-BLT-2M is a hydraulic rock drill equipped with two rotation motors and multiple sealing and hermetic rotation mechanism for demanding underground conditions. Two rotation motors enable continuous, high torque while maintaining high rotation speed. The stainless steel BLT-flushing head can be turned upside down. Rotation motor can be placed on the left or right. Motor fitting direction can be specified (up, down or side).

Doofor DF560L-BLT-2M is a high-frequency hydraulic rock drill specially designed for ground stablilization and general excavations. The drifter has a very low overhead, 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 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 89mm.
