High-performance hydraulic rock drill
Doofor DF560L-EXT-2M is a high-frequency hydraulic rock drill specially designed for ground stabilization and general excavations. The DF560L-EXT-2M has very low overhead and two OMS-series hydraulic rotation motors for extra torque. High torque combined with high rotation speed offers benefits in fissured rock or mixed soil conditions. The extractor of the EXT-version is ideal for back hammering to break drill strings and for removing stuck drill steels from the rock.
The rock drill can be equipped with shank adapters (striker bars) R38, T38, and T45.
