High-performance hydraulic rock drill
Doofor DF540L-2M is a hydraulic drifter in the 14kW size class with two OMS-type rotation motors and a standard flushing head. The rock drill is designed for general excavations and ground stabilisation. The DF540L-2M has a low overhead and two rotation motors. Two rotation motors offer a stable, high torque while offering a high rotation speed necessary for patented high frequency percussion.
Flushing media can be water or air or air-water -mist. Available shank adapters are R32, T35, R38, T38 and T45.
Optimal maximum hole diameter for the DF540L-2M is 64mm.
