Hydraulic rock drill DF540L-EXT-2M

Hole diameter [mm]


Power class [kW]


Doofor DF540L-EXT-2M is a hydraulic rock drill in the 14kW size class and it has a hydraulic extractor function and two OMS-type rotation motors. Motor displacement can vary between 80 cm³ to 160 cm³. Two rotation motors offer a consistent torque and yet a high rotation speed necessary for successful high-frequency rock drilling. It is designed for general excavations, underground production drilling and bolting.

The DF540L-EXT-2M has a low overhead, which makes it a good underground and limited access drifter and a patented percussion valve for optimal flow-power ratio.

Flushing media can be water or air. The rock drill can be equipped with male R32, R38 and T38 shank adapters (striker bars).
