Sandvik RD520 hydraulic rock drill is designed for face drilling on Sandvik mine development and tunneling jumbos. It is also suitable for bolt hole, exploration and injection hole drilling.
Sandvik RD520 is a hydraulic percussive rock drill with independent reversible rotation and low profile height. It is known of its hydraulic efficiency and high penetration rate. RD520 has excellent serviceability through modular construction and visual wear indicators.
Robustness is achieved by having only few pressurized seams between functional modules. The rock drill is equipped with stabilizer to control contact between drill bit and rock. The stabilizer also dampens recoil impulses from rock and lengthens the lifetime of drilling tools.
