Sandvik RD520 is a hydraulic percussive rock drill with independent reversible rotation and low profile height. Known for its hydraulic efficiency and high penetration rate, Sandvik 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 a stabilizer to control contact between the drill bit and rock. The stabilizer also dampens recoil impulses from rock and lengthens the lifetime of drilling tools.
