RDX5
HYDRAULIC ROCK DRILL
TECHNICAL SPECIFICATION
Sandvik RDX5 is a robust rock drill for heavy duty rock MAIN DIMENSIONS
drilling. It is designed for face and long hole drilling, also Hole diameter drilling 43 - 64 mm
used in rock bolting. RDX5 is designed to perform even Hole diameter reaming 76 - 127 mm
in the harshest conditions. Power class 20 kW
Percussion rate 67 Hz
RDX5 rock drill is known for its exceptional durability. The
Operating pressure
robustness is achieved by less pressurized seams and Percussion 120 - 220 bar
simple design with only two moving parts. The design Rotation (max.) 175 bar
of the rock drill enhances hydraulic efficiency while Rotation motor type OMS 80, OMS 125 or OMS 160
lessening wear on the parts. R32, R39 or Hex 35 mm drifter rods,
Drill steels
MF-rods highly recommended
RDX5 has excellent serviceability through modular Shanks 45 mm / T38 / R32 / T35 / R38 / T45
construction and visual wear indicators. It also has an Weight 210 kg
integrated carriage for ease of service.
Shank lubrication drain is led to feed surfaces to reduce
lubrication fume, creating a more comfortable working
environment.
