DFR5
The Doofor DFR5 is a new generation high-power, high-frequency rock drill specially designed for underground drilling. The reduced overhead and versatile rotation motor positioning make the rock drill suitable for tunnelling and mining.
DFR5 is less sensitive to return line pressure, which makes it a good rock drill also for excavator attachements, where long hoses add to back pressure. Higher pressure combined with lower hydraulic oil flow enhance the drifters energy efficiency.
Robust gearbox, bronze bearing surfaces along with improved mounting points add to durability in demanding underground mining conditions.
