Doofor hydraulic rock drills
Doofor Inc. designs and manufactures hydraulic rock drills, also known as drifters and top-hammers. Doofor provides original spare parts for prolonged life-time. We use the strong Nordic know-how of mining and construction machine building and the superb ability for demanding, high precision component manufacturing. Doofor rock drills have been installed in a variety of new drill rigs, drill attachments, bolting equipment, rebuilds, and retrofits.
Doofor rock drills utilize Doofor-developed high-frequency technology, which allows fast penetration speed with less strike force. Drilling speed is enhanced with Doofor’s trapezoid-shaped piston design which improves the movement of the blow impulse straight to the drill bit. Rock drills can be equipped with different shank adapters, motor sizes, flushing media and other requirements.
