Designed to endure demanding environments

Doofor hydraulic rock drills

Doofor Inc. designs and manufactures hydraulic rock drifters and original Doofor spare parts. 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 and other options. Technical data given is for a typical setup.
