|Rock drills utilize a Doofor developed high frequency technology which allows fast penetration speed with less strike force. This minimizes stress caused to the drill tools and maximizes drill hole straightness.
The trapezoid piston – also innovated by Doofor – also attributes to the drill speed as it is improving the movement of the strike impulse in the drill rod.
The DF600S and DF700S rock drills also have a double dampening system to minimize stress to the shank adapter or striker bar.
Doofor rock drills always have a 12 month guarantee against manufacturing faults. Doofor also offers a cost effective drill update possibility when maintaining the rock drill.
Also a possibility to use a well designed feed beam profile of aluminum alloy. With the aluminum profile our customers can have a feed beam suitable for light drilling applications without the need to invest in aluminum mold costs. Aluminum profile can be used with rock drills up to the weight of 75kg.
