Drilling in driving rifts and tunnels with a small cross section? Then a water-flushed pusher leg will make all the difference.
We revolutionized underground rock drilling, by what is now called the "Swedish method" - A combination of lighter tools and pusher legs, which allowed one man to do the work of two.
Silencers and vibration dampening systems allow you to work comfortably.
Make every liter of air count. Every pneumatic underground rock drill combines light weight, high torque and high impact energy.
Pneumatic tools for raise driving, bolting and screening.
