Drills, stopers and pusher legs

BBC 16W underground pneumatic rock drill

BBC 34W pneumatic underground rock drill

Built-in water flushing

Drilling in driving rifts and tunnels with a small cross section? Then a water-flushed pusher leg will make all the difference.

The Swedish method

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.

Comfortable drilling

Silencers and vibration dampening systems allow you to work comfortably.

A tool for every rock drilling job

Make every liter of air count. Every pneumatic underground rock drill combines light weight, high torque and high impact energy.
