Underground Pneumatic Rock Drill
Every pneumatic underground rock drill combines light weight, high torque and high impact energy.
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 psher legs, which alloed one man to do the work of two.
Comfortable drilling - Silencers and vibration dampening ystems allow you to work comfortably.
