Description
Atlas Copco Pneumatic Underground Rock Drill 31KG BBD 94WS
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.
