Dimensional Stone Drills

Heavy range for industrial use

When you see the DSI designation on a drill, you'll know it's made for bigger operations.  DSI stands for Dimensional Stone Industry and these well-proven pneumatic rock drills can be mounted on a drill column to make you really productive.

The BBD model can drill holes up to 27-41mm in diameter and they come equipped with an H22 chuck and air flushing as standard.  You can get water flushing as an option and the mains can be equipped with both cable or chain feeds

  • Cut noise - The silencer can reduce the noise by up to 5 dB(A), which is perceived as a 50% improvement of noise levels to the human ear.
  • Rotation that lasts - The powerful rifle bar rotation mechanism is dimensioned to handle industrial demands.
  • Recipe for productivity - The BBD 94DSI weights 57 pounds, has great impact energy and can handle low air pressures
  • When to use - Short stroke and high impact rate makes it ideal for soft rock
  • High efficiency - A large piston diameter makes the drill efficient even at low air pressure.
