Rebound Energy Recovery Valve

  • Recycles rebounding shock waves, adding energy to next blow

Reverse Percussion Option

  • Full anti-jamming when drilling through fractured rock

Drilling Automatics -- Rock Reader Technology

  • Drifter senses varying material hardness. Automatically adjusts:
    - Feed pressure
    - Rotation
    - Percussion pressure
    - Feed speed forward and backwards

Other options include:

  • Choice of feed sizes available in 24 foot and 14 foot configurations

As a drill steel advances it encounters zones of varying material hardness. Each such zone requires an adjustment in drilling technique for optimum production and equipment safety. Montabert's world-renowned drifters and drill control technology sense rock conditions as the hole advances, and automatically make the necessary corrections to rotation, feed and percussion pressure, and feed speed forward and backward
