THE DRILLER'S CHOICE

Integrated Ring-Bit Systems

Integrated ring-bit systems are designed for drilling straight piles through boulders, rock layers, and even into inclined bed rock.

The heavy-duty ring-bit is integrated in the casing shoe, making it safe to drill in loose ground and water.

Primary applications:
  • End-bearing piles including micro-piling
  • Pilings with sacrificed casings, which have
    no
    large ID ring-bit requirements
  • Slope stabilisation
  • Pipe walls, king piles
