Solitary ring-bit systems are designed for drilling end-bearing piles through boulders, rock layers, and even into inclined bed rock.
The heavy-duty ring-bit is not attached to the casing shoe, making it the most economical ring-bit solution.
- End-bearing piles, including micro piling
- Pilings with sacrificed casings, which have no large ID ring-bit requirements
- Slope stabilisation
- Pipe walls, king piles
