Solitary ring bit system is designed for drilling end-bearing piles through overburden into bedrock. The system can drill straight and inclined piles through boulders and rock layers and it easily manages situations where the bedrock itself is inclined. The heavy duty ring bit is not attached to casing shoe, which makes it the most economical option of the ring bit alternatives.
The system is available for casings from 114 to 1 524 mm and for all major shank designs. It uses Spiral Flush technology, offering class-leading safety in overburden drilling. The solitary double-shoulder pilot is not compatible with the small integrated single-shoulder ring bits.
