Integrated ring bit systems, divided into small and large designs, are 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 integrated into casing shoe, which makes it safe to drill in loose ground and over water. The large size allows for double-shoulder design.
The large integrated system is available from 323 to 1 524 mm casings and for all major shank designs. It uses Spiral Flush technology, offering class-leading safety in overburden drilling.
