Integrated M-Wall ring bit system is used to drill straight interlocked casings through boulders and rock layers even into inclined bedrock. M-Wall is a perfect solution to replace sheet piles and slurry walls in rocky ground conditions.
The integrated design means that the casing shoe and the ring bit are permanently connected together. This makes drilling over water safe as there is no risk of accidentally dropping the ring bit into water.
The system is available from 219 to 1 220 mm casings and for all major shank designs. It uses Spiral Flush technology, offering class-leading safety in overburden drilling.
