Key features

Retractable wing design allows drill bit to pass through casing, enabling simultaneous drilling and casing advancement in one pass.

Eliminate borehole collapse in loose overburden; eccentric system advances casing instantly, preventing costly re-drilling.

Field data shows 40% faster casing advancement in gravel and boulders than conventional concentric systems.

Engineered for slope stabilization, micro piling, and challenging ground conditions.
