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.
Unique retraction mechanism ensures 99% recovery rate, reducing lost tool costs and drilling downtime.
