Key features

Drill and case simultaneously with retractable block design, advancing casing flush with the borehole wall in one pass.

Eliminate hole collapse in shallow gas formations; concentric system ensures instant casing support in unconsolidated zones.

Field data shows 30% faster casing advancement in gravel and boulder formations than conventional systems.

Engineered for shallow gas exploration, coalbed methane, and unconsolidated formation drilling.

Reinforced tungsten carbide blocks provide superior wear resistance, extending service life in abrasive ground.

Product Q&A

Q:How does the wing system differ from block system in tunneling?

Wing system provides larger contact area and better load distribution, making it more suitable for tunneling support applications.

Q:What is the advantage of concentric wing design for tunnel support?

It provides better borehole straightness and smoother casing advancement in fractured rock, essential for pipe roofing and spiling.

Q:What formations is this wing bit best suited for?

It performs best in fractured rock, hard rock, fault zones, overburden, and tunnel face conditions.
