Key features

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

Eliminate hole collapse in unstable slopes; concentric system ensures instant casing support in loose soils.

Field data shows 30% faster casing advancement in weathered rock and gravel than conventional systems.

Engineered for slope stabilization, landslide control, retaining wall anchors, and steep terrain projects.

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

Product Q&A

Q:How does the concentric block system work?

The blocks expand during drilling to advance the casing, and retract when pulling back, allowing the bit to pass through the casing.

Q:What is the advantage of concentric over eccentric systems for slope work?

Concentric systems provide better borehole straightness and are easier to retrieve in fractured ground, making them ideal for slope anchors.

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

It performs best in weathered rock, gravel, overburden, loose soils, and fractured rock formations.

Q:Can this bit be used with different hammer types?

Yes, it is compatible with DHD, SD, and QL series hammers. Please specify your hammer type when ordering.
