Product Q&A

Q:How does the open closed mechanism work?

The wings open by rotation and hydraulic pressure when drilling, and close when pulled back, allowing casing to be run over the bit.

Q:Is this bit suitable for cased hole drilling?

Yes, it is specifically designed for casing while drilling applications in unconsolidated formations.

Q:What is the maximum opening diameter?

The bit expands to approximately 30% larger than the closed diameter, depending on the specific model.

Q:Can this bit be used in hard rock formations?

This design is optimized for soft to medium formations. For hard rock, please consider our concave or directional series.

Q:How do I maintain the hinge mechanism?

Regular inspection and proper lubrication of moving parts are recommended. Avoid excessive WOB during opening and closing.
