    Frequently asked questions

    For broken or loose formations, we recommend a stepped or face-discharge crown with wider waterways. When matched with an NQ3, HQ3 or PQ3 triple-tube system, core recovery and sample protection are improved.

    With the correct bit, core barrel and drilling parameters, wireline core drilling can achieve 95%+ core recovery in suitable formations. Actual recovery depends on rock condition and operator settings.

    Yes. Our bits are designed for common Q-series wireline core barrel systems, including BQ, NQ, HQ, PQ and PHD. Please confirm the bit size and barrel model before ordering.

    We manufacture in-house across dedicated workshops, with full control over raw material selection, machining, heat treatment, and assembly. Every unit is inspected before shipping. You get factory-direct pricing without compromising on field reliability.
