Typical Applications
The bit features high sampling recovery, enabling accurate geological analysis, and therefore widely used in geological exploration.
In addition, thanks to the central discharge design, the risk of borehole wall collapse is significantly reduced, making RC drill bits extensively applied in deep-hole drilling operations such as water wells, oil and gas, and coalbed methane projects.
