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.

Why choose reverse circulation drill bits, and which hammers are they compatible with?

Due to the unique reverse circulation structure, RC drill bits provide unmatched advantages in geological sampling accuracy and borehole stability. Once an RC drill bit is selected, it must operate within a complete reverse circulation drilling system. RC drill bits are only compatible with dedicated RC hammers designed for reverse circulation applications.

How is the appropriate RC drill bit selected?

Selection is typically based on the following information:

  • Standard RC hammer model and required drill bit diameter
  • Drill bit drawings or physical samples for precise matching
  • Required drill bit diameter together with formation conditions and drilling depth, allowing proper matching of RC hammer and drill bit combinations
