Single-Rib PDC Core Bit for Water Well & Coal Exploration

Open single-rib PDC core drill bit for efficient flushing and formation sampling in water-well, coal-mine and geological exploration.
Size: 75# / 3"

Open Single-Rib PDC Crown for Efficient Core Sampling

This single-rib PDC core bit uses a lighter, open crown layout for efficient cutting and flushing in water-well, coal-mine and geological sampling. Compared with a double-rib crown, the single-rib structure provides more open flow but less cutting support and wear distribution.

Open Single-Rib Layout

A lighter crown leaves open channels for flushing and cuttings removal.

Efficient Formation Sampling

The central passage supports core entry for geological and coal-mine assessment.

Clear Selection Trade-Off

Choose single rib for openness and efficient cutting; choose double rib when greater support and wear distribution are needed.

Selection and Operating Guidance

Recommended when

  • Open flushing and efficient cutting are priorities.
  • A core sample is required in water-well, coal or geological work.
  • The formation suits a lighter PDC coring structure.

Confirm before ordering

  • Formation hardness, abrasiveness and fracture condition
  • Core diameter, outer diameter, barrel and connection
  • Rig speed, feed, flushing capacity and target depth

Performance depends on formation, rig parameters, flushing and operating practice. Final configuration should be confirmed by the technical team.
