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.

Fast Quote Checklist

Send diameter, thread/connection, formation description, target depth, rig model, flushing method and quantity. Photos or geological reports improve configuration accuracy.
