4-Wing Spiral PDC Drill Bit for Water Well & Coal Mining

Four-wing spiral coreless PDC drill bit for stable water-well, geological and coal-mine drilling with efficient cuttings flow.
Size: 113# / 4 1/2"

Four-Wing Spiral Coreless Bit for Water-Well and Coal-Mine Drilling

This four-wing spiral PDC bit is configured for coreless water-well, geological and coal-mine drilling where stable cutting contact and continuous cuttings flow are required. The spiral wing and waterway layout helps move debris away from the face during longer bore intervals.

Stable Four-Wing Cutting

Four wings distribute load and support smoother coreless drilling.

Spiral Debris Flow

Helical wing and waterway geometry helps move cuttings away from the bottom.

Underground and Well Configuration

Connection, gauge protection, cutters and flushing are selected for water-well or coal-mine rig conditions.

Selection and Operating Guidance

Recommended when

  • A stable coreless bore is required in water-well or coal-mine work.
  • Continuous cuttings flow is important during longer drilling intervals.
  • No cylindrical core sample is required.

Confirm before ordering

  • Formation hardness, abrasiveness, fracture condition and coal-mine safety requirements
  • Diameter, depth, connection, drill string and rig torque
  • Speed, weight-on-bit, flushing flow and quantity

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.
