Flat-Top Coreless PDC Drill Bit for Water Well & Grouting
Flat-top coreless PDC drill bit with a broad cutting face for stable water-well, grouting and geological drilling in formation-matched conditions.
Flat-Top Coreless Cutting for Stable Hole-Bottom Contact
This flat-top PDC bit uses a broad, level cutting face for stable coreless drilling and straightforward hole-bottom cleaning. It is suited to geological, water-well and grouting work in formations that match the selected PDC cutter grade and flushing design.
Broad Flat Cutting Face
A level crown provides stable contact and a simple cutting path across the hole bottom.
Coreless Bore Production
The solid face removes the full bore rather than preserving a core sample.
Configurable Flushing
Waterways, cutter arrangement, diameter and thread can be matched to the rig and formation.

Selection and Operating Guidance
Recommended when
- A full-diameter coreless bore is required.
- Stable flat hole-bottom contact is preferred.
- The project involves water wells, grouting or geological drilling.
Confirm before ordering
- Formation hardness, abrasiveness, fracture condition and clay content
- Diameter, target depth, thread and drill string
- Rig torque, rotary speed, weight-on-bit and flushing capacity
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.
