Flat-Tooth Diamond Core Bit for Hard-Rock Geological Coring
Flat-tooth diamond core drill bit for hard-rock geological coring and sample recovery. Correct bond/grit selection, controlled feed and continuous cooling are essential for performance and bit life.
Diamond Cutting Crown for Hard-Rock Core Recovery
This flat-tooth diamond core bit is intended for geological coring and sample recovery in harder, abrasive formations. The diamond cutting crown requires controlled feed, suitable rotational speed and continuous water or drilling-fluid cooling to manage heat and protect the cutting surface.
Hard-Rock Cutting Surface
Diamond cutting elements provide the wear resistance needed for harder and abrasive formations.
Core Sample Recovery
The open center is designed to produce a cylindrical core when matched to the correct core barrel.
Cooling Is Essential
Continuous water or drilling-fluid circulation helps control heat, clear cuttings and extend crown life.

Selection and Operating Guidance
Recommended when
- Hard or abrasive formations require diamond rather than conventional PDC cutting structures.
- Core integrity is important for geological or mineral assessment.
- The rig can maintain controlled speed, feed and continuous cooling.
Confirm before ordering
- Rock type, hardness, abrasiveness and fracture condition
- Core-barrel standard, outer/inner diameter and connection
- Cooling/flushing capacity, rig speed, feed 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.
