Blade-Segment PDC Core Bit for Geological & Mining Coring
Blade-segment PDC core drill bit with open flushing channels for geological and mining coring. Granite and other abrasive hard-rock applications require formation-specific confirmation.
Segmented PDC Crown for Controlled Coring and Open Flushing
This blade-segment PDC core bit uses separated cutting sections around an open core passage. The segmented crown provides flushing channels and distributes cutting contact for geological and mining coring. Hard-rock and granite applications require formation-specific cutter selection and field confirmation.
Segmented Cutting Crown
Separated blade sections provide defined cutting contact and open channels for fluid and cuttings.
Core Recovery Geometry
The open center supports sample recovery when matched to the correct core barrel.
Hard-Rock Review Required
Granite and quartz-rich rock can be highly abrasive; PDC grade, layout and operating parameters must be confirmed before use.

Selection and Operating Guidance
Recommended when
- Segmented cutting contact and open flushing channels are required.
- A core sample is needed for geological or mining assessment.
- Formation data is available for cutter selection.
Confirm before ordering
- Rock type, compressive strength, abrasiveness and fracture condition
- Outer diameter, core diameter, barrel and thread
- Rig speed, feed, flushing method and expected run length
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.
