Half-Blade Scraper PDC Core Bit for Water Well & Geological Coring
Segmented half-blade scraper PDC core bit with open waterways for cooling, cuttings evacuation and sample recovery in water-well and geological coring.
Segmented Scraper Crown for Better Flushing and Core Entry
This half-blade scraper PDC core bit uses separated cutting segments around an open core passage. Compared with a continuous full-piece crown, the segmented layout provides more open flow space for cooling and cuttings evacuation.
More Open Flushing Space
Separated cutting segments leave larger waterways around the crown to move cuttings and cool the face.
Controlled Core Entry
The open center supports core entry when the bit is matched to the required core barrel.
Project-Matched Geometry
Outer diameter, core opening, segment arrangement and thread can be configured after technical review.

Selection and Operating Guidance
Recommended when
- Cuttings evacuation around the crown is a priority.
- A core sample and open central passage are required.
- The core system dimensions are available for matching.
Confirm before ordering
- Outer diameter, inner core diameter and crown geometry
- Core tube / barrel and connection dimensions
- Formation condition, flushing medium and rig parameters
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.
