Full-Piece Scraper PDC Core Bit for Water Well & Geological Coring
Full-piece scraper-style PDC core bit with an open central passage for water-well coring, geological exploration and formation sampling. Core opening, thread and cutting structure can be matched to the project.
Full-Face Scraper Cutting with a Clear Core Passage
This full-piece scraper-style PDC core bit is built for efficient coring and sample recovery in water-well and geological work. The continuous cutting face supports even contact, while the open center preserves the core path.
Continuous Scraper Face
The full-piece cutting structure distributes contact around the crown for consistent coring.
Open Core Passage
The central opening supports core entry and sample recovery when matched to the correct core tube.
Matched to Your Core System
Diameter, inner opening, connection and waterway must be confirmed against the core barrel and formation.

Selection and Operating Guidance
Recommended when
- A core sample is required rather than a fully coreless bore.
- The formation is stable enough for scraper-style coring.
- The core barrel and connection dimensions can be supplied for matching.
Confirm before ordering
- Outer diameter and required core diameter
- Core tube / barrel dimensions and thread
- Formation hardness, abrasiveness, fracture condition and flushing method
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.
