Double-Rib PDC Core Bit for Exploration & Mining Coring
Double-rib PDC core drill bit with paired cutting support for stable, wear-distributed coring in geological exploration, mining and coal-mine projects.
Double-Rib Cutting Support for Stable, Durable Coring
This double-rib PDC core bit uses paired cutting support on each crown segment to improve stability and distribute wear during exploration and mining coring. The open center and separated segments maintain a clear path for the core and flushing flow.
Paired Cutting Support
Double-rib / paired cutter support spreads contact and can improve crown stability compared with a lighter single-rib layout.
Stable Sample Path
The central opening and balanced segments support controlled core entry and recovery.
Customizable Crown
Rib geometry, cutter arrangement, size, connection and waterways can be matched to the formation and core system.

Selection and Operating Guidance
Recommended when
- More crown support and wear distribution are required than a lighter ribbed design.
- A stable core sample is needed for exploration or mining assessment.
- The core-barrel and connection dimensions can be provided.
Confirm before ordering
- Formation hardness, abrasiveness and fracture condition
- Outer diameter, sample diameter, core barrel and thread
- Rig parameters, flushing method, target depth and quantity
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.
