Reinforced Rounded-Cutter PDC Core Bit for Coal & Exploration
Reinforced ribbed PDC core bit with thickened rounded cutting elements for stable, impact-tolerant coring in coal-mine, geological exploration and water-well sampling projects.
Reinforced Rounded Cutters for Impact-Tolerant Coring
This reinforced ribbed PDC core bit uses thickened rounded cutting elements on separated crown ribs. The rounded profile is intended to improve impact tolerance and maintain stable cutting contact in variable coal-mine and exploration formations.
Thickened Rounded Cutters
Rounded reinforced cutting elements provide a less aggressive contact profile for variable or locally fractured formations.
Ribbed Open Crown
Separated ribs leave open channels for flushing, cooling and cuttings evacuation.
Core-System Matching
Crown geometry, core opening, cutter layout and thread are configured around the actual sampling system.

Technical Specifications
| Product type | Reinforced rounded-cutter ribbed PDC core drill bit |
|---|---|
| Cutting structure | Separated crown ribs with thickened rounded / helmet-style PDC cutting elements |
| Body material | Alloy-steel body with reinforced PDC cutting elements |
| Primary applications | Coal-mine exploration, geological coring, water-well sampling and variable-formation drilling |
| Recommended formations | Soft to medium-hard and locally fractured formations where impact tolerance is more important than maximum aggressiveness |
| Not recommended without review | Very hard or highly abrasive formations requiring TSP or diamond-matrix designs |
| Available sizes | Current selectable outer diameters are shown above; inner core opening and crown geometry require confirmation |
| Customization | Outer/inner diameter, rib and cutter layout, connection, waterways, hardfacing, color and packaging |
Selection and Operating Guidance
Recommended when
- The formation varies or contains locally fractured intervals.
- Stable coring and cutter impact tolerance are priorities.
- A core sample is required in coal-mine or exploration work.
Confirm before ordering
- Formation variability, hardness and abrasiveness
- Core barrel, outer diameter, inner opening and thread
- Rig parameters, flushing medium and expected sample 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.
