4-Wing Arc-Edge PDC Drill Bit for Deep Well & Mining
Four-wing arc-edge coreless PDC drill bit for stable deep water-well, geothermal, mining and ventilation-hole drilling after formation and rig review.
Four-Wing Arc-Edge Stability for Deep Coreless Boreholes
This four-wing arc-edge PDC bit combines a broad, balanced cutting structure with curved edge contact for stable coreless drilling. It can be configured for deep water-well, geothermal, mining, blasting and ventilation-hole projects after formation and rig review.
Balanced Four-Wing Contact
Four wings distribute cutting load and support stable large-diameter coreless drilling.
Arc-Edge Cutting Profile
Curved edge contact helps maintain a consistent cutting path and hole shape.
Deep-Bore Configuration
Diameter, cutter layout, gauge protection, waterways and thread are selected for bore depth and rig capacity.

Technical Specifications
| Product type | Four-wing arc-edge coreless PDC drill bit |
|---|---|
| Cutting structure | Balanced four-wing fixed-cutter layout with arc-edge profile and flushing waterways |
| Body material | Alloy-steel / matrix-style body with PDC cutters, depending on confirmed build |
| Primary applications | Deep water wells, geothermal holes, mining/blasting holes and methane/ventilation bores |
| Recommended formations | Soft to medium-hard formations; harder or abrasive rock requires cutter and body review |
| Important safety note | Methane / ventilation-hole work must follow site gas-control, ventilation and drilling safety procedures |
| Available sizes | Current selectable sizes are shown above; large diameter, thread and gauge protection require engineering confirmation |
| Customization | Diameter, connection, cutter grade/layout, arc profile, waterways, gauge protection, hardfacing and packaging |
Selection and Operating Guidance
Recommended when
- A stable large-diameter coreless bore is required.
- The project involves deep wells, geothermal, mining, blasting or ventilation holes.
- Rig capacity and formation data are available for configuration.
Confirm before ordering
- Formation hardness, abrasiveness, fracture condition and gas-control requirements
- Diameter, depth, thread, drill string and rig torque
- Rotary speed, weight-on-bit, flushing medium/flow 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.
