5-Wing Helical PDC Drill Bit for Marble & Stone Mining
Five-wing helical PDC drill bit designed for stable cutting-load distribution and efficient cuttings flow in marble, limestone and selected stone-mining applications.
Five-Wing Helical Control for Stone and Marble Drilling
This five-wing helical PDC drill bit is designed to distribute cutting load across a wider, more stable face while spiral flow paths move cuttings away from the hole bottom. It is intended for controlled drilling in marble, limestone and comparable stone formations after application review.
Five-Wing Load Distribution
More cutting wings distribute contact around the bore and support smoother drilling response.
Helical Cuttings Flow
Spiral channels help direct cuttings away from the cutting face and reduce recutting.
Stone-Project Configuration
Cutter grade, layout, connection and diameter should be selected for the specific marble or stone formation.

Selection and Operating Guidance
Recommended when
- Stable, controlled coreless drilling is required in marble or similar stone.
- A five-wing layout is preferred for load distribution and bore stability.
- Cuttings removal and reduced recutting are important.
Confirm before ordering
- Stone type, abrasiveness, fracture condition and required hole quality
- Diameter, depth, thread and drill-string details
- Rig torque, rotary speed, flushing method 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.
