3-Wing Concave PDC Drill Bit for Water Well & Geothermal Drilling
Three-wing concave coreless PDC drill bit for fast, self-cleaning drilling in soft to medium-hard formations used in water wells, geothermal exploration, grouting and coal-mine projects.
Aggressive Three-Wing Cutting with Concave Tracking Stability
This three-wing concave coreless PDC bit is designed for fast penetration in soft to medium-hard sedimentary formations. The concave center helps the bit track, while the open three-wing layout supports self-cleaning and efficient cuttings removal.
Concave Tracking Profile
The recessed center helps stabilize the cutting face and guide the bit during coreless drilling.
Open Three-Wing Geometry
Wide spaces between wings improve flushing and reduce packing in clay-rich formations.
Multi-Project Configuration
Suitable configurations can be built for water wells, geothermal holes, grouting holes and coal-mine work.

Selection and Operating Guidance
Recommended when
- Fast coreless penetration is required in soft to medium formations.
- Clay or mud makes self-cleaning geometry important.
- The project involves a water well, geothermal, grouting or coal-mine bore.
Confirm before ordering
- Formation hardness, abrasiveness and fracture condition
- Diameter, target depth and required thread
- 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.
