3-Wing Coreless Scraper Drill Bit for Soil & Mudstone
Open three-wing coreless scraper drill bit for fast drilling and cuttings removal in soil, clay, mudstone and other soft formations.
Open Three-Wing Scraper Geometry for Fast Soft-Formation Drilling
This three-wing coreless scraper bit uses a wide, open cutting layout for rapid penetration and cuttings evacuation in soil, clay, mudstone and other soft formations. It removes the full bore and is not intended to preserve a core sample.
Open Three-Wing Face
Wide spaces between scraper wings provide clear paths for cuttings and flushing.
Fast Soft-Formation Penetration
The aggressive scraper profile is suited to soil, clay, mudstone and comparable soft layers.
Simple Project Matching
Diameter, connection, blade/cutter material and flushing layout can be selected for the rig.

Selection and Operating Guidance
Recommended when
- Fast penetration is needed in soil, clay or mudstone.
- A coreless bore is required and no sample core must be preserved.
- Open geometry is needed to reduce packing.
Confirm before ordering
- Formation type, hardness, abrasiveness and clay content
- Diameter, thread, target depth and drill string
- 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.
