4-Wing Spiral PDC Drill Bit for Deep Well & Geothermal Drilling
Four-wing spiral coreless PDC drill bit designed to improve cuttings removal and reduce packing in deep water-well, geothermal and mine drilling, especially in clay-rich or muddy formations.
Spiral Waterways for Cleaner Deep-Well Drilling
This four-wing spiral PDC bit combines a balanced coreless cutting layout with open spiral waterways. The design is intended to move clay-rich cuttings away from the face, reduce packing and maintain steady penetration in deep water-well and geothermal work.
Improved Cuttings Removal
Spiral waterways provide a clearer flow path where sticky clay and mud can otherwise pack around the bit.
Stable Four-Wing Layout
Balanced wings support consistent hole geometry and smoother torque response.
Configurable for the Rig
Diameter, connection, cutter layout, waterway and hardfacing can be confirmed for the project.

Selection and Operating Guidance
Recommended when
- Sticky or clay-rich formations tend to pack around conventional bit faces.
- A coreless bore and effective flushing are required.
- The project is a deep water well, geothermal well or mine-related bore.
Confirm before ordering
- Formation hardness, abrasiveness and clay content
- Hole diameter, depth and required connection
- Rig torque, rotary speed and flushing capacity
Performance depends on formation, rig parameters, flushing and operating practice. Final configuration should be confirmed by the technical team.
