6-Tooth PDC Core Bit for Geological Survey & Water-Well Sampling
Six-tooth PDC core drill bit with balanced cutting contact and open flushing channels for geological survey, coal-mine exploration and water-well formation sampling.
Six-Tooth Cutting Balance for Efficient Core Sampling
This six-tooth PDC core bit distributes cutting contact around the crown to support steady penetration and core entry in geological survey, coal-mine and water-well sampling. The open channels between teeth provide paths for flushing and cuttings removal.
Six-Tooth Load Distribution
Six cutting points distribute contact around the crown for balanced coring.
Open Flushing Channels
Spaces between teeth help cool the cutters and move cuttings away from the core face.
Confirmed Speedmade Configuration
The Speedmade Alibaba range includes a 91 mm six-tooth model with 1304 PDC blades; other sizes require confirmation.

Selection and Operating Guidance
Recommended when
- Balanced multi-tooth contact is preferred for core sampling.
- The project requires geological, coal-mine or water-well formation samples.
- Open flushing between crown teeth is beneficial.
Confirm before ordering
- Formation type, abrasiveness and fracture condition
- Outer diameter, core diameter, thread and core-barrel dimensions
- Rig model, speed, feed, flushing method and target depth
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.
