6-Tooth Spherical PDC Core Bit for Exploration & Sampling

Six-tooth spherical PDC core drill bit with rounded cutting elements for stable, impact-tolerant coring in geological exploration, water-well and geothermal sampling.
Size: 75# / 3"

Rounded Six-Tooth Contact for Stable, Impact-Tolerant Coring

This six-tooth spherical PDC core bit combines a balanced crown with rounded cutting elements. Compared with sharper flat cutters, the rounded profile provides less aggressive contact and can improve stability and impact tolerance in variable formations.

Rounded Cutter Profile

Spherical / rounded cutting elements provide a stable contact profile for variable formations.

Balanced Six-Tooth Crown

Six cutting positions distribute contact around the core passage.

Impact-Tolerant Selection

Useful where local fractures or formation changes make a highly aggressive cutter less suitable.

Selection and Operating Guidance

Recommended when

  • Formation variability or local fractures require a less aggressive contact profile.
  • Balanced six-tooth coring and sample recovery are required.
  • The project involves exploration, water-well or geothermal sampling.

Confirm before ordering

  • Formation hardness, abrasiveness and fracture condition
  • Core diameter, outer diameter, barrel and connection
  • Rig speed, feed, flushing capacity and target depth

Performance depends on formation, rig parameters, flushing and operating practice. Final configuration should be confirmed by the technical team.
