Double-Tube TSP Core Bit for Hard-Rock Deep Sampling

Double-tube TSP core drill bit for hard-rock and deep geological sampling, combining thermally stable cutters with a matched sample-protection system.
Size: BQ / 2 3/8"

TSP Cutting with Double-Tube Protection for Deep Core Sampling

This TSP core bit is intended for hard-rock and deep sampling systems where thermally stable polycrystalline cutters and a double-tube core barrel help protect sample quality. Final performance depends on rock abrasiveness, cutter geometry, core-barrel compatibility and controlled operating parameters.

Thermally Stable Cutters

TSP cutting elements retain useful properties at higher cutting temperatures than conventional PDC in suitable hard-rock applications.

Double-Tube Sample Protection

A matched double-tube barrel helps isolate and protect the core during retrieval.

Deep-Sampling Configuration

Cutter layout, crown geometry, barrel standard and flushing must be configured for depth and formation.

Selection and Operating Guidance

Recommended when

  • Hard-rock core sampling requires heat-resistant cutting elements.
  • Core recovery and sample protection are priorities.
  • A compatible double-tube core barrel is available.

Confirm before ordering

  • Rock hardness, abrasiveness, fracture condition and target depth
  • Double-tube barrel standard, core diameter and connection
  • Rig speed, feed, flushing pressure/flow and expected run length

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