To Achieve a Wide Variety of Core Sampling Successes

Among our models, especially the triple tube type tends to be used more frequently as it meets the most critical requirement (natural state).

It is structured with a triple tube system, consisting of an outer tube, inner tube, and sample tube (acrylic), and is used for sampling, although there are differences in geology.

We also have a variety of end parts available to accommodate continuous geology.

Sizes are 76φ, 86φ, 100φ, 116φ, all 1m long

NEW Outer Tube

Features: Hard-faced Diamond-Embedded Outer Tube

  • Ideal for maintaining and holding the outer diameter of the diamond bit tip.
  • Acts as a stabilizer by connecting to the outer pipe on both sides.
  • The hard part is located on the outside of the thread, also serving to protect the inner threads.
  • Finished with a thermal spraying bond of diamond particles to a special metal.
  • Reduces friction resistance with the borehole wall in high viscosity situations.
