SERIES 368 - Holtest Three-Point/Two-Point Bore Micrometers

Non-digital 2-point & 3-point Mitutoyo bore micrometers, suitable for measuring the diameter of small holes. Hardened steel contact faces. Ratchet stop guarantees repeatable measurement.

  • Ratchet Stop ensures constant-force, repeatable measurement.
  • Optional setting rings are available for setting the instrument accurately before measurement.
  • Three-point bore micrometer with a measuring range of 6 mm or larger allows stable measurement through automatic centering.
  • Can measure deep holes using an Extension rod (optional) which is available on models over 6 mm (.275") measuring range.
  • Titanium-coated measuring pins on the three-point type (over 6 mm range models) provide excellent durability and impact resistance and allow the instrument to measure right to the bottom of a blind hole.
