Mitutoyo - Holtest Bore Micrometer - 368 Series

  • These Holtests are versatile, self-centering three-point internal micrometers for the accurate and efficient direct-measurement of internal diameters.
  • Three anvils, evenly spaced at 120° apart, contact the internal wall surfaces and find true alignment with the axis of the bore for accurate ID measurement.


  • TiN-coated measuring contact points (over 6mm / .275” range models) provide
    excellent durability and impact resistance and allow the instrument to measure to
    the bottom of a blind hole (up to 100mm / 4”models).
  • Highly durable because of carbide-tipped contact points(anvils up to 12mm / .5”models).
  • Measure deep holes using an extension rod (optional) which is available on models over
    6mm (.275") measuring range.
  • With Ratchet Stop for constant force.
  • Setting rings for zero point adjustment are optional.
    • Supplied in fitted plastic case up to 100mm / 4”. Over 100mm / 4” supplied in wooden case.
