Mitutoyo Holtest, Series 368 (three point internal micrometer)

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.
