Mitutoyo Three/Two-Point Internal Holtest Micrometer, Series 368, 8" - 9" - 368-278


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.


Features:

  • TiN-coated measuring contact points(over 6mm/.275" range models) provide excellent durability and impact resistance and allow the instrument to measure right to the bottom of a blind hole.
  • Highly durable because of carbide-tipped contact points (anvils)
  • Measurement can be taken closer to the bottom of the blind bore
  • Can 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
