Mitutoyo Holtests with TiN Anvil Coating

Features:

These Holtests are versatile, self-centering three-point internal micrometers for the accurate and efficient direct-measurement of internal diameters. Three anvils, evely 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 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
