The Mitutoyo Holtest mechanical three-point internal micrometer utilizes three self-centering anvils with precision contact points for accurate and efficient measurements of inside dimensions of bores. The Mitutoyo mechanical Holtest internal micrometer features three hardened-steel anvils evenly spaced at 120° for true alignment of the axis bore for accurate, easily repeatable measurements. Contact points are coated with Titanium Nitride (TiN) for added durability and precision. The holtest's ratchet stop mechanism provides a constant measuring force on the hardened-steel spindle to ensure accurate, even measurements.
