The Mitutoyo Holtest (Type II) mechanical three-point internal micrometer utilizes three self-centering anvils constructed of alloyed steel for accurate and efficient measurements of inside dimensions of bores. The Mitutoyo mechanical Holtest internal micrometer features three alloy steel anvils evenly spaced at 120° for true alignment of the axis bore for accurate, easily repeatable measurements. A hardened steel spindle with a carbide ball and cone with a carbide pin ensure accuracy and durability when extending and retracting the anvils. The holtest's ratchet stop mechanism provides a constant measuring force on the hardened-steel spindle to ensure accurate, even measurements.
