Holtests capable of measuring inner dimensions from 2mm to 200 (metric set) and.08′′ to 8′′ are included in the Mitutoyo Holtest mechanical three-point internal micrometre full sets (inch set). Each size is covered by the Mitutoyo mechanical Holtest internal micrometre set, which contains complete gauges (micrometre head units and measurement heads). The axis hole is true aligned with three hardened steel anvils evenly separated at 120° for accurate, repeatable measurements. The ratchet stop mechanism of the holtest ensures a constant measuring force on the hardened-steel spindle, ensuring accurate and consistent measurements.
