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.
- Available in Metric and Inch models
- Optional extension rod allows for measuring deep holes
- Optional setting rings for zero point adjustment are available
- Design allows for measurements closer to the bottom of blind bore holes
- Scale on thimble and sleeve is laser etched for easier reading in all conditions
- Holtests up to 100mm / 4″ diameter measurements supplied in a fitted plastic case
- Holtests over 100mm / 4″ diameter measurements supplied in a wooden case
