Mitutoyo 368-867 Holtest Inside Micrometer, type II, 1 to 1.2"

Description

The Mitutoyo 368-867 Holtest Inside Micrometer, type II, 1 to 1.2" is a mechanical, three-point internal micrometer used for accurately measuring the inside diameter of bores. It features a self-centering mechanism and hardened steel contact points.

Key features

• Self-centering: The three anvils are evenly spaced at 120°, which ensures accurate alignment with the bore's axis for precise and repeatable measurements.
• Constant force: A built-in ratchet stop mechanism helps ensure that a consistent measuring force is applied, which improves the accuracy and repeatability of each measurement.
• Blind bore measurement: The design of the micrometer allows for measurements to be taken closer to the bottom of blind (non-through) holes.
• Durability and cost: The Type II Holtest uses hardened steel anvils instead of the more expensive titanium-coated carbide ones, providing an economical but durable alternative with the same accuracy as the titanium-coated models.
• Deep hole measurement: An optional extension rod can be attached to measure deep bores.
• Zero-point adjustment: Optional setting rings are available for precise zero-point adjustment before beginning measurements.
• Easy-to-read scale: The scales on the thimble and sleeve are laser-etched to improve readability.
