Mitutoyo 368-998 Holtest Micrometer Set, type II, 4 to 8"

Description

The Mitutoyo 368-998 Holtest Micrometer Set, type II, 4 to 8" is a three-point internal micrometer set designed for accurate and efficient measurement of bore diameters in a range of 4 to 8 inches. This mechanical, non-digital set utilizes alloyed-steel contact points for durability, which makes it a more economically priced alternative to the titanium-coated Holtest models. The set provides the same accuracy as the titanium-coated models.

Key features

• Accurate measurements: The three alloyed-steel contact points are self-centering and spaced 120° apart, ensuring true alignment with the bore's axis for accurate measurements.
• Repeatable results: A built-in ratchet stop ensures a constant, even measuring force for consistent and repeatable results.
• Blind hole measurements: The contact point geometry is designed to allow for measurement closer to the bottom of blind bore holes.
• Deep hole measurements: An extension rod is included in the set for measuring bores at greater depths.
• Laser-etched scale: The scale on the thimble and sleeve is laser-etched to improve readability in various conditions.
