Mitutoyo 368-778 Holtest Inside Micrometer, type II, 200 to 225 mm

Description

The Mitutoyo 368-778 Holtest Inside Micrometer is a mechanical, three-point internal micrometer designed for accurately measuring inside diameters in the range of 200 mm to 225 mm. It is a Type II model, which features hardened tool-steel anvils instead of the more expensive titanium-coated carbide anvils found on other Holtest models.

Key features

• Self-centering design: The micrometer uses a three-point measuring method with anvils spaced 120° apart for stable, self-centering measurements of bores.
• Repeatable measurements: A built-in ratchet stop mechanism provides a constant measuring force, which ensures accurate and repeatable results.
• Ability to measure blind holes: The design allows for measurements to be taken closer to the bottom of blind bores.
• Laser-etched scale: The scale on the thimble and sleeve is laser-etched for improved readability in various conditions.
• Optional extension rod: For measuring deep holes, an optional extension rod can be attached.
• Wooden case: The micrometer comes supplied in a wooden case.
• Optional setting rings: Setting rings for zero point adjustment must be purchased separately.
