Mitutoyo 368-870 Holtest Inside Micrometer, type II, 2 to 2.5"

Description

The Mitutoyo 368-870 Holtest Inside Micrometer, type II, 2 to 2.5" is a mechanical, three-point internal micrometer used for accurately measuring the inside diameter of bores. The type II model features hardened alloy steel anvils for a more economical option compared to other series that use titanium-coated carbide. The tool comes with a fitted plastic case and has a satin chrome finish to resist rust and reduce glare.

Key features

• Economical option: The use of alloy steel contact points instead of titanium-coated carbide makes the type II series more affordable, while still maintaining high accuracy.
• Easy readability: The scale on the thimble and sleeve is laser-etched for easier reading in different lighting conditions.
• Consistent measurement: A ratchet stop provides constant measuring force, which ensures consistent and repeatable results with minimal user variation.
• Ability to measure deep holes: For measuring deeper holes, an optional extension rod can be attached to the tool.
• Self-centering design: The three anvils are spaced at 120° for proper alignment and self-centering within the bore, providing accurate inside diameter measurements.
