Mitutoyo 368-881 Holtest Inside Micrometer, type II, 11 to 12"

Description

The Mitutoyo 368-881 Holtest Inside Micrometer, type II, 11 to 12" is a three-point internal micrometer designed for measuring the inside dimensions of bores. This Type II model is a more economical option in the Mitutoyo Holtest line, using hardened alloy steel anvils instead of titanium-coated carbide.

Key features

• Three-point contact: Three anvils, spaced at 120°, contact the inside walls of the bore. This self-centering design allows for stable and automatic alignment with the bore's axis for accurate measurements.
• Constant measuring force: A built-in ratchet stop ensures that a constant, uniform pressure is applied for every measurement. This helps minimize inconsistencies caused by differences in operator skill.
• Blind-hole measurement: The design allows for measurements to be taken closer to the bottom of blind holes compared to other types of internal micrometers.
• Laser-etched scale: The scale on the thimble and sleeve features laser-etched markings for high contrast and easy readability under various lighting conditions.
• Hardened alloy steel anvils: This feature makes the Type II a more economical choice while still offering durability for general-purpose use.
• Extension rod capable: For measuring deep holes, an optional extension rod can be attached to increase the measuring depth.
• Fitted wooden case: The micrometer is supplied in a wooden case to provide protection and proper storage.
