Mitutoyo 5-25mm Inside Digit Micrometer

Description

Product Overview

This Mitutoyo Caliper-Type Inside Digit Micrometer is designed for highly accurate measurements of internal diameters, bore sizes, and slot widths in the 5mm to 25mm range.

• Mechanical Digit Counter: The standout feature of this tool is its built-in mechanical counter. It provides a direct, easy-to-read numeric display of the measurement without the need for batteries or fragile electronics. This makes it incredibly reliable in shop environments where electronic calipers might fail.
• Caliper-Type Jaws: Unlike tubular micrometers, this tool uses caliper-style jaws. The measuring faces are specifically contoured to make perfect contact with the inside curved walls of a bore, ensuring accurate ID measurements.
• Carbide Tipped: The measuring faces are finished with premium solid carbide. Because inside micrometers undergo a lot of sliding friction as they are “swept” across a bore, the carbide ensures the jaws will not wear down and lose calibration over time.
• Ratchet Stop: Equipped with a constant-force ratchet mechanism on the thimble. This ensures that every measurement has the exact same pressure applied, guaranteeing repeatable results regardless of the operator’s touch.

Condition

Used (Mismatched Case / Accurate).

This inside digit micrometer is in used condition, well-maintained, and measures accurately. The digit counter rolls over smoothly and easily.

• Important Note on Packaging: The tool itself is stamped and measures 5-25mm. However, it comes housed in a Mitutoyo case (with accompanying papers) for a model 245-185 (which is a 5-30mm model).
• Included: Despite the mismatched case, it still safely protects the tool and includes an adjustment spanner for zeroing.

Brand Information

Mitutoyo Corporation (Japan) is the undisputed global benchmark for dimensional metrology. Their mechanical digit tools are highly sought after by traditional machinists who want the quick-reading convenience of a modern tool combined with the robust reliability of pure Japanese mechanics.
