Mitutoyo Inside Micrometer – 25–50 mm Range, 0.01 mm Resolution

This Mitutoyo Inside Micrometer (25–50 mm) is a precision Japanese‑made measuring instrument designed for accurate internal diameter measurement in machining, fabrication, toolmaking, and inspection environments. With a 25–50 mm range and 0.01 mm resolution, it provides fine control and reliable accuracy for bores, recesses, sleeves, and internal features where dependable comparative measurement is required.

The tool shows light fretting on the sliding shanks, a common cosmetic effect from moisture exposure during storage. This fretting does not impact the micrometer’s geometry, contact faces, calibration, or measurement performance.

Mitutoyo’s inside micrometers are known for stable mechanics, crisp graduations, and long‑term workshop durability.
