The MITUTOYO Outside Micrometer 50–75mm (Series 103) is a high-precision measuring instrument designed for accurate external measurement of medium-sized components such as shafts, pipes, and machined parts.
With a measurement range of 50–75mm, this micrometer is an essential tool in any complete micrometer set, following the 0–25mm and 25–50mm ranges. It features a 0.01mm graduation, delivering precise and repeatable measurements required in machining, fabrication, and quality inspection.
The micrometer is equipped with a ratchet stop mechanism, ensuring consistent measuring force and minimizing operator error. Its carbide-tipped measuring faces provide excellent wear resistance, maintaining long-term accuracy even in heavy industrial use.
Built with a baked enamel-coated frame, the tool offers durability and resistance to environmental conditions. The satin chrome scale ensures clear, glare-free reading, while the spindle lock allows secure measurement holding.
