Delivered in a complete set with box, key, and setting standard, it’s designed for reliable everyday use.
The Mitutoyo 103-145-10 is an analog outside micrometer featuring a 200–225 mm measuring range, ±4 µm maximum permissible error, and 0.6 µm flatness accuracy. Equipped with a ratchet stop for repeatability, spindle lock, and carbide-tipped, micro-lapped measuring faces, it provides precision in a rugged, easy-to-handle design. The spindle pitch of 0.5 mm ensures smooth operation, while its satin chrome finish prevents glare and improves visibility. Lightweight for its size at 1080 g, this micrometer is suitable for workshop and inspection room applications.
Choose the Mitutoyo 103-145-10 for its unbeatable balance of affordability and performance. It offers precision measuring capabilities without compromising durability, making it ideal for both entry-level users and seasoned professionals. Its proven economy design ensures you get trusted Mitutoyo accuracy at a cost-effective price point. With robust carbide-tipped measuring faces and reliable ratchet-stop functionality, this micrometer is built to deliver consistent results across demanding industrial environments.
The Mitutoyo 103-145-10 solves the challenge of achieving reliable, repeatable external measurements in the 200–225 mm range without the expense of high-end digital instruments. In environments where accuracy, cost control, and durability matter, this micrometer bridges the gap by offering precision at an economical price. It helps eliminate errors from inconsistent measuring force with its ratchet-stop mechanism and ensures long-term performance through wear-resistant carbide-tipped anvils—making it an essential tool for manufacturing, inspection, and quality assurance tasks.
During final turning or grinding, operators verify large shafts and rollers before release to assembly. The ratchet mechanism ensures consistent measuring force, reducing variation between shifts. Carbide‑tipped faces resist wear from coolant residue and micro‑chips, while the satin chrome scale stays readable under bright task lights. A quick lock on the spindle lets inspectors record values hands‑free, improving traceability and first‑pass yield.
Fabricators check outside diameters of heavy-gauge tubes after weld and cleanup to confirm fit with sleeves or bushings. The analog scale avoids battery dependency in hot, high‑vibration bays, and the included setting standard helps crews confirm zero at the start of each shift. The tool’s robust frame and micro‑lapped faces maintain accuracy despite thermal fluctuation, helping prevent rework from mismatched joints and out‑of‑round parts.
Assembly teams validate bearing seats and housings to ensure interference/clearance targets are met. Consistent force from the ratchet stop reduces operator‑to‑operator differences, tightening Cp/Cpk. The spindle lock enables repeat checks at reference points without losing position, useful for gauge studies or GR&R. Durable carbide faces minimize drift over long runs, while analog readability accelerates spot checks where fast, reliable decisions matter more than data logging.
QA labs use the micrometer as a stable analog reference to cross‑check digital instruments when diagnosing measurement disputes. The fine graduation supports comparative studies, while the setting standard streamlines quick verification before gauge issue. Its rugged build and predictable feel help isolate technique errors versus instrument errors. As a battery‑free backup, it keeps inspection moving during unexpected downtime, protecting schedules and preventing bottlenecks.
