With the Mitutoyo 103-138 outside micrometer, you achieve reliable and precise external measurements on every workpiece. Designed for machining on lathes and quality inspection in the workshop, it covers a measuring range of 25 to 50 mm with a clear 0.01 mm graduation for accurate readings. The integrated ratchet stop ensures a constant and repeatable measuring force, eliminating errors caused by uneven hand pressure. Thanks to the durable carbide-tipped measuring faces, the tool resists wear to maintain long-term accuracy during demanding jobs. With the included setting standard, you can verify and adjust your micrometer quickly for consistent results.
