Calibrated micrometer measures outside diameters from 0 to 1 inch (0 to 25 mm) with a resolution of 0.00005 inch (0.001 mm) and an accuracy of ±0.00005 inch, designed for precise measurements in harsh workshop conditions. LCD display shows measurements in both inches and metric units for easy reading and rapid unit conversion. Plastic components are oil resistant and the measuring faces are carbide tipped for durability in oily or abrasive environments, helping maintain long service life. Ratchet stop provides uniform pressure to ensure precise, repeatable measurements and reduce userinduced variation. 0 to 1 inch range makes it suitable for small to midsize cylindrical parts commonly found in machining, assembly, and maintenance workflows. Built for reliability in demanding environments where oil, coolant, and dust are present, while delivering stable performance and consistent readings. Use scenarios: In a lathe or milling operation, verify the outside diameter of turned shafts and spacers to ensure they meet specified tolerances during setup or inprocess checks. During maintenance or inspection, measure the OD of bearings, pins, and bushings after cleaning or lubrication to confirm fit and replacement needs. In quality control, perform quick OD checks on cylindrical components arriving from production to validate conformance before assembly.
