It delivers a maximum measurement range of 3 inches with a graduation of 0.0001 inches and an accuracy of 0.0001 inches, making it a reliable tool for work that demands tight tolerances. The micrometer features a ratchet stop thimble for consistent measuring force and a rotating spindle for smooth, controlled advancement. Solid carbide measuring faces resist wear over extended use. This instrument is used by machinists, tool and die makers, quality control technicians, and precision tradespeople who require repeatable, high-accuracy linear measurements in shop or field environments.\u003c\/p\u003e\n\u003cp\u003eThe T444.1XRL-3 is suited for external measurement of shafts, pins, stock material, and machined components in both production and inspection settings. The flat anvil type accommodates a wide range of workpiece geometries. It ships with a protective case and a wrench, making it ready for immediate deployment at a workbench or inspection station. The satin chrome finish reduces glare and corrosion during regular shop use. This micrometer is appropriate for any trade or industrial environment where dimensional accuracy to 0.0001 inches is required on workpieces up to 3 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch maximum measurement range with 0.0001-inch graduation for high-resolution readings\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.0001 inches for tight-tolerance inspection work\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble provides consistent, repeatable measuring pressure\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring faces for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eRing-style lock nut secures the spindle position during reading or transfer\u003c\/li\u003e\n  \u003cli\u003eSatin chrome coating reduces glare and protects against corrosion\u003c\/li\u003e\n  \u003cli\u003eIncludes protective case and wrench for storage and adjustment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard mechanical outside micrometer for external dimensional measurement of cylindrical and flat workpieces up to 3 inches in diameter or thickness.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCalibration and use of precision measuring instruments should be performed by qualified machinists or metrology technicians familiar with proper zeroing and anvil-cleaning procedures. Before use, clean both measuring faces with a lint-free cloth and verify the zero setting against a calibrated standard. Do not overtighten the spindle or force the thimble, as this can damage the measuring faces or affect calibration. Store the micrometer in its case when not in use to protect the carbide faces and maintain accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Nut Type\u003c\/strong\u003e: Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Case, Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompliance\u003c\/strong\u003e: California Proposition 65\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T444.1XRL-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542378742066,"sku":"T444.1XRL-3","price":249.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66d5d128bfc1d545aaaceac270d07bb7.jpg?v=1785899074","url":"https:\/\/voomisupply.com\/products\/starrett-t444-1xrl-3-outside-micrometer-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
