It features a spherical spindle and carbide ball anvil, both 6.5 mm in diameter, that make positive contact on rounded workpiece geometries where a flat anvil would give false readings. The measuring range runs from 0 to 1.00 inch with a resolution of 0.0001 inch, and a digital counter display provides fast, reliable readout. A ratchet thimble delivers consistent measuring pressure, and a positive lock nut holds the set position during transfer or recording. Calibration is included from the factory to ASME B89.1.13 standards. This tool weighs 0.85 pounds and packages at approximately 7 inches long, 3.4 inches wide, and 0.97 inches in height.\u003c\/p\u003e\n\u003cp\u003eThe CMS220519021 is suited for metrology, quality control, and precision inspection work in manufacturing, tooling, and machine shops. It is particularly useful when measuring the wall thickness of tubes, the radius of curved parts, or any application where standard flat-anvil micrometers cannot seat properly on the part surface. The electronic readout reduces transcription error during high-volume inspection runs. Licensed metrologists, machinists, and QC technicians are the primary users of this instrument.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide ball anvil and spherical spindle, each 6.5 mm in diameter, for accurate contact on curved surfaces\u003c\/li\u003e\n  \u003cli\u003eElectronic digital counter display with 0.0001 inch resolution\u003c\/li\u003e\n  \u003cli\u003eRatchet thimble ensures repeatable, consistent measuring force\u003c\/li\u003e\n  \u003cli\u003ePositive lock nut secures the spindle position during transfer measurement\u003c\/li\u003e\n  \u003cli\u003eRotating spindle design for fine adjustment and seating\u003c\/li\u003e\n  \u003cli\u003eFactory calibrated to ASME B89.1.13\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision measuring instrument for use in standard bench and in-process inspection applications requiring a 0 to 1.00 inch ball anvil micrometer with electronic readout.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument is handled and calibrated by metrologists or trained QC personnel. Store the micrometer in its case when not in use and keep it away from vibration, heat sources, and corrosive environments. Before use, verify the zero setting with the supplied standard and wipe the anvil and spindle faces clean with a lint-free cloth. Do not overtighten the lock nut, as this can damage the spindle thread and affect accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Range\u003c\/strong\u003e: 0 to 1.00 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0001 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.0001 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Electronic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: Ball (Carbide)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Diameter\u003c\/strong\u003e: 6.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Type\u003c\/strong\u003e: Spherical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Material\u003c\/strong\u003e: SUS420F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 6.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Nut Type\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B89.1.13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7 inches (L) x 3.4 inches (W) x 0.97 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111601\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CMS220519021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691694817586,"sku":"CMS220519021","price":319.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bbfad0172d1ae0a7d9ebbaf3dc4eea9_1b6b9cee-51f7-455a-9c1b-9da4543f71ac.jpg?v=1788288599","url":"https:\/\/voomisupply.com\/products\/spi-cms220519021-ball-anvil-micrometer-0-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
