It covers a measurement range of 0.09 to 1 inch with an accuracy of 0.0001 inch, making it suitable for precision tool inspection in machine shops and toolroom environments. The V-shaped anvil seats against two flutes while the spindle contacts the third, giving a true diameter reading across an odd number of flutes. Both the anvil and spindle contact faces are carbide-tipped for long-term wear resistance. A ratchet stop thimble ensures consistent measuring force on every reading.\u003c\/p\u003e\u003cp\u003eThis micrometer is used in machining and metalworking applications where three-flute cutting tool geometry requires a dedicated V anvil design rather than a standard flat-anvil micrometer. Typical users include tool and die makers, CNC machinists, and toolroom inspectors who need repeatable diameter verification on three-flute end mills, drills, or similar rotary cutting tools. The instrument ships with a protective case, a short-form certificate of calibration, and reference standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eV anvil geometry seats two flutes for accurate three-flute tool diameter measurement\u003c\/li\u003e\n\u003cli\u003eMeasurement range: 0.09 to 1 inch\u003c\/li\u003e\n\u003cli\u003eAccuracy: 0.0001 inch\u003c\/li\u003e\n\u003cli\u003eCarbide anvil and spindle contact faces resist wear during repeated use\u003c\/li\u003e\n\u003cli\u003eRatchet stop thimble delivers consistent measuring force for repeatable readings\u003c\/li\u003e\n\u003cli\u003eIncludes protective case, short-form calibration certificate, and standards\u003c\/li\u003e\n\u003cli\u003eRotating spindle design for standard micrometer operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for measuring the diameter of three-flute rotary cutting tools including end mills, taps, and reamers where a standard flat-anvil micrometer cannot produce an accurate cross-diameter reading.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis instrument is used by machinists and toolroom technicians and requires no installation. Before use, verify the zero setting against the included standards and confirm the calibration certificate is current for your quality system requirements. Store the micrometer in its case when not in use to protect the carbide contact faces and maintain calibration integrity. Handle with clean, dry hands or cotton gloves to prevent corrosion on precision surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.09 to 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes Measured\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Mechanical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnvil Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Material\u003c\/strong\u003e: Carbide\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\u003eFinish\u003c\/strong\u003e: Painted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7.49 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.23 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Case, Short-Form Certificate of Calibration, Standards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: CMS160809115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51692857557298,"sku":"CMS160809115","price":398.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35eeb3072e7b33f2f5cdf2aedd01b7de.jpg?v=1788304130","url":"https:\/\/voomisupply.com\/products\/spi-cms160809115-v-anvil-micrometer-0-09-1-in-3-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
