It reads from 0.078 to 1 inch with a graduation of 0.0001 inch, making it suitable for high-precision inspection work. The V-shaped anvil cradles the tool while the carbide spindle contacts the opposing flute. A ratchet stop thimble ensures consistent measuring pressure, eliminating operator-to-operator variation. The satin chrome finish reduces glare under shop lighting. Machinists, tool-and-die makers, and quality-control technicians use this instrument for verifying tap, reamer, and end mill geometry.\u003c\/p\u003e\n\u003cp\u003eThe 52497 is used in machine shops, tool rooms, and manufacturing environments where 5-flute cutting tools must be measured accurately. The V anvil geometry positions the tool so that the spindle contacts the cutting edge directly opposite the valley between two flutes, giving a true outer-diameter reading. It is appropriate for both incoming inspection of new tooling and wear monitoring of tools in service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range of 0.078 to 1 inch covers common 5-flute end mill and reamer sizes\u003c\/li\u003e\n  \u003cli\u003e0.0001 inch graduation for high-precision diameter readings\u003c\/li\u003e\n  \u003cli\u003eCarbide anvil and carbide spindle resist wear and maintain accuracy over extended use\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble delivers consistent contact pressure for repeatable measurements\u003c\/li\u003e\n  \u003cli\u003eV anvil geometry engineered specifically for 5-flute cutting tool measurement\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish reduces glare and resists corrosion\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for measuring 5-flute cutting tools such as taps, reamers, and end mills with an outer diameter between 0.078 and 1 inch.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument requires no installation. Before use, clean the anvil and spindle faces with a lint-free cloth and verify the zero setting against a known standard. Store the micrometer in its case with the spindle slightly open to prevent spring fatigue. Calibration should be performed by a qualified metrologist according to your facility's quality system requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes Measured\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnvil Type\u003c\/strong\u003e: V Anvil\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\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Nut Type\u003c\/strong\u003e: Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Mechanical\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: 52497\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540344176946,"sku":"52497","price":1060.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ac0d95b70b1a1544c97d99a6bc40e56.jpg?v=1785852813","url":"https:\/\/voomisupply.com\/products\/starrett-52497-v-anvil-micrometer-0-078-to-1-inch-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
