It covers a measurement range of 0.05 to 0.6 inches with a resolution of 0.0001 inch and an accuracy of 4 micrometers (0.0002 inch). Both the anvil and spindle are carbide-tipped for durability against tool-steel contact surfaces. A ratchet stop thimble ensures consistent measuring force across repeated readings. Built-in data output allows integration with SPC software or data loggers for in-process quality control. The satin chrome finish reduces glare and corrosion on the shop floor. This instrument is used by machinists and tool-room technicians performing precision inspection.\u003c\/p\u003e\n\u003cp\u003eThe 314-351-30 is suited for tool-room inspection and production-floor QC in machine shops, tooling departments, and manufacturing facilities. It measures 3-flute cutting tool geometries that conventional micrometers cannot accurately read due to their flat anvil design. The V-anvil contacts two flute lands simultaneously while the spindle contacts the third, delivering a true minor diameter reading. Applications include inspection of solid carbide end mills, threading taps, and multi-flute rotary cutting tools where precise diameter verification is required before and after grinding operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range: 0.05 to 0.6 inches for 3-flute cutting tools\u003c\/li\u003e\n  \u003cli\u003eResolution of 0.0001 inch with digital electronic readout\u003c\/li\u003e\n  \u003cli\u003eAccuracy to 4 micrometers (0.0002 inch)\u003c\/li\u003e\n  \u003cli\u003eCarbide anvil and spindle for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble for repeatable, consistent measuring force\u003c\/li\u003e\n  \u003cli\u003eData output port for SPC and statistical process control integration\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish for reduced glare and corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for measurement of 3-flute cutting tools with minor diameters from 0.05 to 0.6 inches.

Store the micrometer in its provided case when not in use to protect the carbide contact surfaces and the electronic display. Calibrate against the included setting standard before use and periodically during extended measurement sessions. Power is supplied by one SR44 battery; replace the battery promptly when the low-battery indicator appears to maintain accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.05 to 0.6 inches\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: 4 micrometers (0.0002 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.0001 inch \/ 0.001 inch \/ 0.01 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Electronic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes Measured\u003c\/strong\u003e: 3\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\u003eSpindle Diameter\u003c\/strong\u003e: 6.35 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eData Output\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery\u003c\/strong\u003e: SR44\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Battery, Box, Key, Setting Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 314-351-30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51559103267122,"sku":"314-351-30","price":902.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5eed64cddc8adc2f39a3c3ff02fcaaf7.jpg?v=1786427674","url":"https:\/\/voomisupply.com\/products\/mitutoyo-314-351-30-electronic-v-anvil-micrometer-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
