It covers a measurement range of 0.5000 to 0.8000 inches and delivers an accuracy of 0.0002 inches. The set features solid carbide measuring anvils and a ratchet stop thimble, which applies consistent measuring pressure and reduces operator error. Machinists, tool and die makers, and quality control technicians use this type of instrument for close-tolerance inspection work in manufacturing and production environments. The included extension rod extends reach up to 6.0000 inches for deeper bore access.\u003c\/p\u003e\u003cp\u003eThis inside micrometer set is suited for precision measurement in machine shops, tool rooms, and inspection departments where internal diameter verification is required. The self-aligning and self-centering anvil design helps ensure repeatable readings without repositioning. The set comes complete with an extension rod, setting rings, spanner wrenches, and a wooden storage case, making it ready for immediate use at the bench or on the shop floor. Two micrometer heads are included to cover the stated range effectively.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide measuring anvils for wear resistance and extended service life\u003c\/li\u003e\n\u003cli\u003eRatchet stop thimble provides consistent measuring force on each reading\u003c\/li\u003e\n\u003cli\u003eSelf-aligning and self-centering design improves repeatability in bore measurement\u003c\/li\u003e\n\u003cli\u003eOne extension rod included, with maximum extension rod length of 6.0000 inches\u003c\/li\u003e\n\u003cli\u003eSetting ring diameter of 0.6500 inches included for calibration reference\u003c\/li\u003e\n\u003cli\u003eComplete kit includes extension rod, setting rings, spanner wrenches, and wooden case\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inside micrometer set for precision internal diameter measurement applications in manufacturing, inspection, and tool room environments where 0.5000 to 0.8000 inch bore ranges are required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInside micrometers are typically used by machinists and metrology technicians and require no installation in the traditional sense. Before use, verify calibration using the included setting ring and zero the instrument accordingly. Keep the measuring faces clean and free of debris to maintain accuracy. Store the instrument in the provided wooden case when not in use to protect the carbide anvils and precision components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.5000 to 0.8000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Type\u003c\/strong\u003e: Ratchet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGage Depth\u003c\/strong\u003e: 2.3600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extension Rod Length\u003c\/strong\u003e: 6.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetting Ring Diameter\u003c\/strong\u003e: 0.6500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Extension Rods\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Heads\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Setting Rings Included\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Extension Rod, Setting Rings, Spanner Wrenches, Wooden Case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.7 pounds\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: 10-720-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51699253346610,"sku":"10-720-1","price":618.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f834efe933a44bbc68809a48708713bb.jpg?v=1788374182","url":"https:\/\/voomisupply.com\/products\/spi-10-720-1-inside-micrometer-set-0-5-to-0-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
