Built around a friction thimble design with solid rods, the set delivers accuracy to 0.0001 inches per reading. The satin chrome finish resists glare and corrosion under shop conditions. Hardened and ground anvils provide repeatable contact geometry across the full measurement range. Insulated rods marked with their length speed up rod selection during measurement. This set is used by machinists, tool-and-die workers, and precision measurement technicians working in manufacturing, maintenance, and quality control environments.\u003c\/p\u003e\u003cp\u003eThe 50546 is suited for shop floor and inspection room use where internal measurements of bores, cylinders, and housings are required. The 10 extension rods extend the range from 2 to 12 inches, making the set appropriate for a wide variety of workpiece sizes. Quick-reading figures on the thimble reduce reading errors during high-volume inspection. A fitted case is included for organized storage and transport of rods and the measuring head.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range of 2 to 12 inches using 10 included solid extension rods\u003c\/li\u003e\n\u003cli\u003eAccuracy to 0.0001 inches for precise bore and diameter readings\u003c\/li\u003e\n\u003cli\u003eFriction thimble provides consistent measuring force and repeatable results\u003c\/li\u003e\n\u003cli\u003eHardened and ground anvils for reliable contact and long service life\u003c\/li\u003e\n\u003cli\u003eInsulated rods marked with length for fast identification and rod changes\u003c\/li\u003e\n\u003cli\u003eQuick-reading figures on the thimble scale reduce operator error\u003c\/li\u003e\n\u003cli\u003eSatin chrome finish minimizes glare and resists corrosion\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose mechanical inside micrometer set for use in standard machining, manufacturing, and precision inspection applications where internal bore measurements between 2 and 12 inches are required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInside micrometers are installed and used by machinists and metrology technicians; no permanent mounting is required. Before use, verify that all contact surfaces and rods are clean and free of debris to avoid measurement error. Store extension rods in the provided case to prevent damage to the hardened anvil surfaces. Follow shop calibration procedures and applicable metrology standards to maintain measurement traceability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 2 to 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTravel\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRod Type\u003c\/strong\u003e: Solid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Friction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Extension Rods\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Measuring rods, fitted case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.313 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 50546\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540266189106,"sku":"50546","price":636.83,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9709678f2620f97dc17f01c11f75f5a.jpg?v=1785850723","url":"https:\/\/voomisupply.com\/products\/starrett-50546-inside-micrometer-set-2-to-12-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
