Built with a non-woven aluminum oxide construction in a fine grade, this disc is suited for light deburring, surface conditioning, blending, and finishing on metal and other hard surfaces. It runs at a maximum of 25,000 RPM and mounts in seconds without tools, making it a practical choice for HVAC fabricators, pipefitters, and sheet metal technicians who need consistent surface prep without swapping out entire tool assemblies.\u003c\/p\u003e\n\u003cp\u003eThis disc fits applications where controlled material removal and surface blending are required without aggressive stock removal. Common install and fabrication scenarios include cleaning weld seams, prepping metal surfaces before brazing or bonding, and light rust or scale removal on HVAC components, ductwork, and pipe connections. The non-woven construction conforms to irregular surfaces and reduces the risk of gouging on thinner-gauge materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-inch disc diameter sized for compact angle grinders and Roloc-style tools\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive material for durable performance on ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eNon-woven construction conforms to irregular and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eFine grade for surface blending and finishing rather than aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 25,000 RPM\u003c\/li\u003e\n  \u003cli\u003eTR (Type III) attaching system for tool-free quick-change mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Roloc TR (Type III) quick-change disc holders and tools.

Always confirm the tool RPM rating meets or exceeds the disc maximum of 25,000 RPM before use. Inspect the disc for tears or damage before each use and do not use damaged discs. Follow ANSI B7.1 and applicable shop safety standards when operating abrasive tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Non-Woven\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 25,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: TR (Type III)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuick Change Compatibility\u003c\/strong\u003e: Roloc TR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Green\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SE-DR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100034847\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51540185121074,"sku":"7100034847","price":645.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a5786099d00dfe67b23b71bc329199a.jpg?v=1785848365","url":"https:\/\/voomisupply.com\/products\/3m-7100034847-quick-change-disc-2-in-aluminum-oxide-fine","provider":"Voomi Supply","version":"1.0","type":"link"}
