Built with aluminum oxide non-woven construction, the disc delivers consistent cut and finish without loading or glazing. It mounts via a Type R (TR) attaching system for fast, tool-free changeovers. Rated to 20,000 RPM, it suits high-speed angle grinders and die grinders commonly used in professional fab shops, welding environments, and industrial maintenance settings. The Very Fine grade makes it appropriate for light blending and pre-finishing passes rather than aggressive stock removal.\u003c\/p\u003e\u003cp\u003eThis disc is used in applications where surface prep, weld blending, or scratch refinement is required on metal substrates. The non-woven aluminum oxide construction conforms slightly to contours, making it useful for work on irregular or curved surfaces. It is a standard tool for fabricators, maintenance technicians, and metalworkers who need repeatable surface finish results with quick media changes between passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType R (TR) quick-change attaching system for fast, secure mounting and removal\u003c\/li\u003e\n\u003cli\u003eAluminum oxide non-woven abrasive material resists loading and maintains consistent cut rate\u003c\/li\u003e\n\u003cli\u003eVery Fine grade suitable for blending, conditioning, and pre-finishing operations\u003c\/li\u003e\n\u003cli\u003e20,000 RPM maximum speed rating compatible with common high-speed grinders and die grinders\u003c\/li\u003e\n\u003cli\u003eBlue disc with white button for easy grade and type identification on the job\u003c\/li\u003e\n\u003cli\u003eSeries RC construction for dependable performance in surface conditioning tasks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Type R (TR) quick-change disc backing pads on angle grinders and die grinders rated to accept 3-inch quick-change abrasive discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounting and removal is performed by a metalworker or fabricator using a compatible Type R backing pad — no tools required for the disc change itself. Always ensure the grinder or die grinder is powered off and unplugged before changing discs. Verify the tool spindle speed does not exceed the 20,000 RPM disc rating before operation. Inspect the disc for damage before each use and discard any disc that shows tears, unraveling, or delamination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 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: Very Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Type R (TR)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: RC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STANDARD ABRASIVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000046879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51540298563890,"sku":"7000046879","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e5cd3d2e18fe41511af8bd4a86d45de.jpg?v=1785851459","url":"https:\/\/voomisupply.com\/products\/standard-abrasives-7000046879-quick-change-disc-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
