Part of the F826P Series, this disc features a very coarse 36-grit abrasive on a resinoid-bonded, fiber-backed construction that delivers fast cutting action and durability under sustained load. The threaded arbor hole accepts a 5\/8-11 arbor attachment and is engineered for use with the Norton AVOS Speed-Lok back-up pad system. Rated to 13,000 RPM, it suits high-speed angle grinder applications common in fabrication, maintenance, and repair work. Licensed tradespeople and skilled fabricators working in metal shops, shipyards, and industrial maintenance environments rely on this disc type for surface conditioning and stock removal tasks.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for use on ferrous and non-ferrous metals where aggressive grinding, weld blending, or surface prep is required. The zirconia alumina abrasive self-sharpens during use, maintaining cut rate longer than standard aluminum oxide discs at comparable grit levels. It is appropriate for both flat and contoured surface work when mounted on a compatible rigid or semi-flexible back-up pad. The threaded arbor hole design allows quick disc changes without separate hardware, reducing downtime in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-inch diameter with 5\/8-11 threaded arbor hole for secure attachment\u003c\/li\u003e\n  \u003cli\u003e36-grit zirconia alumina abrasive for very coarse, high-speed stock removal\u003c\/li\u003e\n  \u003cli\u003eResinoid bond and fiber backing provide durability under heavy grinding loads\u003c\/li\u003e\n  \u003cli\u003eRated to 13,000 RPM for compatibility with standard angle grinders\u003c\/li\u003e\n  \u003cli\u003eSelf-sharpening zirconia alumina grain maintains consistent cut rate\u003c\/li\u003e\n  \u003cli\u003eCompatible with Norton AVOS Speed-Lok back-up pad system for fast disc changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the Norton AVOS Speed-Lok back-up pad.

Inspect the disc for cracks or damage before mounting — do not use a damaged disc. Ensure the back-up pad is rated for at least the disc's maximum RPM of 13,000 before operation. Follow ANSI B7.1 and applicable OSHA standards for abrasive wheel use, including the use of appropriate eye and face protection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 36\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: F826P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Threaded Arbor Hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Hole Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66261126557\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541220557106,"sku":"66261126557","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72c3530bfd56d56f566010cc3e7fafad.jpg?v=1785870253","url":"https:\/\/voomisupply.com\/products\/norton-66261126557-fiber-disc-5-in-36-grit-zirconia-alumina","provider":"Voomi Supply","version":"1.0","type":"link"}
