It measures 10 inches in diameter and uses 40-grit zirconia alumina, a very coarse abrasive engineered to cut fast and resist heat buildup during extended grinding sessions. The Y-weight cloth backing provides high tensile strength and flexibility, allowing the disc to conform to slightly contoured work surfaces without tearing. This disc is part of the Norton R821 series and is a standard tool for fabrication shops, weld prep, and surface conditioning work performed by metalworkers, fabricators, and maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis disc is suited for use on large-diameter PSA-compatible disc grinders and sanders in industrial and commercial settings. The 40-grit coarse grade makes it appropriate for rapid stock removal, rust elimination, paint stripping, and weld seam blending. The flexible Y-weight cloth backing performs well on both flat and mildly curved surfaces. No vacuum holes are included, which is consistent with standard PSA-mount configurations where dust extraction is handled externally or not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e40-grit zirconia alumina abrasive for fast, aggressive cutting action\u003c\/li\u003e\n\u003cli\u003e10-inch diameter fits large PSA disc grinder platens\u003c\/li\u003e\n\u003cli\u003eY-weight cloth backing delivers high strength and flexibility\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive mount for quick disc changes\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — standard solid-face PSA configuration\u003c\/li\u003e\n\u003cli\u003eBlue disc color; part of the Norton R821 series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-mount PSA abrasive disc for 10-inch PSA-compatible disc grinders and sanders.

Before mounting, ensure the grinder or sander is fully powered down and unplugged. Clean the platen surface of any adhesive residue before applying the PSA disc to ensure full, even adhesion. Do not exceed the maximum RPM rating of the machine or use a disc that is damaged, delaminated, or improperly seated.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: Y\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R821\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 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: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66261138314\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542927638834,"sku":"66261138314","price":22.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e96be464997b4dc2d1759c8c9eb68c54.jpg?v=1785911254","url":"https:\/\/voomisupply.com\/products\/norton-66261138314-psa-disc-10-in-40-grit-zirconia-alumina","provider":"Voomi Supply","version":"1.0","type":"link"}
