Built on a Y-weight cloth backing, this disc handles high-pressure grinding and finishing applications without flexing or tearing prematurely. The zirconia alumina abrasive grain self-sharpens under load, maintaining a consistent cut rate throughout the disc life. At 60 grit, it falls in the medium range, making it well-suited for blending welds, removing mill scale, and shaping surfaces before progressing to finer grits. The disc weighs 0.2 pounds and mounts via a PSA interface for quick, tool-free changes on compatible platens.\u003c\/p\u003e\u003cp\u003eThis disc is used in industrial and fabrication environments where stationary disc sanders, backstand grinders, or large-format PSA platen machines are in service. It is a common choice for metalworking shops, millwork operations, and maintenance facilities that require a durable, cloth-backed disc capable of sustained use under load. The flexible construction allows it to conform slightly to contoured workpieces. Typical users include metal fabricators, welders, woodworkers, and maintenance technicians working with ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZirconia alumina grain self-sharpens under grinding pressure for consistent material removal\u003c\/li\u003e\n\u003cli\u003eY-weight cloth backing provides high tear resistance under aggressive stock removal conditions\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive mount allows fast disc changes on compatible PSA platens\u003c\/li\u003e\n\u003cli\u003e60 grit medium cut rate suited for weld blending, scale removal, and surface shaping\u003c\/li\u003e\n\u003cli\u003eFlexible construction allows slight conformance to curved or irregular workpiece profiles\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — designed for solid platen use without dust extraction ports\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a PSA-mount replacement disc for stationary disc sanders and backstand grinders equipped with 12-inch solid PSA platens.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by trained abrasives or machine operators following equipment manufacturer guidelines. Power down and lock out the machine before removing the spent disc and cleaning the platen surface of adhesive residue. Press the new disc firmly from center to edge to eliminate air pockets and ensure full adhesive contact before resuming operation. Inspect the disc for damage before each use and do not exceed the maximum operating speed rated for the machine platen.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\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: 0.2 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: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66261138322\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541491024178,"sku":"66261138322","price":31.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83f661111c6c46a99527c05fdab100af.jpg?v=1785877699","url":"https:\/\/voomisupply.com\/products\/norton-66261138322-psa-disc-12-in-60-grit-zirconia-alumina","provider":"Voomi Supply","version":"1.0","type":"link"}
