Built on a flexible cloth backing with an X-weight designation, it delivers consistent cut and conformability on contoured and flat surfaces alike. The disc uses aluminum oxide abrasive at 320 grit, placing it in the extra fine grade range — suited for final sanding passes, between-coat finishing, and light stock removal on wood, metal, or composites. At 5 inches in diameter, it mounts directly to PSA-compatible backup pads without fasteners or hook-and-loop hardware.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in both residential and light industrial finishing applications. Common install scenarios include furniture and cabinetry finishing, automotive body prep, and metal surface conditioning before coating. The flexible cloth backing allows the disc to conform to slight surface variations, making it effective on assemblies where a rigid disc would leave uneven scratch patterns. No vacuum holes are present, so it is intended for use on solid backup pads rather than dust-collection systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e320 grit aluminum oxide abrasive for extra fine material removal and surface finishing\u003c\/li\u003e\n  \u003cli\u003ePressure-sensitive adhesive backing for tool-free, secure pad attachment\u003c\/li\u003e\n  \u003cli\u003eFlexible X-weight cloth backing conforms to curved and irregular surfaces\u003c\/li\u003e\n  \u003cli\u003e5-inch diameter fits standard PSA backup pads\u003c\/li\u003e\n  \u003cli\u003eNo vacuum holes — solid pad compatible\u003c\/li\u003e\n  \u003cli\u003eSeries R228 construction for consistent abrasive performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5-inch PSA-style backup pads on random orbital and rotary sanders configured for adhesive-mount discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by trade professionals and experienced finishers using standard PSA-compatible backup pads. Before mounting, ensure the backup pad surface is clean and free of adhesive residue from previous discs to maintain full contact and prevent premature release. Peel the liner from the adhesive side and press the disc firmly and evenly onto the pad before starting the tool. Discard and replace the disc when abrasive cutting action diminishes or if the disc shows signs of loading, tearing, or edge lifting.\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\u003eGrit\u003c\/strong\u003e: 320\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\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: X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Pressure-Sensitive Adhesive (PSA)\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\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R228\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0036 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: NORTON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66261135578\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539502072114,"sku":"66261135578","price":239.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9400cf20f030f310bc3dcacab24b106e.jpg?v=1785841947","url":"https:\/\/voomisupply.com\/products\/norton-66261135578-psa-disc-5-in-320-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
