Part of the Norton R228 series, this disc measures 20 inches in diameter and uses 80-grit aluminum oxide abrasive on an X-weight cloth backing. The X-weight backing delivers high tensile strength for demanding material removal passes. The PSA mounting system allows fast disc changes on compatible 20-inch rotary sanders and floor grinders. At 0.72 pounds per disc, it is well-suited for flooring, industrial surface prep, and metal fabrication applications where a durable, medium-grit disc is required.\u003c\/p\u003e\u003cp\u003eThis disc is intended for use on large-format rotary or orbital floor sanding machines that accept 20-inch PSA-mount abrasives. It performs well on hardwood floor leveling, concrete surface preparation, and metal stock removal. The flexible cloth construction conforms slightly to minor surface irregularities, making it effective on broad panel and floor surfaces. Flooring contractors, metal fabricators, and industrial maintenance techs are the primary installers of this consumable abrasive product.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20-inch diameter fits large rotary floor sanders and grinders with PSA platens\u003c\/li\u003e\n\u003cli\u003e80-grit aluminum oxide abrasive for medium-grade material removal and surface leveling\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing provides high strength and resistance to tearing under load\u003c\/li\u003e\n\u003cli\u003eFlexible construction allows the disc to conform to minor surface contours\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive backing enables fast, tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — suited for machines without dust extraction ports at the platen\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a PSA-mount replacement disc for large rotary and orbital floor sanding machines that accept 20-inch abrasive discs with pressure-sensitive adhesive backing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by flooring contractors, metal fabricators, or industrial maintenance personnel using compatible PSA-platen sanding equipment. Before mounting, ensure the machine is powered off and unplugged. Clean the platen surface of adhesive residue from the previous disc before applying a new one to ensure full contact and proper adhesion. Operate the machine according to the manufacturer-recommended speed range for the disc diameter and backing weight.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\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: 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\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\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: 0.72 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: 66261136706\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539440468274,"sku":"66261136706","price":40.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5ac4ab841f3b125ad4b071643241521.jpg?v=1785840330","url":"https:\/\/voomisupply.com\/products\/norton-66261136706-psa-disc-80-grit-20-inches-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
