At 5 inches in diameter with a 220 very fine grit aluminum oxide abrasive, this disc delivers controlled material removal and smooth surface refinement. The cloth backing with an X-weight construction provides flexibility and durability under load, making it suited for contour sanding and flat surface work. It belongs to the Norton R228 series and is installed by metalworkers, woodworkers, fabricators, and finishing technicians using PSA-compatible backup pads.\u003c\/p\u003e\u003cp\u003eThis disc is used in both shop and field finishing applications where a PSA mounting system is in place. The 220 grit rating makes it appropriate for fine finishing passes, pre-finish prep, and light stock removal on wood, painted surfaces, and soft metals. The flexible cloth backing allows the disc to conform slightly to curved or irregular surfaces, reducing gouging and uneven stock removal. No vacuum holes are included, so it is intended for solid backup pads without dust extraction ports.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e220 very fine grit aluminum oxide abrasive for controlled fine finishing\u003c\/li\u003e\n\u003cli\u003e5-inch diameter fits standard PSA backup pads\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing provides flexibility and tear resistance\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive mount for tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — designed for solid backup pad use\u003c\/li\u003e\n\u003cli\u003ePart of the Norton R228 series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 5-inch PSA (sticky-back) backup pads on random orbital sanders, disc sanders, and angle grinders equipped with a PSA pad.

Peel the liner from the adhesive backing and press the disc firmly and evenly onto a clean, dry PSA backup pad to ensure full adhesive contact. Avoid mounting on backup pads with vacuum holes, as the solid cloth backing is not perforated. Worn or contaminated backup pads reduce adhesion and disc performance; inspect the pad surface before each disc change.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 220\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very 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\u003eDisc Color\u003c\/strong\u003e: Brown\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: 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\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: 66254497792\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541791113522,"sku":"66254497792","price":236.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1eafc0bbc97075d3d71f659545d0c262.jpg?v=1785885073","url":"https:\/\/voomisupply.com\/products\/norton-66254497792-psa-disc-5-in-220-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
