At 320 grit, this disc falls in the extra-fine grade range, making it well-suited for final sanding passes, surface prep before finishing, and light stock removal. The aluminum oxide abrasive grain is bonded to a B-weight paper backing, which provides flexibility for contoured surfaces while maintaining enough stiffness for flat-stock work. Each pack contains 100 discs, giving service technicians and shop operators a consistent supply for production or maintenance tasks.\u003c\/p\u003e\n\u003cp\u003eThis disc is part of the A275 series and is intended for use with 6-inch PSA random-orbital or disc sanders equipped with a 6-hole vacuum dust extraction pattern. It is commonly used in woodworking, automotive bodywork prep, metal finishing, and composite surface preparation. The PSA backing adheres directly to a foam or hard-pad platen without requiring hook-and-loop hardware, making disc changes fast in high-volume production environments. Suitable for both shop and field use where a fine, consistent scratch pattern is required before coating or sealing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e320 grit aluminum oxide grain for extra-fine surface finishing\u003c\/li\u003e\n  \u003cli\u003eB-weight paper backing provides flexibility across flat and contoured workpieces\u003c\/li\u003e\n  \u003cli\u003ePSA adhesive mount for fast, tool-free disc changes on compatible platens\u003c\/li\u003e\n  \u003cli\u003e6 vacuum holes for dust extraction compatibility with standard 6-hole sanding pads\u003c\/li\u003e\n  \u003cli\u003ePack of 100 discs for sustained production or service use\u003c\/li\u003e\n  \u003cli\u003ePart of the A275 series for consistent grit-to-grit performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 6-inch PSA sanding pads and random-orbital or disc sanders equipped with a 6-hole dust extraction pattern.

Align vacuum holes with the pad holes before pressing the disc firmly onto the platen. Operate the sander at the speed recommended by the tool manufacturer for the workpiece material. Worn or glazed discs should be replaced promptly to avoid heat buildup and surface damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 6 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: Paper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: PSA (Pressure-Sensitive Adhesive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Vacuum Holes\u003c\/strong\u003e: 6\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: Natural\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Discs per Pack\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A275\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.4 pounds\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: 66261131507\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51712905937202,"sku":"66261131507","price":130.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30d397daad8ccba1a0f7471628e49779.jpg?v=1788489291","url":"https:\/\/voomisupply.com\/products\/norton-66261131507-psa-disc-320-grit-6-inch-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
