Measuring 4.5 inches in diameter with a 5\/8-11 arbor hole, it mounts directly to standard angle grinders. The abrasive material is aluminum oxide, rated for a maximum of 13,300 RPM, and the disc is backed with fiberglass for rigidity during use. At a fine grade, it is suited for finishing passes where surface quality matters more than aggressive stock removal. The green non-woven construction provides consistent cut rate as the disc wears.\u003c\/p\u003e\u003cp\u003eThis flap disc is intended for use on angle grinders in fabrication shops, maintenance facilities, and field service environments. It is appropriate for finishing welds, blending surface irregularities, and preparing metal surfaces for coating or inspection. The fine grade and non-woven abrasive construction make it a common choice when a smooth, consistent finish is required on steel, stainless steel, or similar hard materials. It is typically used by metal fabricators, pipefitters, ironworkers, and maintenance technicians.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 27 flat profile for surface grinding and blending applications\u003c\/li\u003e\n\u003cli\u003eAluminum oxide non-woven abrasive at fine grade for controlled surface finishing\u003c\/li\u003e\n\u003cli\u003eFiberglass backing provides structural support and consistent disc geometry under load\u003c\/li\u003e\n\u003cli\u003e5\/8-11 arbor attachment fits most standard angle grinders\u003c\/li\u003e\n\u003cli\u003e13,300 RPM maximum speed rating for safe operation on common grinder models\u003c\/li\u003e\n\u003cli\u003e4.5 inch diameter offers good coverage on flat and mildly contoured surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use flap disc for standard 4.5 inch angle grinders equipped with a 5\/8-11 spindle thread.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by personnel familiar with angle grinder safety practices. Always confirm the grinder spindle speed does not exceed the 13,300 RPM rating of the disc before mounting. Power down and disconnect the grinder from its power source before mounting or removing the disc. Inspect the disc for damage prior to each use and follow applicable ANSI B11 and grinder manufacturer guidelines for abrasive wheel mounting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Hole Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlap Disc Type\u003c\/strong\u003e: Type 27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Non-Woven\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Fiberglass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Green\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.5 x 4.5 x 0.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: 77696097546\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540357316914,"sku":"77696097546","price":37.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd730a37be384e04e52ac05990a34be6.jpg?v=1785853236","url":"https:\/\/voomisupply.com\/products\/norton-77696097546-flap-disc-4-5in-type-27-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
