It measures 4.5 inches in diameter with a 5\/8-11 arbor hole for direct mounting on standard angle grinders. The abrasive material is aluminum oxide in a coarse grade, suited for stock removal and surface prep tasks that demand a consistent, controllable cut. The fiberglass backing provides rigidity and dimensional stability during operation. Rated at 13,300 RPM, this disc is installed and used by metal fabricators, welders, pipefitters, and maintenance mechanics who need reliable material removal without switching tools.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is well-suited for flat and depressed-center grinding applications in fabrication shops, field welding operations, and general metalworking environments. The Type 27 flat profile is preferred when working on flat surfaces or inside corners where a low grinding angle is needed. The non-woven aluminum oxide construction delivers consistent scratch patterns and surface finish throughout the life of the disc. It is sold individually and fits standard 4.5-inch angle grinders commonly found on commercial and industrial job sites.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 27 flat profile for low-angle grinding on flat surfaces and inside corners\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive in coarse grade for aggressive stock removal and weld blending\u003c\/li\u003e\n  \u003cli\u003eNon-woven abrasive construction delivers consistent cut and uniform scratch pattern\u003c\/li\u003e\n  \u003cli\u003eFiberglass backing provides structural rigidity and stability at operating speed\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 arbor hole fits standard angle grinder spindles without adapters\u003c\/li\u003e\n  \u003cli\u003e13,300 RPM max rating compatible with common 4.5-inch angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 4.5-inch angle grinders equipped with a 5\/8-11 spindle thread, which is the industry-standard arbor size for this disc diameter class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified personnel familiar with angle grinder safety practices. Always confirm the grinder's rated RPM meets or exceeds the disc's 13,300 RPM maximum before mounting. Power down and disconnect the grinder from its power source before installing or removing the disc. Wear appropriate PPE including a face shield, safety glasses, and gloves, and ensure the work area is clear of flammable materials when grinding metal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 arbor\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: Coarse\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: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,300 RPM\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: 0.19 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: 77696097544\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542472917298,"sku":"77696097544","price":32.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/efa11733e4af3517e930173d843ab1ed.jpg?v=1785901196","url":"https:\/\/voomisupply.com\/products\/norton-77696097544-flap-disc-4-5-in-type-27-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
