Built around an aluminum oxide abrasive bonded to a fiberglass backing plate, this disc delivers consistent cut and finish performance across its usable life. It measures 4.5 inches in diameter with a 5\/8-11 arbor hole, runs at a maximum of 13,300 RPM, and carries a medium grade rating suited to general-purpose surface conditioning. It is installed by metalworkers, fabricators, and maintenance technicians using standard angle grinders.\u003c\/p\u003e\u003cp\u003eThis flap disc is used in fabrication shops, maintenance facilities, and field metalworking applications where a Type 27 flat-profile disc is required. The non-woven construction provides a softer, more conformable cut compared to coated abrasive flap discs, making it appropriate for light material removal and surface prep on flat and contoured workpieces. The maroon-colored non-woven medium grade is a common choice for blending weld spatter and removing light oxidation without aggressive stock removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 27 flat-profile design for surface blending and finishing\u003c\/li\u003e\n\u003cli\u003eAluminum oxide non-woven abrasive construction for consistent, controlled cut\u003c\/li\u003e\n\u003cli\u003eFiberglass backing plate for rigidity and stability under load\u003c\/li\u003e\n\u003cli\u003e5\/8-11 arbor hole fits standard angle grinders directly\u003c\/li\u003e\n\u003cli\u003e13,300 RPM maximum rated speed for safe grinder operation\u003c\/li\u003e\n\u003cli\u003eMedium grade abrasive for general-purpose blending and light deburring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement flap disc for use with standard angle grinders accepting a 5\/8-11 arbor attachment and capable of operating at up to 13,300 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified metalworkers or maintenance technicians familiar with angle grinder operation and abrasive safety standards. Verify that the grinder speed rating does not exceed the 13,300 RPM maximum marked on the disc before mounting. Inspect the disc for damage before each use and never operate a damaged or delaminated flap disc. Follow ANSI B7.1 and applicable OSHA standards for abrasive wheel mounting and guarding.\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: Medium\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: Maroon\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: 0.19 pounds\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: 77696097545\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540421837106,"sku":"77696097545","price":31.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6869609fb250875064408f59e0203dee.jpg?v=1785854698","url":"https:\/\/voomisupply.com\/products\/norton-77696097545-flap-disc-4-5-in-type-27-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
