Built with a ceramic alumina abrasive on a fiberglass backing, this disc delivers consistent cut rates and extended service life under heavy grinding loads. It runs at a maximum of 12,000 RPM and is sized at 5 inches in diameter with a 7\/8 inch arbor hole, fitting standard angle grinders used in fabrication, weld prep, and surface conditioning work. At 60 grit, it falls in the medium grade range, making it well suited for blending welds and removing mill scale without excessive stock removal.\u003c\/p\u003e\u003cp\u003eThis flap disc is designed for use in metal fabrication shops, maintenance and repair operations, and structural steel work environments. The Type 27 flat profile is the standard choice when working on flat or low-contour surfaces where a depressed-center disc would contact the workpiece at a low angle. It is commonly deployed by ironworkers, pipefitters, welders, and industrial maintenance technicians who need a reliable disc for weld blending and surface prep on ferrous and non-ferrous metals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic alumina abrasive material for consistent cut rate and longer disc life\u003c\/li\u003e\n\u003cli\u003eType 27 flat profile suited for flat surface grinding and weld blending\u003c\/li\u003e\n\u003cli\u003e60 grit medium grade for weld removal, scale removal, and surface conditioning\u003c\/li\u003e\n\u003cli\u003eFiberglass backing provides structural rigidity under lateral load\u003c\/li\u003e\n\u003cli\u003e12,000 RPM maximum speed rating compatible with standard angle grinders\u003c\/li\u003e\n\u003cli\u003eBlue disc color for quick visual identification in multi-disc environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eFits angle grinders with a 5 inch disc capacity and a 7\/8 inch arbor.

Always inspect the disc for cracks or damage before mounting, and confirm the tool's rated RPM meets or exceeds the disc's 12,000 RPM maximum. Ensure the grinder guard is in place before operation. Do not exceed the disc's rated speed or use the disc for cutting operations unless specifically rated for that purpose.\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\u003eCenter Hole Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlap Disc Type\u003c\/strong\u003e: Type 27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Alumina\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Fiberglass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Arbor Hole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 12,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steels, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R828\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.6 inches x 6.5 inches x 6.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 66623399213\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543531290930,"sku":"66623399213","price":139.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc0fb9927f218ef9da54ef7bab047b09.jpg?v=1785919951","url":"https:\/\/voomisupply.com\/products\/norton-66623399213-flap-disc-60-grit-type-27-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
