It features an 80 grit, medium-grade abrasive on a cloth backing, which provides durability and consistent cut throughout the life of the disc. The conical Type 29 geometry allows for better contact on flat and contoured surfaces, making it well suited for grinding, weld blending, and surface preparation work. Rated at 13,300 RPM, this disc is built for use on standard 4.5-inch angle grinders. It is installed and used by metal fabricators, pipefitters, ironworkers, and general industrial maintenance trades.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is intended for grinding and surface conditioning on steel, stainless steel, and other ferrous metals in both fabrication shop and field environments. The 7\/8 inch arbor hole fits the majority of 4.5-inch angle grinders in common use. The zirconia alumina abrasive delivers a self-sharpening cutting action that extends disc life compared to standard aluminum oxide discs. Typical applications include weld removal, edge deburring, and surface blending prior to coating or inspection. This is a single-disc package sold in a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 29 conical flap geometry for flat and contoured surface grinding\u003c\/li\u003e\n  \u003cli\u003eZirconia alumina abrasive provides self-sharpening, extended-life cutting action\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade suitable for weld blending and aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eCloth backing delivers flexibility and durability under load\u003c\/li\u003e\n  \u003cli\u003e13,300 RPM maximum speed rating compatible with standard 4.5-inch angle grinders\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch arbor hole with standard arbor attachment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement flap disc for 4.5-inch angle grinders with a 7\/8 inch arbor hole accepting Type 29 flap discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by personnel trained in the use of angle grinders and abrasive products. Always power down and disconnect the grinder before mounting or removing a disc. Verify that the grinder RPM rating meets or exceeds the disc maximum RPM rating of 13,300 RPM before use. Inspect the disc for damage before each use and follow applicable ANSI B7.1 and OSHA abrasive wheel safety requirements.\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: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlap Disc Type\u003c\/strong\u003e: Type 29\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\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: Zirconia Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 pounds\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\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: 66254461164\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541753037106,"sku":"66254461164","price":101.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d887bef7c06d5e25ff26906abd065c92.jpg?v=1785884052","url":"https:\/\/voomisupply.com\/products\/norton-66254461164-flap-disc-80-grit-type-29-4-5-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
