It carries a 40-grit coarse rating and is rated to 13,300 RPM, making it suitable for heavy grinding, weld blending, and surface prep on steel and other metals. The cloth backing provides durability and flexibility that allows the disc to conform to contoured or flat work surfaces. This disc is a standard item in fabrication, maintenance, and construction trades where fast stock removal is required.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is used in metal fabrication shops, structural steel work, pipeline work, and general maintenance applications. The Type 29 conical design presents the abrasive at an angle, concentrating grinding pressure and increasing material removal rate compared to flat Type 27 discs. It is particularly effective for blending welds, removing mill scale, and preparing surfaces for coating or further finishing. Trade professionals running 4.5-inch angle grinders will find this a direct-fit option for standard arbor configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40-grit coarse abrasive for fast material removal and weld blending\u003c\/li\u003e\n  \u003cli\u003eZirconia alumina abrasive material delivers long service life on steel and ferrous metals\u003c\/li\u003e\n  \u003cli\u003eType 29 conical geometry increases grinding pressure for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eCloth backing resists tearing and provides flexibility on contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eRated to 13,300 RPM for use with standard 4.5-inch angle grinders\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch center hole fits standard arbor attachments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 4.5-inch angle grinders equipped with a standard 7\/8-inch arbor attachment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified operator following the grinder and disc manufacturer guidelines. Confirm the grinder RPM rating meets or does not exceed the disc maximum of 13,300 RPM before mounting. Always power down and disconnect the tool before changing discs, and verify the disc is properly seated and the guard is in place before operation. Inspect the disc for cracks or damage prior to each use and discard any disc that shows signs of delamination or impact damage.\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: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\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\u003eMaximum RPM\u003c\/strong\u003e: 13,300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.109 pounds\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: 66254461161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538788352306,"sku":"66254461161","price":101.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f8156294fd147f228e063b8fbba340a.jpg?v=1785826603","url":"https:\/\/voomisupply.com\/products\/norton-66254461161-flap-disc-40-grit-type-29-zirconia","provider":"Voomi Supply","version":"1.0","type":"link"}
