It features a 6-inch diameter with a 7\/8-inch arbor hole and runs at a maximum of 10,200 RPM. The fiberglass backing provides structural rigidity under load, while the zirconia alumina abrasive delivers consistent stock removal at 60 grit (medium grade). This disc is suited for angle grinder use in fabrication shops, field welding operations, and metal finishing work performed by ironworkers, pipefitters, and general metalworkers.\u003c\/p\u003e\u003cp\u003eThe Type 29 conical shape positions the abrasive face at an angle to the workpiece, which increases surface contact and improves material removal rates compared to a flat Type 27 disc. This geometry makes the 66254491777 well suited for weld blending, deburring, and surface prep on mild steel, stainless steel, and similar ferrous materials. The blue fiberglass backing resists heat buildup and flexing during extended grinding passes. Minimum order quantity is 10 units, sold individually per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 29 conical profile for aggressive stock removal and weld blending\u003c\/li\u003e\n\u003cli\u003eZirconia alumina abrasive for long-lasting cut rate on ferrous metals\u003c\/li\u003e\n\u003cli\u003e60 grit medium grade balances material removal with surface finish\u003c\/li\u003e\n\u003cli\u003eFiberglass backing provides rigidity and heat resistance under load\u003c\/li\u003e\n\u003cli\u003e10,200 RPM maximum speed rating for standard 6-inch angle grinders\u003c\/li\u003e\n\u003cli\u003e7\/8-inch arbor hole fits standard angle grinder spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement flap disc for 6-inch angle grinders accepting a 7\/8-inch arbor attachment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of flap discs should be performed by qualified personnel familiar with angle grinder safety practices. Always power down and disconnect the grinder before mounting or removing a disc. Verify the tool spindle speed does not exceed the disc maximum RPM rating before operation. Operators should wear appropriate PPE including face shield, gloves, and hearing protection in accordance with applicable OSHA and ANSI B11 guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 6 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: 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: 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: Fiberglass\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: 10,200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6 inches L x 6 inches W x 0.88 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 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: 66254491777\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541741076786,"sku":"66254491777","price":101.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02aa812fbe744ab023e9cc4d7cb21f9f.jpg?v=1785883621","url":"https:\/\/voomisupply.com\/products\/norton-66254491777-flap-disc-60-grit-type-29-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
