It runs at a maximum speed of 12,000 RPM and carries a 60 grit, medium grade abrasive surface suited for blending, grinding, and finishing on metal and weld seams. The fiberglass backing plate provides rigidity and durability under heavy load. At 5 inches in diameter with a 5\/8-11 arbor attachment, it fits the most common angle grinder spindle size used in fabrication and metalworking trades. Weighing 0.43 pounds, the disc is lightweight without sacrificing abrasive performance.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is used in metal fabrication shops, structural steel work, welding cleanup, and general grinding applications. The Type 29 conical design positions the abrasive at an angle to the workpiece, making it effective for stock removal on flat and contoured surfaces. It is commonly installed and used by welders, pipefitters, ironworkers, and maintenance mechanics who require consistent cut rate and surface finish in a single disc. The blue fiberglass-backed construction is typical for production grinding environments where disc life and heat resistance matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 29 conical flap design for aggressive stock removal and surface blending\u003c\/li\u003e\n  \u003cli\u003eZirconia alumina abrasive material delivers long service life on steel and alloys\u003c\/li\u003e\n  \u003cli\u003e60 grit medium grade balances cut rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eFiberglass backing plate resists flex and heat during extended use\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 arbor attachment fits standard angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003eRated to 12,000 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on standard 5 inch angle grinders equipped with a 5\/8-11 threaded spindle.

Always verify the grinder free speed does not exceed the 12,000 RPM disc rating before use. Inspect the disc for cracks or delamination before each use and discard if damaged. Use appropriate PPE including face shield, gloves, and hearing protection per ANSI B11 and OSHA grinding 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: 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 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: 12,000\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: 13.2 x 5.7 x 0.61 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.43 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: 66623399191\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538322620722,"sku":"66623399191","price":194.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2126565c0da27bbf8c78a927cab09cc6.jpg?v=1785822980","url":"https:\/\/voomisupply.com\/products\/norton-66623399191-flap-disc-60-grit-type-29-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
