Built around a fiberglass backing plate, the disc uses zirconia alumina abrasive grains in an 80-grit medium-grade configuration, which balances cut rate with surface finish. The threaded arbor hole accepts a standard 5\/8-11 spindle, allowing direct mounting on most angle grinders without additional hardware. Rated to 13,000 RPM, it is suited for sustained grinding and blending operations in fabrication, weld preparation, and surface conditioning work performed by metalworkers, pipefitters, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is intended for use with 4.5-inch angle grinders in both shop and field environments. The Type 29 conical geometry presents the abrasive at an angle to the workpiece, concentrating contact at the leading edge of the flaps for faster stock removal compared to a flat Type 27 profile. Typical applications include weld seam grinding, deburring, and blending on structural steel, stainless fabrications, and titanium components. The R980P series designation indicates this disc is part of a performance-oriented product line aimed at industrial and trade users who require consistent cut life over extended use cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 29 conical profile for aggressive stock removal at low-to-moderate angles\u003c\/li\u003e\n  \u003cli\u003eZirconia alumina abrasive grain rated for use on steels, stainless steel, and titanium\u003c\/li\u003e\n  \u003cli\u003e80-grit medium grade balances material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eFiberglass backing provides structural rigidity under heavy pressure and lateral loads\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded arbor hole mounts directly to standard angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003e13,000 RPM maximum speed rating supports full-speed operation on most 4.5-inch grinders\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 5\/8-11 threaded spindle.

Confirm the grinder's no-load RPM rating does not exceed the disc's 13,000 RPM maximum before mounting. Power down and disconnect the grinder from its power source before attaching or removing the disc. Always inspect the disc for cracks or damage prior to use and ensure the guard is properly in place before operating.\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 Thread 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: 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: Fiberglass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Threaded Arbor Hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steels, Stainless Steel, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Orange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R980P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.8 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: 66261183493\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538882920754,"sku":"66261183493","price":24.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/008c8ee9728201f45cee3c79e75ff6a2.jpg?v=1785828821","url":"https:\/\/voomisupply.com\/products\/norton-66261183493-flap-disc-80-grit-type-29-4-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
