The disc measures 4.5 inches in diameter with a 5\/8-11 threaded arbor hole for direct mounting to standard angle grinders. Abrasive material is zirconia alumina, an 80-grit medium-grade coating bonded to overlapping fiberglass-backed flaps in a high-density configuration. The fiberglass backing resists flex fatigue under load, and the disc is rated to a maximum of 13,000 RPM. Sold in packs of 5, this disc is a common consumable choice for fabricators, ironworkers, pipefitters, and maintenance welders working in metal fab and field repair applications.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is suited for flat grinding and light stock removal on mild steel, structural steel, and stainless steel workpieces. The Type 27 flat profile allows the disc to sit parallel to the work surface, making it effective for surface conditioning, weld blending, and deburring on plate, pipe, and structural shapes. The high-density flap construction extends disc life compared to standard-density alternatives, which reduces changeover frequency during production runs. It is compatible with 5\/8-11 spindle angle grinders — the standard thread found on most 4.5-inch grinder models in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina abrasive for durable performance on ferrous and stainless steel\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade for weld blending, deburring, and surface conditioning\u003c\/li\u003e\n  \u003cli\u003eType 27 flat profile for surface and flat-angle grinding applications\u003c\/li\u003e\n  \u003cli\u003eFiberglass backing resists flex fatigue and heat buildup during use\u003c\/li\u003e\n  \u003cli\u003eHigh-density flap construction extends usable disc life\u003c\/li\u003e\n  \u003cli\u003eRated to 13,000 RPM for use on standard 4.5-inch angle 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 arbor.

Verify that the grinder's no-load RPM rating meets or exceeds the disc's 13,000 RPM maximum before use. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation. Do not use a damaged, cracked, or loaded disc, and inspect each disc prior to mounting.\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 27\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\u003eBacking Weight\u003c\/strong\u003e: X\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\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steels, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: High Density\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R822\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N03529\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691950571826,"sku":"N03529","price":195.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9461ed2fd605a19a0b41032ff8f65553.jpg?v=1788291334","url":"https:\/\/voomisupply.com\/products\/value-collection-n03529-flap-disc-80-grit-type-27-4-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
