Built with zirconia alumina abrasive at 60 grit (medium grade), it delivers consistent cut rate and extended disc life compared to standard aluminum oxide flap discs. The coated abrasive construction uses overlapping flaps bonded to a fiberglass backing plate, which provides flexibility and controlled stock removal. At 3 inches in diameter with a Quick-Change Type R attachment, this disc mounts without tools on compatible right-angle grinders and die grinders. It is rated to 30,000 RPM for safe operation at high tool speeds. Metalworkers, fabricators, and maintenance technicians use this disc for weld blending, deburring, and surface conditioning.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is suited for use in fabrication shops, field maintenance, and manufacturing environments where rapid material removal on steel, stainless steel, and other ferrous metals is required. The 3-inch diameter and Quick-Change Type R mount make it a practical choice for tight-access grinding and finishing work where larger discs cannot reach. The medium 60-grit cut level handles initial weld cleanup as well as transition work before moving to finer finishing grits. Typical users include welders, pipefitters, and general metalworking professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina abrasive for high cut rate and long disc life on metal\u003c\/li\u003e\n  \u003cli\u003e60 grit medium grade suitable for weld blending, deburring, and surface prep\u003c\/li\u003e\n  \u003cli\u003eType 27 flat profile designed for surface grinding applications\u003c\/li\u003e\n  \u003cli\u003eFiberglass backing provides durability and controlled flex during use\u003c\/li\u003e\n  \u003cli\u003eQuick-Change Type R attachment allows tool-free disc changes on compatible grinders\u003c\/li\u003e\n  \u003cli\u003e30,000 RPM maximum speed rating supports high-speed die grinder operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with right-angle grinders and die grinders equipped with a Quick-Change Type R arbor system.

Always power down and disconnect the grinder before mounting or removing a flap disc. Confirm the tool's no-load RPM does not exceed the disc's 30,000 RPM maximum rating. Inspect the disc for damage before each use and never use a cracked or delaminated disc.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\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: 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: Quick-Change Type R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 30,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.75 x 3.38 x 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.021 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: 77696090172\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538276679986,"sku":"77696090172","price":111.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/002c1f05813c1c0870f7b8fa798fc79d.jpg?v=1785821486","url":"https:\/\/voomisupply.com\/products\/norton-77696090172-flap-disc-60-grit-zirconia-alumina-type-27","provider":"Voomi Supply","version":"1.0","type":"link"}
