Running at up to 10,000 RPM on a standard angle grinder or disc grinder, this coated abrasive uses a resinoid bond over a fiber backing to deliver consistent cut rates through the life of the disc. The 120-grit fine grade makes it well suited for finishing passes, blending, and light deburring where controlled stock removal is required. The 7\/8-inch arbor hole fits common grinder spindles without adapters.\u003c\/p\u003e\u003cp\u003eThis disc is used in fabrication shops, maintenance and repair operations, and field metalworking applications. It is appropriate for use on ferrous metals, stainless steel, and similar hard substrates where a fine grit leaves a clean surface before coating or inspection. Licensed tradespeople including welders, pipefitters, and ironworkers typically reach for this disc during post-weld cleanup and before surface treatment processes. The orange disc color corresponds to the ceramic alumina Series F980 product line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic alumina abrasive grain for high cut rate and longer disc life compared to aluminum oxide\u003c\/li\u003e\n\u003cli\u003e120-grit fine grade suited for finishing, blending, and light deburring\u003c\/li\u003e\n\u003cli\u003eResinoid bond over fiber backing provides durability under load\u003c\/li\u003e\n\u003cli\u003e7\/8-inch arbor hole fits standard angle grinder spindles\u003c\/li\u003e\n\u003cli\u003eRated to 10,000 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eCoated abrasive construction delivers consistent surface finish across the disc face\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on angle grinders and disc grinders fitted with a 5-inch backup pad and a 7\/8-inch spindle arbor.

Always power down and disconnect or de-energize the grinder before mounting or removing a disc. Inspect the disc for cracks, nicks, or delamination before each use and discard any damaged disc immediately. Wear appropriate PPE including a face shield, hearing protection, and gloves during grinding operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic 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: Fiber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Arbor Hole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 10,000\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: F980\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaged Dimensions\u003c\/strong\u003e: 5.25 inches x 5.25 inches x 2 inches\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: 66254409084\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544159715634,"sku":"66254409084","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd5eed7f76f2f0a579e51e41ae3afee3.jpg?v=1785924917","url":"https:\/\/voomisupply.com\/products\/norton-66254409084-fiber-disc-120-grit-5-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
