Sold in a pack of 25, this disc measures 7 inches in diameter with a 7\/8-inch arbor hole and carries a 120-grit rating, placing it in the medium-fine range for controlled stock removal and surface blending. Aluminum oxide abrasive is well-suited to ferrous metals and general fabrication work, offering consistent cut rate and durability under sustained pressure. This disc is part of the Merit FX370 product line.\u003c\/p\u003e\n\u003cp\u003eThese fiber discs are used across metalworking, fabrication, and maintenance applications where a backing plate and angle grinder are the standard setup. The 7-inch diameter makes them appropriate for larger-format grinders used in structural steel work, pipe fabrication, weld blending, and surface conditioning on flat or moderately contoured workpieces. At 120 grit, they are suited for finish grinding and light deburring after heavier stock removal has been completed with a coarser disc.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive grain for consistent cut on ferrous metals and general fabrication surfaces\u003c\/li\u003e\n  \u003cli\u003e120-grit rating for medium-fine material removal, deburring, and weld blending\u003c\/li\u003e\n  \u003cli\u003e7-inch diameter with 7\/8-inch arbor hole for compatibility with standard large-format angle grinders\u003c\/li\u003e\n  \u003cli\u003eFiber backing provides rigidity and support when used with a firm backing pad\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 25 discs per order unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 7-inch angle grinders fitted with a compatible rigid or semi-flexible fiber disc backing pad.

Verify that the grinder's maximum RPM rating meets or exceeds the disc rating before mounting. Always power down and disconnect the grinder from its power source before changing discs. Inspect each disc for cracks or damage before use and never operate a damaged disc.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Line\u003c\/strong\u003e: Merit FX370\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 7 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\u003ePackage Quantity\u003c\/strong\u003e: 25 discs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: 666233-57289\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51346163204402,"sku":"666233-57289","price":63.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310537543.jpg?v=1782072611","url":"https:\/\/voomisupply.com\/products\/norton-666233-57289-aluminum-oxide-fiber-disc-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
