Each disc is constructed with a heavy vulcanized fibre backing and coated with aluminum oxide abrasive grains bonded with a tough, heat-resistant resin. This construction delivers fast cutting action and extended disc life under demanding conditions. At 50 grit, these discs remove material aggressively while leaving a surface ready for finishing or coating. Metalworkers, fabricators, and welding professionals reach for this disc when fast stock removal and durability both matter on the same job.\u003c\/p\u003e\u003cp\u003eThese discs are suited for weld grinding, blending, finishing, and deburring across a range of materials including most types of steel, fiberglass, and plastics. The 7\/8-inch arbor hole is the standard fit for most right angle grinder backing pads. Typical applications include structural steel fabrication, light sheet metal work, and general-purpose surface prep in both shop and field environments. The 3-pack format reduces downtime by keeping spares on hand during extended grinding sessions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e50 grit aluminum oxide abrasive for aggressive material removal on steel, fiberglass, and plastics\u003c\/li\u003e\n\u003cli\u003eHeavy vulcanized fibre backing provides rigidity and durability under load\u003c\/li\u003e\n\u003cli\u003eHeat-resistant resin bond resists glazing and maintains cutting performance during extended use\u003c\/li\u003e\n\u003cli\u003e4.5-inch diameter with 7\/8-inch arbor fits standard right angle grinder backing pads\u003c\/li\u003e\n\u003cli\u003eSuitable for weld grinding, blending, finishing, and deburring applications\u003c\/li\u003e\n\u003cli\u003eComes in a 3-pack to minimize tool downtime on the job\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on right angle grinders fitted with a standard 4.5-inch resin fibre disc backing pad with a 7\/8-inch arbor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDisc mounting and removal should be performed by a qualified operator with the grinder unplugged or the power source isolated. Inspect the disc for cracks, chips, or delamination before each use and discard any damaged disc immediately. Follow the grinder manufacturer's maximum RPM rating and confirm the disc speed rating meets or exceeds the tool's no-load speed before operation. Eye protection and appropriate PPE are required during grinding operations per applicable safety standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Vulcanized Fibre\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Heat-Resistant Resin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3 discs per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FORNEY INDUSTRIES INC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 71669\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FORNEY","offers":[{"title":"Default Title","offer_id":51558788268338,"sku":"71669","price":54.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3f0ef081d5f5e2428d9eee508de82cd.jpg?v=1786420566","url":"https:\/\/voomisupply.com\/products\/forney-industries-inc-71669-resin-fibre-disc-50-grit-4-5-in-3pk","provider":"Voomi Supply","version":"1.0","type":"link"}
