At 4-1\/2 inches in diameter with a 7\/8-inch arbor hole and a 50-grit abrasive surface, this disc is built for heavy stock removal and weld blending. The grain construction is paired with a resin fiber backing and a grinding aid that reduces heat buildup during use. Fabricators, welders, and metalworkers reach for this disc when working on steel, aluminum, and other non-ferrous metals where consistent cut rate and disc longevity both matter.\u003c\/p\u003e\u003cp\u003eThis disc is suited for use on angle grinders in fabrication shops, maintenance facilities, and production environments. It handles flat grinding, edge work, and surface prep on a range of metal substrates. The 50-grit rating makes it appropriate for initial material removal and weld grinding before finishing steps. It is sold in pack quantities, making it practical for ongoing shop use where disc turnover is regular.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e50-grit abrasive surface for aggressive stock removal and weld blending\u003c\/li\u003e\n\u003cli\u003e4-1\/2-inch diameter with 7\/8-inch arbor fits standard angle grinders\u003c\/li\u003e\n\u003cli\u003eResin fiber backing provides durability under sustained grinding pressure\u003c\/li\u003e\n\u003cli\u003eGrinding aid reduces heat and extends disc life on metal surfaces\u003c\/li\u003e\n\u003cli\u003eCompatible with steel, aluminum, and non-ferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement-style resin fiber disc for use with standard 4-1\/2-inch angle grinders accepting a 7\/8-inch arbor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of abrasive discs should be performed by qualified personnel following the angle grinder manufacturer's mounting instructions. Inspect the disc for damage before each use and never exceed the maximum RPM rating marked on the disc or tool. Wear appropriate PPE including eye protection and gloves during disc changes and grinding operations. Ensure the grinder is fully powered down and unplugged before mounting or removing the disc.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4-1\/2 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\u003eDisc Type\u003c\/strong\u003e: Resin Fiber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ARC ABRASIVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 37204\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARC ABRASIVES","offers":[{"title":"Default Title","offer_id":51343859286322,"sku":"37204","price":62.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310468089.jpg?v=1782025105","url":"https:\/\/voomisupply.com\/products\/arc-abrasives-37204-resin-fiber-disc-50-grit-4-1-2-x-7-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
