Built on a heavyweight X-weight cloth backing, it runs dry and delivers consistent stock removal on metal, wood, and composite surfaces. The closed-coat construction packs aluminum oxide abrasive across the full belt surface, maintaining an active cutting face throughout the belt's service life. At 50 grit coarse grade, this belt is suited to rough shaping, weld blending, and surface preparation tasks where fast cutting action is the priority. Fabricators, metalworkers, and finishing trades reach for this belt when initial stock removal speed matters more than final surface finish.\u003c\/p\u003e\n\u003cp\u003eThis belt fits belt sanders and stationary or portable abrasive machines that accept a 3-1\/2 inch wide by 15-1\/2 inch long belt. The R228 series designation identifies the cloth-backed, closed-coat, aluminum oxide construction within the Norton lineup. It is a dry-use belt and is not rated for wet grinding or coolant-flooded operations. Typical applications include weld seam blending, pipe and structural steel prep, metal fabrication cleanup, and heavy wood stock removal in shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e50 grit coarse grade for aggressive stock removal and rapid material shaping\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive provides durable, consistent cutting on ferrous and non-ferrous metals and wood\u003c\/li\u003e\n  \u003cli\u003eClosed-coat construction maximizes abrasive coverage across the belt face for faster cutting\u003c\/li\u003e\n  \u003cli\u003eX-weight cloth backing resists tearing and flexing under load during demanding applications\u003c\/li\u003e\n  \u003cli\u003eDry-use rated belt suited to standard belt sander and power abrasive machine operation\u003c\/li\u003e\n  \u003cli\u003eNorton R228 series construction for reliable belt tracking and splice integrity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit belt sanders and abrasive machines that accept a 3-1\/2 inch wide by 15-1\/2 inch long abrasive belt in dry-use applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAbrasive belts are installed by trained trades, fabricators, or shop personnel familiar with belt sander equipment. Power down and disconnect the machine from its power source before changing belts. Confirm belt tracking direction matches the arrow marked on the belt backing before operating. Inspect the belt for tears or splice separation before each use and replace immediately if damage is found.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Width\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Length\u003c\/strong\u003e: 15-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoat Density\u003c\/strong\u003e: Closed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWet\/Dry Operation\u003c\/strong\u003e: Dry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R228\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191507\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: 78072721999\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540218413362,"sku":"78072721999","price":16.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e2bd395472763317ad99fd17e68d956.jpg?v=1785849228","url":"https:\/\/voomisupply.com\/products\/norton-78072721999-abrasive-belt-50-grit-3-1-2x15-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
