Built on a heavyweight X-weight cloth backing with closed-coat aluminum oxide abrasive, it delivers consistent cut rate and finish quality across ferrous metals, non-ferrous metals, and hardwoods. At 180 grit, it falls in the very fine range, making it suitable for final stock removal, blending welds, and preparing surfaces ahead of finishing. The R228 series construction keeps the abrasive layer dense and uniform, which helps maintain an even scratch pattern throughout the belt's service life.\u003c\/p\u003e\n\u003cp\u003eThis belt is sized at 3 inches wide by 21 inches long, fitting compact portable belt sanders commonly used in metal fabrication shops, pipefitting, HVAC duct work, and general maintenance environments. The 180-grit, very fine grade targets finish passes rather than aggressive stock removal. Dry operation only — no coolant or water. Trade professionals in metal fab, plumbing rough-in finishing, and light industrial maintenance will find this belt appropriate for deburring pipe ends, smoothing weld seams, and prepping surfaces for coatings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e180 grit, very fine grade for finish-pass surface preparation and blending\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive mineral — durable cutting performance on metal and wood\u003c\/li\u003e\n  \u003cli\u003eClosed-coat construction for dense, uniform abrasive coverage and consistent scratch pattern\u003c\/li\u003e\n  \u003cli\u003eX-weight cloth backing provides flexibility and tensile strength for portable belt sander use\u003c\/li\u003e\n  \u003cli\u003eDry-use only — no wet or coolant operation\u003c\/li\u003e\n  \u003cli\u003eR228 series designation for consistent OEM-style replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit portable and stationary belt sanders that accept a 3-inch by 21-inch abrasive belt.

Power down and unplug the sander before changing belts. Ensure the belt seats fully on both the drive roller and idler before tensioning. Inspect the platen and rollers for debris or wear that could cause uneven belt tracking or premature failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Width\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Length\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 180\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\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: 0.3 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: 78072776779\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539623641394,"sku":"78072776779","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09999fe3c2b056a4706e77da0d4f3ac7.jpg?v=1785843695","url":"https:\/\/voomisupply.com\/products\/norton-78072776779-abrasive-belt-180-grit-3x21-in-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
