Built on a heavy YF-weight polyester cloth backing with closed coat construction, this belt delivers aggressive cutting action and a fine, consistent finish. The silicon carbide mineral paired with cork particles works together to remove material efficiently while refining the surface to a fine finish. Resin bonding helps the abrasive withstand heat buildup during use, extending belt life in demanding applications. At 48 inches long and 4 inches wide with a 320 grit rating, this belt is suited for finishing work where surface quality matters.\u003c\/p\u003e\u003cp\u003eThis belt is used in metal fabrication and finishing environments where a controlled, fine surface finish is required. It is particularly well suited for producing the characteristic blue finish on stainless steel, a common specification in food service equipment, architectural metalwork, and industrial fabrication. The flexible polyester cloth backing allows the belt to conform to contoured and irregular surfaces, making it useful for parts that are not perfectly flat. It is typically installed and operated by metal finishing technicians and fabricators working with stationary or portable belt grinders and sanders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eYF-weight polyester cloth backing provides durability and flexibility for contoured surface work\u003c\/li\u003e\n\u003cli\u003eSilicon carbide abrasive and cork particles deliver aggressive cut with fine finishing capability\u003c\/li\u003e\n\u003cli\u003eClosed coat construction increases grain density for consistent finish on hard metal surfaces\u003c\/li\u003e\n\u003cli\u003eResin bond system resists heat deterioration to extend belt service life\u003c\/li\u003e\n\u003cli\u003eWaterproof polyester material allows easy debris and swarf removal during use\u003c\/li\u003e\n\u003cli\u003e320 grit rating suited for final finishing and cosmetic polishing stages\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on belt sanders and grinders accepting a 48 inch by 4 inch abrasive belt.

Always power down and lock out the sanding machine before installing or replacing the belt. Confirm belt tracking and tension per the equipment manufacturer guidelines before resuming operation. Inspect the belt for tears or damage prior to each use and do not exceed the maximum operating speed rated for the belt and machine combination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 320\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Length\u003c\/strong\u003e: 48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Width\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Silicon Carbide with Cork Particles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: YF-Weight Polyester Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoat Type\u003c\/strong\u003e: Closed Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100025550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346857886002,"sku":"7100025550","price":2415.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310528344.jpg?v=1782092579","url":"https:\/\/voomisupply.com\/products\/3m-7100025550-sanding-belt-320-grit-48x4-inch-silicon-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
