Built on a C-weight paper backing with a ceramic aluminum oxide abrasive coating, this disc delivers consistent cutting action at 320 grit. The hook and loop attachment system allows for quick disc changes without adhesive residue or downtime. Each package contains 50 discs, making it a practical stock item for shops running high daily throughput on sanding and blending operations.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in collision repair, commercial and specialty vehicle refinishing, and marine surface preparation applications. The 320 grit rating places it in the fine-finishing range, suited for final sanding passes before primer or topcoat application. The blue ceramic aluminum oxide abrasive maintains a sharp cutting edge longer than conventional aluminum oxide, reducing disc consumption on production-volume jobs. The paper backing provides a flexible yet controlled cut on both flat and contoured panels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e320 grit ceramic aluminum oxide abrasive for fine surface finishing\u003c\/li\u003e\n  \u003cli\u003e5-inch diameter with hook and loop backing for fast, tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003eC-weight paper backing balances flexibility and support on contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eCoated abrasive construction for consistent material removal and cut rate\u003c\/li\u003e\n  \u003cli\u003e50 discs per package suitable for production-volume sanding operations\u003c\/li\u003e\n  \u003cli\u003eRated for collision repair, marine, and commercial vehicle applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in collision repair, commercial and specialty vehicle, and marine applications.

Ensure the pad and disc diameters match before use to avoid uneven wear or edge lifting. Inspect the disc for tears or loading before each use and replace as needed. Disc mounting and sanding operations do not require specialized tools but should follow standard shop safety practices including eye and respiratory protection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 320\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Paper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 321U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.56 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191506\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100215945\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51541759131954,"sku":"7100215945","price":77.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f465d58037c33177c253d6f4740cb165.jpg?v=1785884206","url":"https:\/\/voomisupply.com\/products\/3m-7100215945-hook-loop-disc-320-grit-5-inch-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
