Built on a film polyester backing, this 320-grit ceramic disc delivers consistent material removal with the control needed for fine surface preparation. The ceramic abrasive grain is self-sharpening, maintaining cut rate over the life of the disc. At extra fine grade, it suits finish sanding passes where surface smoothness is the priority. Rated to 12,000 RPM, it handles sustained tool speeds without breaking down. The hook-and-loop attachment system allows fast disc changes without tools, reducing downtime during multi-step sanding operations.\u003c\/p\u003e\n\u003cp\u003eThis disc is designed for use with random orbital sanders in automotive bodywork, metal fabrication, woodworking, and composite finishing applications. The 320 extra fine grit makes it appropriate for final material prep before priming, sealing, or coating. The film polyester backing resists tearing and conforms slightly to contoured surfaces, making it suitable for both flat panels and mild curves. It is sold individually and is part of the 3M 775L series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-inch disc diameter with hook-and-loop backing for tool-free attachment and fast changes\u003c\/li\u003e\n  \u003cli\u003e320 grit ceramic abrasive for extra fine finishing and consistent cut rate\u003c\/li\u003e\n  \u003cli\u003eFilm polyester backing for durability and mild surface conformability\u003c\/li\u003e\n  \u003cli\u003eRated to 12,000 RPM for compatibility with standard random orbital sander speeds\u003c\/li\u003e\n  \u003cli\u003ePart of the 3M 775L series, purple disc color for easy grit identification\u003c\/li\u003e\n  \u003cli\u003eNo vacuum holes — suited for non-vac sanding applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with random orbital sanders accepting 5-inch hook-and-loop abrasive discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eConfirm the sander pad is clean and free of debris before attaching the disc to ensure full hook-and-loop engagement. Do not exceed the rated 12,000 RPM maximum speed. Inspect the disc for tears or loading before each use and replace if the abrasive surface is glazed or damaged. Proper eye protection and dust control measures should be used during all sanding operations.\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\u003eGrade\u003c\/strong\u003e: Extra Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\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: Film Polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Hook and Loop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 12,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Purple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 775L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 7100145405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51691269292338,"sku":"7100145405","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/951cdae0453a7f61b4ef70d07d97ffa6.jpg?v=1788282454","url":"https:\/\/voomisupply.com\/products\/3m-7100145405-hook-loop-disc-5-in-320-grit-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
