Built on the Cubitron II 775L platform, it uses 3M Precision Shaped Ceramic Grain — a triangular mineral structure that slices through material rather than plowing like conventional abrasive grains. At 320 grit and 5 inches in diameter, this disc delivers fast, consistent cut rates with significantly extended disc life compared to standard aluminum oxide or ceramic abrasives. The Stikit pressure-sensitive adhesive backing mounts and releases quickly on compatible backup pads, reducing changeover time during production finishing work.\u003c\/p\u003e\u003cp\u003eThis disc is suited for surface conditioning, blending, and fine stock removal on metals, composites, and painted surfaces in industrial, automotive body, and fabrication environments. The 320 grit rating makes it appropriate for intermediate-to-fine finishing passes where surface quality matters alongside cut rate. The film backing resists tearing at disc edges and conforms well to slightly contoured workpieces, making it a practical choice for production grinding and finishing operations where disc longevity directly affects labor costs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision Shaped Ceramic Grain slices substrate for faster, cleaner cuts\u003c\/li\u003e\n\u003cli\u003eCuts up to 2 times faster than conventional abrasive discs\u003c\/li\u003e\n\u003cli\u003eLasts up to 6 times longer than conventional abrasives, reducing disc changes\u003c\/li\u003e\n\u003cli\u003eFilm backing provides greater tear resistance and improved edge retention\u003c\/li\u003e\n\u003cli\u003eStikit PSA attachment system allows fast disc mounting and removal\u003c\/li\u003e\n\u003cli\u003eSuited for a wide variety of substrates with a primary focus on stock removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 5-inch Stikit-compatible backup pads and random orbital or right-angle sanders that accept PSA-mount discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounting is performed by pressing the PSA-backed disc firmly onto a clean, dry Stikit-compatible backup pad — ensure the pad surface is free of debris or adhesive residue before attachment. Power down the tool before mounting or removing any disc. Inspect the disc edge and backing for damage before each use and discard any disc showing tears, delamination, or glazing. Follow applicable shop safety protocols including eye and respiratory protection when grinding or finishing metal and composite materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 Type\u003c\/strong\u003e: Precision Shaped Ceramic Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Stikit Pressure-Sensitive Adhesive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 3.777 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 11.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 5.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 076308471069\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: 7100145470\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346276548914,"sku":"7100145470","price":356.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535840.jpg?v=1782076053","url":"https:\/\/voomisupply.com\/products\/3m-7100145470-abrasive-film-disc-320-grit-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
