Built on a high-strength polyester film backing with resin-bonded abrasive, this roll delivers fast-cutting action while maintaining dimensional consistency across the workpiece. The 30-micron grit rating positions it for intermediate to fine finishing passes on metal, plastic, and painted surfaces. At 2.5 inches wide and 300 feet long with a 1-inch core, this roll format suits both automated superfinishing equipment and manual lapping operations. Machinists, toolmakers, and automotive finishing technicians are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eThis microfinishing film roll is suited for applications requiring tight surface finish tolerances in metalworking, plastics finishing, paint spot repair, and automotive powertrain component finishing. Roll superfinishing operations on shafts, bearings, camshafts, and similar cylindrical components are common use cases. The polyester film backing provides consistent abrasive presentation, which is critical when achieving repeatable Ra values on precision components. It is used in both production shop environments and field repair scenarios where controlled material removal is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e30-micron abrasive rating for precise, close-tolerance finish work\u003c\/li\u003e\n  \u003cli\u003eHigh-strength polyester film backing for dimensional stability during use\u003c\/li\u003e\n  \u003cli\u003eResin-bonded abrasive construction for durability and consistent cut rate\u003c\/li\u003e\n  \u003cli\u003e2.5-inch width and 300-foot length supports extended production runs\u003c\/li\u003e\n  \u003cli\u003e1-inch core fits standard roll superfinishing and film-feed equipment\u003c\/li\u003e\n  \u003cli\u003eSuitable for metal, plastic, paint spot repair, and automotive powertrain components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on metal, plastic, paint, and automotive powertrain components requiring precise surface finishing; suitable for roll superfinishing equipment accepting a 1-inch core and 2.5-inch wide film stock.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of microfinishing film rolls should be performed by qualified machinists or finishing technicians familiar with the equipment in use. Ensure the machine is powered down and de-energized before loading or threading new film stock. Verify that the core diameter and film width are compatible with the equipment spindle and feed path before operation. Always follow the equipment manufacturer's guidelines for film tension, feed rate, and coolant application to avoid film tearing or inconsistent finish results.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit Rating\u003c\/strong\u003e: 30 Micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 300 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: High-strength polyester film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBonding Type\u003c\/strong\u003e: Resin-bonded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051141205212\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: 7100142401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347038634290,"sku":"7100142401","price":606.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310532527.jpg?v=1782097247","url":"https:\/\/voomisupply.com\/products\/3m-7100142401-microfinishing-film-roll-362l-30-micron","provider":"Voomi Supply","version":"1.0","type":"link"}
