Diamond mineral is bonded to a durable polyester film backing, providing consistent cutting action and long service life across demanding applications. The roll measures 4 inches wide by 50 feet long with a 3-inch core, and the abrasive grade is 30 micron. This product is used by machinists, toolroom technicians, and precision grinding specialists who require repeatable surface finish results on hard substrates.\u003c\/p\u003e\n\u003cp\u003eThis microfinishing film roll is suited for superfinishing operations in precision manufacturing and industrial maintenance environments. It performs on hard materials including thermal spray coatings, ceramics, carbides, chilled iron, and granite. The 30 micron grade positions it for fast finish reduction where a consistent, controlled surface finish is required. It is commonly used on lapping fixtures, CNC superfinishing equipment, and manual film finishing setups in both production and toolroom settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDiamond mineral abrasive bonded to polyester film backing for durability and consistent cut\u003c\/li\u003e\n  \u003cli\u003e30 micron abrasive grade suited for fast finish reduction and superfinishing\u003c\/li\u003e\n  \u003cli\u003e4 inches wide by 50 feet long roll with 3-inch core for compatibility with standard film finishing equipment\u003c\/li\u003e\n  \u003cli\u003eEffective on hard materials including ceramics, carbides, thermal spray coatings, chilled iron, and granite\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing resists tearing and maintains dimensional stability during use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style abrasive film roll for use on standard film finishing and superfinishing equipment that accepts 4-inch wide rolls with a 3-inch core.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLoading and threading abrasive film rolls should be performed by qualified machinists or toolroom personnel familiar with the finishing equipment in use. Power down and lock out all rotating equipment before loading or changing the film roll. Follow equipment manufacturer guidelines for tension and feed rate settings. Inspect the film path for burrs or sharp edges that could cause premature film breakage before starting a finishing cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: 30 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Width\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Length\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 50051141205712\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: 7000044975\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347943948594,"sku":"7000044975","price":2203.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310532548.jpg?v=1782116471","url":"https:\/\/voomisupply.com\/products\/3m-7000044975-diamond-microfinishing-film-roll-30-micron","provider":"Voomi Supply","version":"1.0","type":"link"}
