Diamond mineral is bonded to a durable polyester film backing, delivering consistent cutting action and long service life. Measuring 4 inches wide by 50 feet long with a 3-inch core, this roll is sized for production and shop use. The 20-micron grade targets precise surface finish requirements on materials that conventional abrasives struggle to cut effectively. Machinists, tool-and-die shops, and surface finishing specialists rely on this product for controlled, repeatable results.\u003c\/p\u003e\n\u003cp\u003eThis microfinishing film roll is used in superfinishing operations on thermal spray coatings, ceramics, carbides, chilled iron, and granite. It is suited for applications where tight surface finish tolerances are required and conventional abrasive films or stones fall short. Typical scenarios include precision grinding and lapping operations in industrial, aerospace, and tooling environments where hard substrate finishing demands a consistent diamond abrasive medium.\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 rate\u003c\/li\u003e\n  \u003cli\u003e20-micron grade for superfinishing and rapid finish reduction on hard materials\u003c\/li\u003e\n  \u003cli\u003e4 inches x 50 ft roll format with 3-inch core suits production and bench shop setups\u003c\/li\u003e\n  \u003cli\u003eEffective on thermal spray coatings, ceramics, carbides, 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 for use on hard materials including thermal spray coatings, ceramics, carbides, chilled iron, and granite where superfinishing or fast finish reduction is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis product is installed and used by machinists, surface finishing technicians, and tool-and-die professionals. Ensure the workpiece is securely fixtured and the finishing equipment is powered down before loading or changing the abrasive film. Use appropriate personal protective equipment, including eye protection and gloves, when handling diamond abrasive media. Follow equipment manufacturer guidelines for film tension and feed rate to avoid tearing or uneven wear.\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\u003eGrade\u003c\/strong\u003e: 20 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 ft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\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: 00051141205700\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: 7000044974\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51348059717938,"sku":"7000044974","price":1667.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310532537.jpg?v=1782119486","url":"https:\/\/voomisupply.com\/products\/3m-7000044974-diamond-microfinishing-film-roll-20-micron","provider":"Voomi Supply","version":"1.0","type":"link"}
