Diamond mineral is bonded directly to a durable polyester film backing, delivering consistent cutting action and long service life under demanding conditions. At 74 micron grit and measuring 4 inches wide by 50 feet long on a 3-inch core, this roll is well suited for precision finishing operations where surface quality and dimensional control are critical. It is used by machinists, tool and die professionals, and surface finishing specialists working with materials that resist conventional abrasives.\u003c\/p\u003e\n\u003cp\u003eThis microfinishing film roll is designed for use on hard and difficult-to-finish materials such as thermal spray coatings, ceramics, carbides, chilled iron, and granite. It performs in automated roll-to-roll finishing equipment as well as hand-lapping and machine-guided applications. The polyester film backing maintains dimensional stability during use, which supports accurate, repeatable surface finishes across production runs. Industries including aerospace, tooling, hydraulics, and precision manufacturing commonly use this product type for achieving tight surface finish tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDiamond mineral abrasive bonded to polyester film backing for cutting performance on hard materials\u003c\/li\u003e\n  \u003cli\u003e74 micron grit rating suitable for superfinishing and fast finish reduction\u003c\/li\u003e\n  \u003cli\u003e4-inch width by 50-foot length on a 3-inch core for compatibility with roll-feed finishing equipment\u003c\/li\u003e\n  \u003cli\u003eEffective on thermal spray coatings, ceramics, carbides, chilled iron, granite, and similar hard substrates\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing provides dimensional stability for consistent, repeatable results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement roll for precision microfinishing equipment accepting 3-inch core, 4-inch wide film rolls used in superfinishing applications on hard materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and loading of microfinishing film rolls should be performed by qualified machinists or finishing technicians familiar with the host equipment. Power down and lock out the finishing machine before threading or replacing the film roll. Ensure the roll seats correctly on the 3-inch core arbor and tracks true before resuming operation to avoid edge damage or uneven wear. Follow all equipment manufacturer guidelines for feed rate and contact pressure appropriate to the material being finished.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 74 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 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Size\u003c\/strong\u003e: 3 inches\u003c\/li\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\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.38 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051141205731\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: 7000045314\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345137598770,"sku":"7000045314","price":12847.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310532550.jpg?v=1782050057","url":"https:\/\/voomisupply.com\/products\/3m-7000045314-diamond-microfinishing-film-roll-675l-74-micron","provider":"Voomi Supply","version":"1.0","type":"link"}
