The film uses precisely graded diamond abrasive particles coated onto a dimensionally stable polyester backing. At 9.0 micron grade, it produces a consistent, repeatable finish suitable for applications demanding tight surface tolerances. The roll format measures 8 inches wide by 50 feet long on a 3-inch core, making it compatible with standard lapping and polishing equipment. This product is used by technicians and tradespeople who require controlled material removal and fine finishing on hard substrates such as carbide, ceramic, glass, and hardened steel.\u003c\/p\u003e\n\u003cp\u003eThis lapping film is suited for precision finishing operations in tool and die, fiber optic connector polishing, semiconductor, and advanced manufacturing environments. The roll format allows the user to cut or dispense material as needed for flat lapping, cylindrical polishing, or hand-lapping fixtures. The 9.0 micron grade fits into a broader finishing sequence, typically used after coarser stock removal steps and before finer sub-micron finishing passes. It performs on substrates where conventional abrasive films would wear too quickly or fail to hold tolerance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecisely graded diamond particles deliver consistent cut rate and finish across the full roll\u003c\/li\u003e\n  \u003cli\u003e9.0 micron abrasive grade for controlled material removal on hard surfaces\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing provides dimensional stability under lapping pressure\u003c\/li\u003e\n  \u003cli\u003e8-inch width by 50-foot length on a 3-inch core fits standard dispensing equipment\u003c\/li\u003e\n  \u003cli\u003eAvailable grade range of 0.10 to 30.0 micron supports multi-step finishing sequences\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on extremely hard materials including carbide, ceramic, glass, and hardened metal surfaces where precise, repeatable surface finishing is required.

Ensure the workpiece and lapping surface are clean and free of contamination before use to avoid scratching from embedded particles. Use appropriate personal protective equipment when handling diamond abrasive media. Follow equipment manufacturer guidelines for roll tensioning and feed rate to maintain consistent finish results.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: 9.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Width\u003c\/strong\u003e: 8 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 Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 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: 00051111499641\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: 7000000304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345330635058,"sku":"7000000304","price":2945.33,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524060.jpg?v=1782054941","url":"https:\/\/voomisupply.com\/products\/3m-7000000304-diamond-lapping-film-9-0-micron-8x50ft-roll","provider":"Voomi Supply","version":"1.0","type":"link"}
