Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film backing, delivering a consistent and repeatable finish from one use to the next. At 15.0 microns, this grade is suited for intermediate stock removal and surface refinement on materials such as ceramics, carbide, hardened steel, optical components, and fiber optic ferrules. The roll format measures 1 inch wide by 50 feet long on a 3-inch core, making it adaptable to automated lapping equipment and manual fixtures alike.\u003c\/p\u003e\n\u003cp\u003eThis lapping film is used in applications where tight surface finish tolerances are required. Typical environments include precision tool and die shops, optical fabrication, fiber optic termination and polishing, electronics manufacturing, and hard-materials finishing operations. The 15.0 micron grade fits into a broader lapping sequence, generally used after coarser stock removal and before finer finishing grades. Technicians and machinists working with lapping fixtures, rotary tools, or flat-bed lapping machines will find the roll format practical for cutting custom lengths to suit the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e15.0 micron diamond abrasive grade for intermediate precision lapping and surface refinement\u003c\/li\u003e\n  \u003cli\u003ePrecisely graded diamond particles provide consistent, repeatable surface finishes\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing offers dimensional stability during lapping operations\u003c\/li\u003e\n  \u003cli\u003eRoll format (1 inch x 50 feet) allows custom length cutting for varied fixture types\u003c\/li\u003e\n  \u003cli\u003eCompatible with wet or dry lapping processes on ceramics, carbide, hardened steel, and optical substrates\u003c\/li\u003e\n  \u003cli\u003ePart of a broader grade range spanning 0.10 to 30.0 micron for full lapping sequences\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on extremely hard materials including ceramics, carbide, hardened steel, and optical components.

Ensure lapping fixtures and backing plates are clean and free of debris before mounting film to avoid surface contamination or uneven abrasion. Film should be secured flat against the lapping surface with no wrinkles or overlaps. Follow the equipment manufacturer guidelines and applicable shop safety protocols when operating rotary or flat-bed lapping machinery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: 15.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\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\u003eRoll Width\u003c\/strong\u003e: 1 inch\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\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111698150\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: 7100029972\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346083217714,"sku":"7100029972","price":414.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310527481.jpg?v=1782070901","url":"https:\/\/voomisupply.com\/products\/3m-7100029972-diamond-lapping-film-15-0-micron-roll","provider":"Voomi Supply","version":"1.0","type":"link"}
