Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film substrate, producing a consistent, repeatable surface finish pass after pass. This roll measures 3 inches wide by 50 feet long and carries a 15.0 micron grade, placing it in the mid-range of the available 0.10 to 30.0 micron grade spectrum. Technicians and machinists use this film where conventional abrasives cannot hold tolerance or maintain finish consistency on hard substrates such as ceramics, carbide, optical components, and hardened tool steels.\u003c\/p\u003e\u003cp\u003eThis lapping film is suited for precision grinding, polishing, and surface conditioning applications in industrial, optical, and toolroom environments. It is commonly used in fiber optic connector polishing, precision instrument component finishing, and die and mold work where surface geometry and finish repeatability are critical. The roll format is well suited to automated or semi-automated polishing fixtures and flat-lapping setups. Trades and technicians working with tight-tolerance components in calibration, optical, or toolroom contexts will find this format practical for high-volume or continuous-feed operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15.0 micron diamond abrasive grade for mid-range material removal and surface refinement\u003c\/li\u003e\n\u003cli\u003ePrecisely graded diamond particles ensure consistent, repeatable finish results\u003c\/li\u003e\n\u003cli\u003ePolyester film backing provides dimensional stability under load\u003c\/li\u003e\n\u003cli\u003eRoll format (3 inches x 50 ft) supports automated fixtures and extended-run lapping setups\u003c\/li\u003e\n\u003cli\u003eCompatible with extremely hard materials including ceramics, carbide, and hardened steel\u003c\/li\u003e\n\u003cli\u003ePart of a broader grade range from 0.10 to 30.0 micron for full finishing sequences\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on extremely hard materials such as ceramics, carbide, optical glass, and hardened metals.

Secure the film to a flat platen or lapping fixture appropriate for the workpiece geometry before use. Ensure the workpiece and fixture are free of contamination that could embed in the abrasive surface and compromise finish consistency. Follow the manufacturer guidance on backing plate hardness and lapping fluid compatibility for the specific substrate being processed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: 15.0 micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Range Available\u003c\/strong\u003e: 0.10 to 30.0 micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 ft\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: 2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111698433\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7100037872\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51342878212402,"sku":"7100037872","price":1230.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310527440.jpg?v=1782009356","url":"https:\/\/voomisupply.com\/products\/3m-7100037872-diamond-lapping-film-15-0-micron-roll","provider":"Voomi Supply","version":"1.0","type":"link"}
