Precisely graded diamond abrasive particles are coated onto a stable polyester film substrate, producing a consistent, repeatable finish pass after pass. Each sheet measures 5.50 inches x 5.50 inches and carries a 0.50 micron abrasive grade, making it suited for ultra-fine finishing stages where surface roughness control is critical. This product is used by technicians and craftsmen working on fiber optic connectors, carbide tooling, ceramics, and other hard substrates that require controlled micro-finishing.\u003c\/p\u003e\u003cp\u003eThis lapping film is applied in applications where conventional abrasive media cannot achieve the required surface finish. Common use cases include polishing fiber optic ferrules, lapping precision optical components, finishing cutting tool edges, and final-stage surface preparation on hardened steel or ceramic parts. The 0.50 micron grade positions this sheet at the fine end of the finishing sequence, typically used after coarser micron grades have been applied. Both production environments and bench-level repair or fabrication settings use this format.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecisely graded 0.50 micron diamond abrasive particles for ultra-fine surface finishing\u003c\/li\u003e\n\u003cli\u003ePolyester film backing provides a stable, dimensionally consistent substrate\u003c\/li\u003e\n\u003cli\u003e5.50 inch x 5.50 inch sheet format fits standard lapping fixtures and hand-lapping setups\u003c\/li\u003e\n\u003cli\u003eDelivers repeatable finish results on extremely hard materials including carbide, ceramics, and hardened steel\u003c\/li\u003e\n\u003cli\u003ePart of a multi-grade system available 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 including carbide, ceramics, optical glass, and hardened metal surfaces requiring ultra-fine abrasive finishing.

Secure the sheet flat against a lapping plate or backing surface before use to prevent wrinkling or uneven abrasive contact. Follow the manufacturer sequence from coarser to finer micron grades to achieve the target surface finish efficiently. Clean the workpiece between grade changes to prevent coarser particles from contaminating the finer lapping stage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: 0.50 micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSheet Dimensions\u003c\/strong\u003e: 5.50 inches x 5.50 inches\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111699355\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: 7010307691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343143076146,"sku":"7010307691","price":287.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310527452.jpg?v=1782017974","url":"https:\/\/voomisupply.com\/products\/3m-7010307691-diamond-lapping-film-0-50-micron-sheet","provider":"Voomi Supply","version":"1.0","type":"link"}
