It consists of precisely graded diamond abrasive particles coated onto a dimensionally stable polyester film backing. At 0.10 micron grit, this sheet is engineered for ultra-fine finishing and polishing operations where surface consistency and repeatability are critical. Each sheet measures 9 inches x 11 inches and is sold in a minimum quantity of 10 sheets. This product is used by machinists, optical technicians, fiber optic technicians, and precision tooling professionals who require controlled, repeatable surface finishes.\u003c\/p\u003e\n\u003cp\u003eThis lapping film is suited for finishing operations on carbide, ceramic, hardened steel, optical components, fiber optic connectors, and other hard or brittle substrates. The 0.10 micron grade places it at the finest end of the available range, making it appropriate for final-stage polishing rather than stock removal. It is commonly used in applications where surface roughness tolerances are measured at the sub-micron level, including fiber optic end-face preparation and precision optical grinding.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.10 micron diamond particle grade for ultra-fine surface finishing\u003c\/li\u003e\n  \u003cli\u003ePrecisely graded diamond abrasive ensures consistent, repeatable results across multiple passes\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing provides dimensional stability during use\u003c\/li\u003e\n  \u003cli\u003e9 inches x 11 inches sheet size fits standard lapping fixtures and flat platens\u003c\/li\u003e\n  \u003cli\u003eSuitable for extremely hard materials including carbide, ceramic, and optical substrates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision lapping sheet for use on flat or semi-flat lapping surfaces with extremely hard workpiece materials.

Ensure the backing surface is clean and flat before placing the sheet to avoid uneven abrasion or film buckling. The film can be used wet or dry depending on the application requirements. Inspect the film for wear after each use and replace when particle loading or surface breakdown is evident.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit Grade\u003c\/strong\u003e: 0.10 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSheet Size\u003c\/strong\u003e: 9 inches x 11 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: 0.02 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: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111501429\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: 7000044869\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345759600946,"sku":"7000044869","price":503.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524090.jpg?v=1782062342","url":"https:\/\/voomisupply.com\/products\/3m-7000044869-diamond-lapping-film-0-10-micron-sheet","provider":"Voomi Supply","version":"1.0","type":"link"}
