Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film backing, producing a consistent, repeatable finish with every pass. This sheet measures 9 inches x 11 inches and carries a 9.0 micron grade, placing it in the mid-range of the available 0.10 to 30.0 micron product line. It is used by toolmakers, optical technicians, and precision machinists who require tight control over surface finish quality across ceramic, carbide, hardened steel, and similar substrates.\u003c\/p\u003e\u003cp\u003eThis lapping film is suited for bench lapping, hand lapping, and fixture-based finishing operations in tool and die shops, optical fabrication, fiber optic connector polishing, and precision instrument manufacturing. The polyester film backing allows the sheet to conform to flat lapping plates and backing pads without stretching or tearing during use. The 9.0 micron grade is commonly used as an intermediate or final finishing step when working down from coarser stock removal grits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9.0 micron precisely graded diamond abrasive for controlled material removal\u003c\/li\u003e\n\u003cli\u003ePolyester film backing provides dimensional stability and resistance to tearing\u003c\/li\u003e\n\u003cli\u003eConsistent particle distribution delivers repeatable surface finish results\u003c\/li\u003e\n\u003cli\u003eCompatible with wet or dry lapping techniques on hard substrates\u003c\/li\u003e\n\u003cli\u003eStandard 9 inches x 11 inches sheet format fits common lapping fixtures and backing plates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on extremely hard materials including carbide, ceramic, hardened steel, and optical glass where conventional abrasives are ineffective.

Secure the sheet to a flat lapping plate or appropriate backing pad before use to prevent slippage. Ensure the workpiece and lapping surface are clean and free of contamination from coarser abrasive grades before switching to this film. Follow the manufacturer and shop safety guidelines for abrasive finishing operations, including appropriate eye and hand protection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: 9.0 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\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: 7000044854\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343293972786,"sku":"7000044854","price":503.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524081.jpg?v=1782019877","url":"https:\/\/voomisupply.com\/products\/3m-7000044854-diamond-lapping-film-9-0-micron-sheet","provider":"Voomi Supply","version":"1.0","type":"link"}
