Precisely graded diamond particles are coated onto a polyester film substrate, producing a consistent, repeatable finish across each use. The disc measures 4.125 inches in diameter and weighs 0.01 pounds. It is suited for applications requiring tight surface tolerances and sharp edge definition, making it a reliable choice for tool shops, optical component finishing, and precision manufacturing environments where surface quality is critical.\u003c\/p\u003e\u003cp\u003eThis diamond lapping film disc is used in precision lapping and finishing operations where hard substrates such as ceramics, carbides, glass, and hardened metals require controlled material removal. The polyester film backing provides dimensional stability during use. Sold individually, this disc fits into workflows that demand high repeatability and uniform surface texture across production runs or repair applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecisely graded diamond abrasive particles bonded to a polyester film backing\u003c\/li\u003e\n\u003cli\u003eProduces flat surfaces and sharp edges on extremely hard materials\u003c\/li\u003e\n\u003cli\u003eDelivers a consistent, repeatable finish across multiple uses\u003c\/li\u003e\n\u003cli\u003eFast cutting action supports increased throughput\u003c\/li\u003e\n\u003cli\u003eAvailable in multiple grades ranging from 0.10 to 30.0 micron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a precision lapping disc for use on extremely hard materials including ceramics, carbides, glass, and hardened metal surfaces where controlled, repeatable finishing is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of lapping film discs is typically performed by precision machinists or finishing technicians. Ensure the lapping plate or fixture surface is clean and free of debris before mounting the disc. Use appropriate backing plates and light, controlled pressure to avoid tearing the polyester film substrate. Follow all applicable shop safety procedures when working with abrasive materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.125 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\u003eAvailable Grit Range\u003c\/strong\u003e: 0.10 to 30.0 micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 7010307685\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344742514994,"sku":"7010307685","price":208.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524927.jpg?v=1782042298","url":"https:\/\/voomisupply.com\/products\/3m-7010307685-diamond-lapping-film-disc-4-125-in","provider":"Voomi Supply","version":"1.0","type":"link"}
