This disc features a higher diamond concentration and a stronger resin bond compared to standard diamond lapping film, resulting in greater durability and a faster cut rate. Measuring 4.25 inches in diameter, it delivers a flat, consistent surface finish without rounding edges. Technicians and machinists working on tight-tolerance components rely on this disc for repeatable, high-quality results across multiple finishing stages.\u003c\/p\u003e\u003cp\u003eThis diamond lapping film disc is suited for precision lapping and polishing of optical components, fiber optic connectors, ceramic ferrules, hard metals, and other tight-tolerance surfaces. It is commonly used in industrial, manufacturing, and telecommunications maintenance environments where surface finish quality is critical. The 662XW series is available in multiple micron grades, including 0.50, 1.0, 1.50, 3.0, 6.0, and 9.0 micron, allowing users to select the appropriate grit progression for their finishing process.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigher diamond concentration for increased cut rate over standard diamond lapping film\u003c\/li\u003e\n\u003cli\u003eStronger resin bond provides added durability and extended abrasive life\u003c\/li\u003e\n\u003cli\u003eFlat surface contact minimizes rounding on precision components\u003c\/li\u003e\n\u003cli\u003eLong abrasive life reduces disc change frequency and increases throughput\u003c\/li\u003e\n\u003cli\u003eAvailable in discs, rolls, and sheets for flexible application setups\u003c\/li\u003e\n\u003cli\u003eMultiple micron grades available: 0.50, 1.0, 1.50, 3.0, 6.0, and 9.0 micron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard lapping fixtures and holders that accept 4.25-inch diameter lapping film discs in precision finishing and polishing operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis disc is installed and used by machinists, optical technicians, and fiber optic technicians performing precision surface finishing. Ensure the backing plate or lapping fixture is clean and free of debris before mounting the disc. Follow the manufacturer-recommended micron grade progression from coarse to fine for best surface finish results. Inspect the disc for wear regularly and replace when cut rate or surface finish quality declines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 662XW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable Micron Grades\u003c\/strong\u003e: 0.50, 1.0, 1.50, 3.0, 6.0, 9.0 micron\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: 00051111501481\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: 7000044872\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51348023836978,"sku":"7000044872","price":260.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524092.jpg?v=1782118400","url":"https:\/\/voomisupply.com\/products\/3m-7000044872-diamond-lapping-film-disc-4-25-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
