The disc features aluminum oxide mineral coated onto a 3 mil polyester film backing with a durable resin system and a pressure-sensitive adhesive (PSA) base for quick, secure mounting. Available in seven grades ranging from 0.05 to 60.0 micron, the 7000044817 delivers consistent cut rate, finish quality, and service life across repeated use cycles. At 8 inches in diameter, it is suited to benchtop lapping machines, superfinishing equipment, and fiber optic connector polishing fixtures. Licensed tradespeople and precision finishing technicians are the primary installers and users of this disc.\u003c\/p\u003e\n\u003cp\u003eThis disc is designed for demanding precision finishing work including fiber optic connector end-face polishing and roll superfinishing operations. The tight particle distribution ensures a repeatable surface finish from disc to disc, making it appropriate for both production-line environments and controlled service-bay applications. The harder resin system compared to the 261X series provides improved durability under sustained pressure. It is available in disc, sheet, and roll formats, giving technicians flexibility across different machine configurations and finishing setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide mineral on 3 mil polyester film for dimensional stability during finishing\u003c\/li\u003e\n  \u003cli\u003ePSA backing for fast, tool-free mounting to lapping plates and polishing fixtures\u003c\/li\u003e\n  \u003cli\u003eTight particle distribution delivers consistent finish and cut rate across the disc surface\u003c\/li\u003e\n  \u003cli\u003eHarder resin system than 261X series for extended service life under sustained load\u003c\/li\u003e\n  \u003cli\u003eAvailable in seven micron grades from 0.05 to 60.0 micron to cover rough through ultra-fine finishing stages\u003c\/li\u003e\n  \u003cli\u003eCommon applications include fiber optic finishing and roll superfinishing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on lapping machines, polishing fixtures, and superfinishing equipment that accept 8 inch diameter PSA-backed discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMount the disc onto a clean, flat lapping plate by aligning the PSA backing and pressing firmly to eliminate air pockets. Ensure the mating surface is free of debris and residual adhesive from previous discs before installation. No tools are required for mounting, but the plate should be stationary and the machine powered down during disc changeover. Follow equipment manufacturer guidelines and applicable shop safety procedures when operating lapping or superfinishing machinery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMineral\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: 3 mil polyester film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Pressure-Sensitive Adhesive (PSA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable Micron Grades\u003c\/strong\u003e: 0.05 to 60.0 micron (7 grades)\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\u003eUPC\u003c\/strong\u003e: 00051111497784\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: 7000044817\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347396854066,"sku":"7000044817","price":1412.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524022.jpg?v=1782103691","url":"https:\/\/voomisupply.com\/products\/3m-7000044817-aluminum-oxide-lapping-disc-8-in-psa","provider":"Voomi Supply","version":"1.0","type":"link"}
