Aluminum oxide mineral is coated on a 3-mil polyester film backing using a durable resin system. The disc uses a pressure-sensitive adhesive (PSA) backing for fast mounting and removal. Available in seven abrasive grades ranging from 0.05 to 60.0 micron, it delivers consistent cut rate and finish across a wide range of surface finish requirements. The harder resin system compared to the 261X series contributes to longer disc life and more predictable performance.\u003c\/p\u003e\n\u003cp\u003eThis disc is designed for high-precision finishing work, most commonly fiber optic connector end-face finishing and roll superfinishing operations. The tight particle distribution of the aluminum oxide mineral helps maintain controlled surface finishes where consistency across a production run matters. It is well suited for use in manufacturing and service environments where repeatable results are required across multiple abrasive grades in sequence.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePSA backing for quick mounting and removal on compatible platens\u003c\/li\u003e\n  \u003cli\u003eTight particle size distribution for consistent surface finish results\u003c\/li\u003e\n  \u003cli\u003eHarder resin system than 261X for improved disc life\u003c\/li\u003e\n  \u003cli\u003eAvailable in seven grades from 0.05 to 60.0 micron\u003c\/li\u003e\n  \u003cli\u003eConsistent cut rate, finish quality, and disc life across grades\u003c\/li\u003e\n  \u003cli\u003eAlso available in sheets and rolls for alternate fixturing needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with PSA-compatible lapping and finishing platens in fiber optic polishing and roll superfinishing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMounting is performed by pressing the PSA-backed disc firmly onto a clean, flat platen surface, ensuring no air pockets are trapped beneath the disc. The platen and disc surface should be free of debris and oils before application to maintain full adhesive contact. Remove and replace the disc when cut rate or finish quality degrades. Follow the equipment manufacturer's procedures for disc removal and platen maintenance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 inches\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\u003eAbrasive Mineral\u003c\/strong\u003e: Aluminum oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: Pressure-sensitive adhesive (PSA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable Grades\u003c\/strong\u003e: 0.05 to 60.0 micron (7 grades)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 15.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 13.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 1.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: 7010309448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344458350898,"sku":"7010309448","price":1230.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534022.jpg?v=1782036400","url":"https:\/\/voomisupply.com\/products\/3m-7010309448-aluminum-oxide-psa-disc-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
