It features precisely graded diamond abrasive particles coated onto a polyester film substrate, delivering consistent, repeatable finishes across a wide range of micron grades from 0.10 to 30.0 micron. The pressure-sensitive adhesive backing allows for quick mounting to compatible backup pads or lapping fixtures. Machinists, tool and die technicians, and precision finishing specialists use this disc in applications where surface geometry and finish consistency are critical.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for flat surface lapping and light edge work on hard substrates including ceramics, carbide, glass, and hardened steel. The 668X series is the PSA-backed equivalent of the 661X film product and shares the same abrasive construction. Typical applications include precision optical component finishing, fiber optic connector polishing, and tight-tolerance metalworking operations where uniform material removal and low edge rounding are required. The disc format suits bench-mounted lapping machines and handheld finishing setups alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePSA backing for fast, secure mounting to lapping fixtures and backup pads\u003c\/li\u003e\n  \u003cli\u003ePrecisely graded diamond particles for consistent finish and repeatable results\u003c\/li\u003e\n  \u003cli\u003eAvailable in grades from 0.10 to 30.0 micron to suit multiple finishing stages\u003c\/li\u003e\n  \u003cli\u003eFlat surface geometry with low edge rounding for tight-tolerance work\u003c\/li\u003e\n  \u003cli\u003eLong abrasive life reduces disc change frequency and improves throughput\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing provides dimensional stability under load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a PSA-backed diamond lapping disc compatible with standard 2-inch backup pads and lapping fixtures used in precision surface finishing operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis disc is installed by pressing the PSA face firmly onto a clean, dry backup pad or flat lapping plate. Ensure the mounting surface is free of debris and oils before application to maintain full adhesive contact. No tools are required for mounting, but the backup pad must match the disc diameter for even abrasive contact. Discs should be stored flat and away from heat sources to preserve adhesive integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: PSA (Pressure-Sensitive Adhesive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilm Substrate\u003c\/strong\u003e: Polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMicron Grade Range\u003c\/strong\u003e: 0.10 to 30.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 668X\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: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111546895\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: 7100112797\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347474415922,"sku":"7100112797","price":244.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524246.jpg?v=1782106088","url":"https:\/\/voomisupply.com\/products\/3m-7100112797-diamond-lapping-film-disc-2-inch-psa","provider":"Voomi Supply","version":"1.0","type":"link"}
