Based on the 661X product line, the 668X series uses precisely graded diamond particles coated onto a durable polyester film substrate. The pressure-sensitive adhesive backing allows for fast, secure mounting to compatible disc holders and backup pads. Available in grades ranging from 0.10 to 30.0 micron, this disc delivers a consistent, repeatable finish with flat surface geometry and minimal edge rounding. It is suited for applications where tight tolerances and controlled surface finishes are required across multiple passes.\u003c\/p\u003e\u003cp\u003eThis diamond lapping disc is used in precision grinding and finishing operations on hard materials such as ceramics, carbide, glass, and optical components. The PSA backing makes it compatible with standard disc-based lapping and polishing setups. It is commonly used in production environments where throughput and finish consistency are critical. The disc measures 8 inches in diameter and is sold individually, with a minimum order quantity of 25 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePSA backing for secure, fast mounting to disc holders and backup pads\u003c\/li\u003e\n\u003cli\u003ePrecisely graded diamond abrasive particles on a polyester film substrate\u003c\/li\u003e\n\u003cli\u003eDelivers flat surfaces with low edge rounding for tight-tolerance work\u003c\/li\u003e\n\u003cli\u003eConsistent, repeatable finish across multiple uses\u003c\/li\u003e\n\u003cli\u003eLong abrasive life reduces frequency of disc changes and improves throughput\u003c\/li\u003e\n\u003cli\u003eAvailable in grades from 0.10 to 30.0 micron for a wide range of finishing requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard disc-based lapping and polishing equipment that accepts 8-inch PSA-backed abrasive discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis disc is installed by pressing the PSA backing firmly onto a clean, dry backup pad or disc holder. Ensure the mounting surface is free of debris or residue before application to achieve full adhesion and prevent disc movement during use. Follow equipment manufacturer guidelines for disc speed and load pressure. Discs should be handled carefully to avoid contaminating the abrasive surface.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 8 inches\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\u003eAbrasive Type\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubstrate\u003c\/strong\u003e: Polyester film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Grade Range\u003c\/strong\u003e: 0.10 to 30.0 micron\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\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: 7000044731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345731977522,"sku":"7000044731","price":1135.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524337.jpg?v=1782062006","url":"https:\/\/voomisupply.com\/products\/3m-7000044731-diamond-lapping-film-disc-8-inch-psa","provider":"Voomi Supply","version":"1.0","type":"link"}
