Part of the 668X series, it uses precisely graded diamond abrasive particles coated onto a dimensionally stable polyester film backing. The pressure-sensitive adhesive backing allows for fast, secure mounting on compatible backing plates or platens. This disc is suited for applications where consistent, repeatable surface finishes are required at tight tolerances. Licensed technicians and precision machinists working with hard substrates rely on this product for controlled material removal and uniform surface refinement.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in lapping and polishing operations across industries that demand fine surface finishes on hard materials such as ceramics, carbide, glass, and optical components. It performs in both automated and manual lapping setups. The 668X series represents the PSA-backed counterpart to the 661X product line, offering the same abrasive performance with the added convenience of adhesive mounting. Available grades in the 668X range span from 0.10 to 30.0 micron, covering rough stock removal through final polishing stages.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePSA backing for secure, tool-free mounting on backing plates\u003c\/li\u003e\n  \u003cli\u003ePrecisely graded diamond particles deliver consistent, repeatable finishes\u003c\/li\u003e\n  \u003cli\u003eFast cut rate increases throughput in production lapping operations\u003c\/li\u003e\n  \u003cli\u003eProduces flat surfaces with low edge rounding\u003c\/li\u003e\n  \u003cli\u003eUniform finish across the full disc surface\u003c\/li\u003e\n  \u003cli\u003eExtended abrasive life reduces disc change frequency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on compatible PSA lapping platens and backing plates that accept 4-inch diameter discs.

Before mounting, ensure the platen or backing plate surface is clean and free of debris or residual adhesive from previous discs. Peel the liner and press the PSA disc firmly and evenly onto the platen to prevent air pockets. Do not reuse a disc once removed, as the PSA bond degrades on reapplication.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4 inches\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\u003eAbrasive Type\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilm Backing Material\u003c\/strong\u003e: Polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable Grades\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\u003ePackage Weight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 7.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 4.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111546987\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: 7010359522\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344715940146,"sku":"7010359522","price":492.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524258.jpg?v=1782041375","url":"https:\/\/voomisupply.com\/products\/3m-7010359522-diamond-lapping-film-disc-4-inch-psa","provider":"Voomi Supply","version":"1.0","type":"link"}
