Part of the 668X series, it features precisely graded diamond particles coated on a durable polyester film backing. At a 30.0 micron grade, this sheet delivers a consistent, repeatable surface finish suited for tight-tolerance lapping and polishing operations. Each sheet measures 3 inches x 8 inches and is sold individually. It is the PSA-backed counterpart to the 661X product line, allowing secure mounting to flat or backing-plate surfaces without additional adhesive.\u003c\/p\u003e\n\u003cp\u003eThis lapping film is used in precision machining, tooling, and finishing applications where surface geometry and finish consistency are critical. It is well suited for lapping optical components, ceramic surfaces, carbide tooling, and other hard substrates. The PSA backing makes it practical for use on flat lapping fixtures and hand-held backing pads. Technicians and machinists working in tight-tolerance environments rely on this film for final-stage material removal and surface conditioning.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecisely graded diamond abrasive particles for consistent, repeatable finish quality\u003c\/li\u003e\n  \u003cli\u003e30.0 micron grade suitable for intermediate to fine lapping of hard materials\u003c\/li\u003e\n  \u003cli\u003ePSA backing allows direct adhesive mounting to flat lapping plates or backing pads\u003c\/li\u003e\n  \u003cli\u003ePolyester film substrate provides dimensional stability during use\u003c\/li\u003e\n  \u003cli\u003e3 inches x 8 inches sheet format for versatile fixture compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and equivalent to the 3M 661X diamond lapping film in PSA-backed format.

Before applying, ensure the lapping plate or backing surface is clean, dry, and free of debris that could cause uneven adhesion or film distortion. Peel the PSA liner and apply the film smoothly to avoid air bubbles. Do not reuse the sheet once removed, as the PSA bond and abrasive surface may be compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 30.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSheet Size\u003c\/strong\u003e: 3 inches x 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: Pressure-Sensitive Adhesive (PSA) polyester film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Diamond\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  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111560310\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: 7010298834\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344730554674,"sku":"7010298834","price":436.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524335.jpg?v=1782041888","url":"https:\/\/voomisupply.com\/products\/3m-7010298834-diamond-lapping-film-668x-30-0-micron-psa","provider":"Voomi Supply","version":"1.0","type":"link"}
