Graded diamond particles are uniformly coated onto a dimensionally stable polyester film backing, delivering a consistent, repeatable finish pass after pass. Each sheet measures 6 inches x 6 inches and carries a 3.0 micron particle grade, making it suitable for fine lapping and polishing operations where tight surface tolerances are required. This product is the PSA-backed variant of the 661X series, allowing it to adhere directly to a flat backing plate or platen without additional fixturing.\u003c\/p\u003e\n\u003cp\u003eThis lapping film is used in precision finishing applications across optical, fiber optic connector, semiconductor, ceramic, and carbide tooling industries. The PSA backing simplifies sheet placement on flat lapping platens and is well suited for both production environments and bench-level finishing work performed by machinists, toolmakers, and precision technicians. The 3.0 micron grade falls within the mid-to-fine range of the available 0.10 to 30.0 micron product line, bridging rough stock removal and final polishing stages.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecisely graded 3.0 micron diamond abrasive particles for controlled, repeatable material removal\u003c\/li\u003e\n  \u003cli\u003ePSA backing adheres directly to flat lapping platens, eliminating the need for separate adhesive or fixturing\u003c\/li\u003e\n  \u003cli\u003ePolyester film substrate provides dimensional stability and resistance to tearing during use\u003c\/li\u003e\n  \u003cli\u003eConsistent particle distribution across the sheet surface for uniform finish results\u003c\/li\u003e\n  \u003cli\u003eSuitable for lapping and polishing extremely hard materials including ceramics, carbide, and optical glass\u003c\/li\u003e\n  \u003cli\u003ePart of a broad 0.10 to 30.0 micron grade range for multi-stage finishing sequences\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a PSA-backed replacement and complement to the 661X series diamond lapping film; compatible with flat lapping platens and backing plates used in standard precision finishing setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eApply the sheet to a clean, flat platen or backing plate, pressing firmly from the center outward to eliminate air bubbles before use. Ensure the work surface and platen are free of debris that could cause uneven contact or premature film damage. Replace sheets when abrasive performance drops noticeably or when surface contamination cannot be removed, as continued use of a degraded sheet will compromise finish consistency.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParticle Grade\u003c\/strong\u003e: 3.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSheet Size\u003c\/strong\u003e: 6 inches x 6 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\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: 00051111699577\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: 7010294661\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344678486322,"sku":"7010294661","price":345.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310527458.jpg?v=1782040078","url":"https:\/\/voomisupply.com\/products\/3m-7010294661-diamond-lapping-film-668x-psa-3-0-micron","provider":"Voomi Supply","version":"1.0","type":"link"}
