Built on a dimensionally stable polyester film base, it uses precisely graded diamond abrasive particles to deliver a consistent, repeatable surface finish. This sheet is graded at 15.0 micron, making it suitable for intermediate lapping and polishing stages where tight surface finish control is required. At 3 inches x 8 inches, the sheet format is well-suited for bench lapping fixtures, flat laps, and hand-held backing plates. The PSA backing allows the film to mount directly to a flat substrate without additional adhesive. Technicians and precision tooling professionals use this film when working on fiber optic connectors, carbide tooling, ceramics, and other hard substrates.\u003c\/p\u003e\n\u003cp\u003eThis lapping film is used in applications requiring controlled, step-by-step material removal on hard surfaces. Typical environments include precision optical finishing, fiber optic termination and polishing, carbide and ceramic component preparation, and fine tooling work. The 15.0 micron grade fits into a broader progression sequence, as the 668X line is available across a wide range from 0.10 to 30.0 micron. It is sold individually (each) with a minimum order quantity of 25 sheets, making it appropriate for shop-level or production-level use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e15.0 micron precisely graded diamond abrasive for consistent, repeatable finish results\u003c\/li\u003e\n  \u003cli\u003ePSA backing mounts directly to flat lapping plates or backing substrates without separate adhesive\u003c\/li\u003e\n  \u003cli\u003ePolyester film base provides dimensional stability during use\u003c\/li\u003e\n  \u003cli\u003eEffective on extremely hard materials including carbide, ceramics, and optical components\u003c\/li\u003e\n  \u003cli\u003ePart of the 668X series, available in grades from 0.10 to 30.0 micron for full progression sequences\u003c\/li\u003e\n  \u003cli\u003eSheet format (3 inches x 8 inches) suits bench lapping and hand-held fixture use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a PSA-backed alternative to the 661X diamond lapping film series, suited for use with standard flat lapping plates and backing fixtures that accept PSA-mount abrasive sheets in a 3 inches x 8 inches format.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eClean and dry the lapping plate or backing substrate thoroughly before applying the PSA sheet to ensure full adhesion and prevent film movement during use. Apply firm, even pressure across the sheet surface when mounting to eliminate air pockets. For multi-step finishing sequences, progress through micron grades in order to avoid cross-contamination of abrasive particles between grades. Dispose of worn sheets before surface finish inconsistency develops, as degraded diamond abrasive will produce uneven results on precision surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: 15.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: Polyester film with PSA\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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade Range Available\u003c\/strong\u003e: 0.10 to 30.0 micron\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: 00051111560303\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: 7010325375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345386504498,"sku":"7010325375","price":324.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524334.jpg?v=1782056668","url":"https:\/\/voomisupply.com\/products\/3m-7010325375-diamond-lapping-film-668x-15-0-micron-psa","provider":"Voomi Supply","version":"1.0","type":"link"}
