Built on the 668X platform, it uses precisely graded diamond particles coated onto a dimensionally stable polyester film substrate. The pressure-sensitive adhesive backing allows fast, tool-free mounting to disc platens. Designed for flat, consistent material removal, this disc delivers a uniform, repeatable finish across production and repair applications where surface geometry and edge integrity are critical. Technicians working with ceramics, carbides, optical components, and similar hard substrates rely on this disc for controlled, measurable results.\u003c\/p\u003e\u003cp\u003eThis diamond lapping film disc is suited for precision grinding and finishing operations in industrial, optical, and tooling environments. It is used on rotary lapping machines and flat platen systems where consistent stock removal and low edge rounding are required. The disc format is appropriate for benchtop finishing stations and production-line lapping setups. Grades ranging from 0.10 to 30.0 micron cover roughing through final-polish stages on materials that defeat conventional abrasives.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePSA backing for fast, tool-free mounting to disc platens\u003c\/li\u003e\n\u003cli\u003ePrecisely graded diamond abrasive particles for repeatable, uniform finish\u003c\/li\u003e\n\u003cli\u003eFlat surface removal with low edge rounding for geometry-critical parts\u003c\/li\u003e\n\u003cli\u003eFast cut rate increases throughput and reduces cycle time\u003c\/li\u003e\n\u003cli\u003eLong abrasive life reduces disc change frequency in production settings\u003c\/li\u003e\n\u003cli\u003eAvailable across a wide micron range from 0.10 to 30.0 micron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on rotary and flat platen lapping machines that accept 12-inch PSA-backed abrasive discs.

Ensure the platen is stationary before pressing the disc into place to prevent misalignment. Follow equipment manufacturer guidelines for platen speed and applied pressure appropriate to the workpiece material and selected micron grade. Inspect the disc for loading or wear and replace when cut rate or finish quality degrades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: PSA (pressure-sensitive adhesive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicron Grade Range\u003c\/strong\u003e: 0.10 to 30.0 micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.06 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: 10\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: 7100103089\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343091499314,"sku":"7100103089","price":815.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524339.jpg?v=1782016343","url":"https:\/\/voomisupply.com\/products\/3m-7100103089-diamond-lapping-film-disc-12-inch-psa","provider":"Voomi Supply","version":"1.0","type":"link"}
