Precisely graded diamond abrasive particles are coated onto a polyester film backing, delivering a consistent, repeatable surface finish across every pass. The disc measures 8 inches in diameter and is suited for applications where tight surface geometry and edge sharpness are critical. This product is part of the most widely used diamond lapping film line in the industry, offering fast material removal with controlled, uniform results. Technicians and machinists working with ceramics, carbide, glass, or optical components rely on this disc for predictable, repeatable outcomes.\u003c\/p\u003e\u003cp\u003eThis disc is used in precision lapping and polishing operations across manufacturing, optical, electronics, and toolroom environments. It performs well on substrates that standard abrasives cannot effectively process, including hardened tool steel, technical ceramics, and fiber optic end faces. The polyester film backing provides dimensional stability during use, helping maintain flat surfaces and sharp edges throughout the lapping process. It is available as an individual disc and is also offered in sheet and roll formats to match various fixture and machine configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecisely graded diamond particles for consistent, repeatable finish results\u003c\/li\u003e\n\u003cli\u003ePolyester film backing provides dimensional stability and flatness\u003c\/li\u003e\n\u003cli\u003eFast cut rate increases throughput on hard-to-process materials\u003c\/li\u003e\n\u003cli\u003eProduces flatter surfaces and sharper edges compared to conventional abrasive films\u003c\/li\u003e\n\u003cli\u003eUniform finish across the full disc surface\u003c\/li\u003e\n\u003cli\u003eAvailable in multiple grades ranging from 0.10 to 30.0 micron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on extremely hard materials including ceramics, carbide, glass, and optical components where conventional abrasive films are insufficient.

Secure the disc to a flat lapping plate or appropriate fixture before use to ensure consistent contact pressure. Inspect the disc surface before each use and replace when abrasive loading or wear is evident. Do not exceed the recommended load or speed rating for the lapping equipment in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 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\u003eGrade Range\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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 7000008837\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345997594930,"sku":"7000008837","price":762.44,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310527476.jpg?v=1782068499","url":"https:\/\/voomisupply.com\/products\/3m-7000008837-diamond-lapping-film-disc-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
