Precisely graded diamond particles are coated onto a polyester film backing, producing a consistent and repeatable finish across applications where standard abrasives cannot achieve the required surface quality. At 8 inches in diameter, this disc suits bench lapping and machine lapping setups. It is available in grades ranging from 0.10 to 30.0 micron, making it adaptable across rough stock removal and fine finishing stages.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in precision grinding and lapping operations where tight surface tolerances and sharp, flat edges are required. Common applications include finishing ceramics, carbide, optical components, fiber optic connectors, and other hard substrates. It is suited for production environments where throughput and finish consistency must be maintained across multiple workpieces. Technicians and machinists working with hard-to-finish materials select this film for its fast cut rate and uniform output.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecisely graded diamond particles coated on polyester film for repeatable, uniform finish\u003c\/li\u003e\n  \u003cli\u003eFast cut rate increases throughput on hard materials\u003c\/li\u003e\n  \u003cli\u003eProduces flatter surfaces and sharper edges compared to conventional abrasives\u003c\/li\u003e\n  \u003cli\u003eAvailable in multiple grades from 0.10 to 30.0 micron\u003c\/li\u003e\n  \u003cli\u003eAlso available in sheet and roll formats for different equipment configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on bench lapping machines and rotary lapping equipment that accept 8-inch diameter discs.

Secure the disc to the platen per equipment manufacturer instructions before beginning any lapping operation. Inspect the disc for tears or uneven coating before each use. Do not exceed the speed rating of the lapping machine or apply excessive downward pressure, as this can cause uneven wear of the diamond coating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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: 00051138719203\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: 7000008839\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343873409330,"sku":"7000008839","price":762.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524291.jpg?v=1782025236","url":"https:\/\/voomisupply.com\/products\/3m-7000008839-diamond-lapping-film-disc-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
