Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film backing, producing a consistent cut rate and repeatable surface finish across the full length of the roll. The 6.0 micron grade makes this film well suited to intermediate lapping stages where controlled stock removal and fine surface refinement are both required. It is used by tool and die technicians, optical fabricators, and precision machinists.\u003c\/p\u003e\n\u003cp\u003eThis roll format measures 4 inches wide by 50 feet long on a 3-inch core, making it compatible with automated lapping machines, hand lapping fixtures, and spindle-driven film finishing systems. The 6.0 micron grade fits within the broader 3M Diamond Lapping Film range, which spans 0.10 to 30.0 micron, allowing a multi-stage finishing sequence using matched film grades. Typical applications include fiber optic connector polishing, precision bore finishing, and cutting tool reconditioning where surface geometry and finish must be held to tight tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecisely graded 6.0 micron diamond abrasive for controlled, repeatable stock removal\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing provides dimensional stability and resistance to tearing during use\u003c\/li\u003e\n  \u003cli\u003eRoll format (4 inches x 50 feet) supports both manual and machine lapping setups\u003c\/li\u003e\n  \u003cli\u003e3-inch core fits standard roll holders and automated film feed systems\u003c\/li\u003e\n  \u003cli\u003eEffective on extremely hard workpiece materials including ceramics, carbide, and hardened steel\u003c\/li\u003e\n  \u003cli\u003ePart of a graded series from 0.10 to 30.0 micron to support full multi-stage lapping sequences\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on lapping machines, polishing fixtures, and hand lapping setups that accept a 4-inch-wide roll on a 3-inch core.

Ensure the workpiece, fixture, and lapping plate are clean and free of debris before loading the film to prevent scratching or contamination of the finish surface. Use only the coolant or lubricant recommended for the specific workpiece material and lapping machine. Replace the film section when cut rate or finish quality degrades rather than attempting to restore a worn abrasive surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: 6.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Width\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Length\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111499573\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: 7000000302\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345784635698,"sku":"7000000302","price":1650.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524050.jpg?v=1782062871","url":"https:\/\/voomisupply.com\/products\/3m-7000000302-diamond-lapping-film-6-0-micron-4x50ft","provider":"Voomi Supply","version":"1.0","type":"link"}
