The disc is constructed from a polyester film base coated with precisely graded diamond abrasive particles. This construction delivers a consistent, repeatable finish across applications where surface geometry and edge sharpness are critical. It is used by machinists, tool and die technicians, fiber optic polishing technicians, and other trades that require controlled material removal on hard substrates. The diamond abrasive is available across multiple grades ranging from 0.10 to 30.0 micron.\u003c\/p\u003e\n\u003cp\u003eThis lapping film disc fits into precision finishing workflows for carbide tooling, ceramics, glass, optical components, and fiber optic connectors. The 4-inch disc format is suited for use on lapping plates, polishing fixtures, and backing pads in both bench and production environments. Its polyester film base maintains dimensional stability under light to moderate pressure, making it appropriate for applications that require flat surfaces and sharp, burr-free edges.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecisely graded diamond particles for controlled, repeatable material removal\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing maintains flatness and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eFast cut rate supports higher throughput in production finishing\u003c\/li\u003e\n  \u003cli\u003eProduces flat surfaces and sharp edges on hard materials\u003c\/li\u003e\n  \u003cli\u003eAvailable in grades from 0.10 to 30.0 micron for coarse through fine finishing\u003c\/li\u003e\n  \u003cli\u003eDisc format compatible with standard lapping plates and backing fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on extremely hard materials including carbide, ceramics, glass, and optical substrates.

Ensure the work surface and fixture are free of contamination that could cause inconsistent contact or scratching. Apply only light, consistent pressure during lapping to preserve the abrasive coating and maintain surface geometry. Handling and use should follow the manufacturer's guidelines for the specific micron grade selected.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4 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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 7.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 4.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111697177\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: 7100135201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347785220402,"sku":"7100135201","price":401.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524919.jpg?v=1782113718","url":"https:\/\/voomisupply.com\/products\/3m-7100135201-diamond-lapping-film-disc-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
