3M 7100019802 Diamond Lapping Film 662XW 1.0 Micron

Product Description

The 3M 7100019802 is a single sheet of 3M Diamond Lapping Film 662XW, sized 9 inches x 11 inches and graded at 1.0 micron. It is engineered for precision surface finishing and fine material removal on tight-tolerance components. A higher diamond concentration combined with a stronger resin bond delivers increased durability and a faster cut rate compared to standard diamond lapping film. The polyester film backing provides dimensional stability during use. This product is sold individually and is suited for use by machinists, optical technicians, toolmakers, and other precision-trade professionals who require consistent, repeatable surface finish results.

Diamond lapping film in the 1.0 micron grade is typically used in the final stages of precision lapping and polishing workflows. Common applications include finishing optical fiber connectors, lapping precision metal components, polishing carbide and ceramic surfaces, and refining cutting tool edges. The 9 inches x 11 inches sheet format is compatible with hand lapping, flat lapping plates, and fixture-based lapping setups. It is appropriate for both production environments and field service applications where surface finish quality is critical.

Compatibility

Designed for use in precision lapping and polishing applications requiring a 1.0 micron diamond abrasive film in a 9 inches x 11 inches sheet format.

Installation Notes

Lapping film should be placed abrasive-side up on a clean, flat lapping plate or backing surface before use. Ensure the work surface and film are free of debris that could cause scratching or uneven material removal. Use appropriate personal protective equipment, including eye protection, when handling abrasive materials. Follow the workpiece manufacturer's specifications for acceptable surface finish tolerances before beginning any lapping operation.
