3M 7010325480 Diamond Lapping Film 661X 0.10 Micron Sheet

Product Description

The 3M 7010325480 is a precision diamond lapping film designed for ultra-fine surface finishing on extremely hard materials. Part of the 3M 661X series, this sheet features precisely graded diamond abrasive particles bonded to a dimensionally stable polyester film backing. The 0.10 micron grit rating places this film at the finest end of the lapping spectrum, making it suited for final-pass finishing and polishing applications where surface quality is critical. Each sheet measures 5.50 inches x 5.50 inches. Technicians use this film when repeatable, consistent surface finish results are required across multiple workpieces.

This lapping film is used in applications requiring the finishing of hard substrates such as ceramics, carbide, optical components, fiber optic connectors, and precision metal parts. It is commonly used in laboratory, manufacturing, and field service environments where surface finish tolerances are tight. The 661X series is available in several grades ranging from 0.10 to 30.0 micron, allowing technicians to step through progressive grits to achieve a final polished surface.

Compatibility

Designed for use on extremely hard materials including ceramics, carbide, and precision metal components requiring ultra-fine surface finishing. Part of the 3M 661X diamond lapping film series.

Installation Notes

Lapping film is typically handled by precision finishing technicians, toolmakers, or fiber optic splice technicians depending on the application. Secure the film flat against a lapping plate or backing surface before use to ensure even abrasive contact. Avoid folding or creasing the sheet, as this can cause inconsistent material removal. Follow the workpiece manufacturer or process specification for lapping sequence and intermediate grit steps before reaching the 0.10 micron final pass.
