3M 7010325518 Diamond Lapping Film 3.0 Micron Roll

Product Description

The 3M 7010325518 is a diamond lapping film supplied in roll form, designed for precision surface finishing on extremely hard materials. Diamond particles are precisely graded to 3.0 micron and coated uniformly onto a polyester film substrate. This construction delivers a consistent, repeatable finish pass after pass, making it well suited for applications where surface quality tolerances are tight. The roll measures 3 inches wide by 50 feet long, providing ample working length for production or bench service environments. Technicians and skilled tradespeople in industries requiring fine abrasive finishing rely on this film where conventional abrasives fall short.

This lapping film is used for precision finishing of hard substrates including ceramics, carbide tooling, optical components, fiber optic connectors, and precision metal parts. The 3.0 micron grade positions it in the mid-to-fine range of the available spectrum, which spans from 0.10 to 30.0 micron. It is appropriate for intermediate and final finishing stages in both production and field service settings where a controlled, uniform scratch pattern is required.

Key Features

• Precisely graded 3.0 micron diamond abrasive particles for controlled, repeatable stock removal
• Diamond particles coated on a dimensionally stable polyester film backing
• Roll format at 3 inches wide by 50 feet long supports extended production runs
• Suitable for finishing extremely hard materials where conventional abrasives are ineffective
• Available across a broad grade range from 0.10 to 30.0 micron for multi-stage finishing systems

Compatibility

Designed for precision lapping and finishing of hard materials including ceramics, carbide, optical glass, fiber optic components, and hardened metals. Confirm abrasive grade and backing compatibility with the specific workpiece and lapping fixture before use.

Installation Notes

This film is typically applied by precision finishing technicians or tool-room professionals. Secure the film to a flat lapping plate or appropriate fixture before use, ensuring no wrinkles or gaps that could cause uneven material removal. Keep the work surface and film free of contamination from coarser abrasives to avoid scratching the finished surface. Follow the workpiece manufacturer's finishing sequence when using multiple micron grades.
