3M 7000118212 Diamond Lapping Film 0.10 Micron 6x6 Sheet

Product Description

The 3M 7000118212 is a diamond lapping film sheet designed for precision surface finishing of extremely hard materials. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film backing, producing a consistent cutting action across the entire sheet surface. At 0.10 micron grit, this sheet delivers ultra-fine finishing suitable for achieving near-optical surface quality on carbide, ceramic, glass, and similar hard substrates. Each sheet measures 6.0 inches x 6.0 inches and is sold individually. Technicians and machinists rely on this film where repeatability and surface consistency are critical process requirements.

This lapping film is used in precision finishing applications across optics, fiber optic connector polishing, cutting tool reconditioning, and advanced materials fabrication. The 0.10 micron grade is typically the final finishing step in a progressive lapping sequence, following coarser diamond or aluminum oxide film grades. It is appropriate for both bench lapping on flat plates and fixture-guided polishing operations where controlled stock removal at the sub-micron level is required.

Key Features

• 0.10 micron precisely graded diamond abrasive for ultra-fine surface finishing
• Polyester film backing provides dimensional stability and consistent particle contact
• 6.0 inches x 6.0 inches sheet size suits flat lapping plates and fixture polishing setups
• Repeatable finish quality across multiple uses on extremely hard substrate materials
• Part of a multi-grade system ranging from 0.10 to 30.0 micron for progressive stock removal

Compatibility

Designed for use on extremely hard materials including carbide, ceramic, glass, and similar substrates requiring sub-micron surface finishes. Intended for use in progressive lapping sequences alongside coarser diamond lapping film grades in the same product family.

Installation Notes

Diamond lapping film is typically applied by skilled machinists, optical technicians, or tool and die professionals in controlled finishing environments. Secure the sheet flat against a lapping plate or fixture to prevent wrinkling and ensure uniform abrasive contact. Use appropriate lapping fluids as recommended for the substrate being finished, and always progress through grades from coarser to finer to achieve the target surface finish. Handle with clean hands or gloves to avoid contaminating the abrasive surface.
