3M 7010298844 Diamond Lapping Film 662XW 1.0 Micron Roll

Product Description

The 3M 7010298844 is a diamond lapping film designed for precision surface finishing and material removal in tight-tolerance applications. Sold as a 1-inch wide by 50-foot roll in a 1.0 micron grade, this film uses a higher diamond concentration and a stronger resin bond compared to standard diamond lapping film. The result is a faster cut rate and longer service life. It is used by technicians and machinists who need consistent, repeatable surface finishes on hard substrates such as ceramics, carbide, glass, and hardened metals.

This film is suited for fine lapping, polishing, and deburring operations in precision manufacturing, fiber optic connector finishing, and tool and die work. The roll format allows users to cut custom lengths for lapping fixtures, hand lapping, or automated finishing equipment. The 1.0 micron grade is appropriate for intermediate-to-final polishing stages where a refined surface finish is required before moving to sub-micron grades.

Key Features

• Higher diamond concentration for increased cut rate over standard diamond lapping film
• Stronger resin bond delivers added durability and extended usable life
• 1.0 micron abrasive grade for intermediate-to-final precision polishing
• Roll format (1 inch wide x 50 feet) allows custom length cutting for varied fixtures
• Compatible with hard substrates including ceramics, carbide, and hardened metals

Compatibility

Designed for use with lapping fixtures, hand lapping setups, and automated finishing equipment requiring a 1-inch wide abrasive film in a 1.0 micron grade. Also available from 3M in 0.50, 1.50, 3.0, 6.0, and 9.0 micron grades for multi-stage finishing sequences.

Installation Notes

This film is typically used by machinists, precision grinders, or fiber optic technicians working with lapping fixtures or hand-lapping plates. Before use, ensure the lapping surface and workpiece are clean and free of contamination that could embed into the film or scratch the substrate. Cut lengths from the roll using a clean straight edge to avoid tearing the film backing. Do not apply excessive pressure, as diamond lapping films are designed to cut efficiently under light, controlled loads.
