3M 7010360441 Aluminum Oxide Lapping Film Disc 5 in

Product Description

The 3M 7010360441 is a 5-inch diameter aluminum oxide lapping film disc engineered for precision finishing work. Precisely graded aluminum oxide particles are coated onto a 3-mil polyester film substrate, delivering tight particle size distribution and consistent cut rates across the service life of each disc. The result is a uniform, repeatable surface finish on a wide range of substrates. This disc is suited for use by machinists, fiber optic technicians, tool-and-die professionals, and other trade personnel who require controlled, micro-level material removal.

This lapping film disc is used in applications where surface finish consistency is critical, including fiber optic connector polishing, precision optical component finishing, and fine abrasive work on metal, ceramic, and composite substrates. The 3-mil polyester film backing provides dimensional stability during use. The disc is available in multiple micron grades including 0.30, 3.0, 5.0, 9.0, 12.0, and 30.0 micron, allowing the user to select the appropriate cut for each stage of a finishing sequence.

Installation Notes

This disc is installed by qualified technicians performing precision surface finishing or fiber optic polishing procedures. Ensure the backing plate or holder is clean and free of debris before mounting the disc. Follow the equipment manufacturer guidelines for disc attachment and polishing pressure to avoid uneven wear. Discard discs that show visible loading, tearing, or inconsistent surface texture.
