3M 7010325787 Aluminum Oxide Lapping Film Disc 5 in

Product Description

The 3M 7010325787 is a 5-inch diameter aluminum oxide lapping film disc engineered for precision surface finishing applications. Precisely graded aluminum oxide particles are coated onto a 3-mil polyester film backing, producing tight particle distribution and a consistent cut rate across the working surface. The result is a uniform finish on a wide range of substrates. This disc is sold individually and is used by machinists, fiber optic technicians, tool and die workers, and other trade professionals who require repeatable, controlled material removal.

This lapping film disc is suited for fine finishing and polishing work in industrial, manufacturing, and fiber optic connector preparation applications. The polyester film backing provides dimensional stability during use, making it appropriate for both hand-lapping and machine-assisted processes on metals, ceramics, optical components, and composite materials. The 5-inch diameter format fits standard lapping fixtures and backing plates common in shop and field environments.

Compatibility

Designed as a precision lapping disc for use with standard 5-inch lapping fixtures, backing plates, and holders common in metalworking, fiber optic, and fine surface finishing applications.

Installation Notes

Installation and use of lapping film discs should be performed by qualified machinists or technicians familiar with surface finishing procedures. Ensure the backing plate or fixture is clean and free of debris before mounting the disc to prevent uneven contact. Power down any motorized lapping equipment before changing discs. Follow applicable workplace safety guidelines for abrasive products, including eye protection and dust control.
