3M 7100024100 Microfinishing Psa Film Disc 268L 5 Inch

Product Description

The 3M 7100024100 is a microfinishing PSA film disc from the 268L series, designed for precision surface finishing across a wide range of materials. It uses micron-graded aluminum oxide mineral bonded to a durable polyester film backing. This combination delivers a fast cut rate and a consistent, uniform finish on wood, solid surface composites, metals, plastics, and fiberglass. The pressure-sensitive adhesive backing allows quick, secure mounting to compatible random orbital and disc sanders. Licensed trades and finishing professionals use this disc where tight surface tolerances and repeatable finish quality are required.

This disc suits residential and light commercial finishing applications involving hardwoods, softwoods, metals, plastics, and fiberglass substrates. It is well suited to cabinet shops, metal fabrication, auto body prep, and composite surface work. The 5-inch diameter and 12000 RPM rating make it compatible with standard 5-inch PSA backing pads found on common finishing equipment. It may be run wet to minimize loading and reduce airborne particulate during sanding operations.

Installation Notes

This disc is installed by a finishing professional or abrasives technician. Before mounting, ensure the backing pad is clean and free of debris to allow full PSA contact. Confirm the tool is rated for the disc diameter and RPM before operation. When running wet, verify the sander and work environment are appropriate for wet use.
