3M 7100199424 5 Inch 120 Grit Ceramic Ao Abrasive Disc

Product Description

The 3M 7100199424 is a 5-inch hook-and-loop abrasive disc designed for automotive paint preparation and body repair work. This disc uses a blended mineral construction that combines ceramic grain with aluminum oxide abrasive, producing consistent cut and finish across a range of sanding stages. The 120-grit rating makes it well-suited for intermediate material removal and surface leveling. An anti-loading coating keeps the cutting surface clear of dust and debris, helping the disc maintain its cut rate through extended use. Professional auto body technicians and painters are the primary installers of this disc.

This disc is built for the full automotive refinishing process, from bare substrate work through paint prep. The multi-hole pattern is engineered for dust extraction, aligning with most standard backup pads used in collision repair and refinishing shops. The Hookit attachment system allows fast disc swaps without tools, reducing downtime during production work. It is suitable for use on painted surfaces, primers, body filler, and bare metal in both production shop and single-vehicle repair scenarios.

Installation Notes

Mount the disc onto a compatible 5-inch hook-and-loop backup pad before use. Verify that the backup pad surface is clean and free of debris to ensure full engagement of the Hookit attachment. Operate at speeds within the rated limits of both the disc and the backup pad. Inspect the disc for wear, tears, or loading before each use and replace when cutting performance decreases.
