3M 7000139410 Abrasive Disc 5 Inch 12000 Rpm

Product Description

The 3M 7000139410 is a 5-inch hook-and-loop abrasive disc designed for fast scratch removal on automotive metal components and other metal surfaces. Built on an X-weight cloth backing with a macroreplicated aluminum oxide grain structure, this disc delivers consistent cutting action and a controlled finish across multiple substrates. The microreplicated abrasive design channels swarf away from the work surface to reduce loading and minimize heat buildup, which extends disc life and keeps surface temperatures manageable. It is intended for use by auto body technicians, metal fabricators, and finishing professionals working on white metal and related surfaces.

The 7000139410 suits automotive refinishing and metal prep applications where a consistent, predictable finish is required. The hook-and-loop attachment system makes disc changes fast during high-volume production or detail work. The disc is rated to 12000 RPM, making it compatible with standard random orbital and disc sanders used in collision repair shops and fabrication environments. Each disc is sold individually, with a minimum order quantity of 50 units.

Installation Notes

This disc is installed by trade professionals and auto body technicians using compatible hook-and-loop backing pads. Confirm the sander backing pad diameter matches the 5-inch disc before use. Do not exceed the 12000 RPM speed rating. Inspect the disc for tears or delamination before each use and discard any disc showing damage to the backing or abrasive layer.
