3M-769F Fan Discs

The 3M™ 769F Fan-Shaped Abrasive Disc was developed for high-performance grinding applications where high removal rates, consistent results, and long service life are critical. It is ideal for professional users who want to work efficiently while ensuring a uniform surface finish.

It utilizes 3M™ precision-shaped ceramic grit, whose special geometry actively cuts into the metal. Unlike conventional abrasive grains, the material is not displaced but cleanly removed. This allows for rapid work progress—even with reduced contact pressure—and minimizes heat generation, which is particularly advantageous when working with stainless steel.

The fiber-reinforced, overlapping flaps wear down in a controlled manner and continuously release fresh abrasive mineral during the grinding process. This ensures a consistent cutting speed throughout the entire service life of the disc. At the same time, the flexible flap structure results in smooth grinding behavior and a finer finish than with comparable fiber discs of the same grit.

The 3M™ 769F Fan Disc enables grinding and finishing in a single step for many applications. It is particularly suitable for carbon steel, stainless steel, and other heat-sensitive alloys and is designed for use on angle grinders. This reduces tool changes, speeds up processes, and lowers costs.
