3M-769F Fan Discs

The 3M™ 769F Fan Disc was developed for demanding grinding applications that require high removal rates, long service life, and a consistent surface finish. It is a high-performance solution for professional users who want to work efficiently without compromising on quality.

Equipped with 3M™ precision-shaped ceramic grit, the flap disc actively cuts the material rather than simply displacing it. The sharp-edged grit structure ensures fast material removal while reducing contact pressure. This keeps the disc performing at its best for longer and enables controlled, clean work.

The overlapping flaps wear down evenly, continuously exposing new abrasive mineral. This keeps the cutting speed constant throughout the disc’s entire service life. At the same time, the flexible flap construction provides a cushioned contact surface that produces a uniform grinding pattern and enables a finer finish than comparable fiber discs of the same grit size.

The 3M™ 769F Fan Disc is particularly suitable for machining structural steel, stainless steel, and other heat-sensitive alloys. It combines grinding and finishing in a single step, thereby replacing multiple abrasives. This saves time, reduces tool changes, and noticeably increases productivity. Designed for use on angle grinders, it is both versatile and economical.
