3M-769F Fan Discs

The 3M™ Fan Disc 769F offers a powerful combination of durability and high grinding performance. Its innovative, precision-shaped ceramic grain ensures that the disc cuts quickly while lasting longer than conventional zirconia corundum variants. During operation, the flaps break open in a controlled manner, continuously releasing new, sharp abrasive particles—this keeps the cutting speed constant and ensures consistent work progress.

The unique flap structure ensures extensive use of the abrasive material and produces a uniform grinding pattern. At the same time, only minimal contact pressure is required, making the disc ideal for delicate metals such as stainless steel or heat-sensitive alloys. In many applications, it can handle both rough grinding and finishing—an advantage that saves time and increases efficiency.
