3M Cubitron 3 Fan-Shaped Sanding Disc 1169F

The 3M™ Cubitron™ 3 Fan-Shaped Grinding Disc 1169F was developed for the most demanding requirements in metalworking and impresses with an exceptional combination of removal rate, service life, and flexibility. It is ideal for users who want to work efficiently while achieving a clean, controlled finish.

At the heart of the disc is the advanced 3M precision-shaped grain with a curved geometry. This special grain shape ensures that new cutting edges form continuously during grinding. As a result, the removal rate remains consistently high without the disc losing its aggressiveness. Compared to conventional flap discs made of aluminum oxide or zirconia, the 1169F works noticeably faster and more efficiently.

The flaps wear down in a controlled manner at the edges, continuously exposing fresh abrasive material. The result is consistent performance throughout the entire service life. At the same time, the cutting action reduces heat generation, which is particularly advantageous for stainless steel and other heat-sensitive alloys.

Thanks to its high adaptability, the 3M™ Cubitron™ 3 Fan-Shaped Abrasive Disc 1169F is suitable for a wide range of applications—from coarse grinding to fine transitions and surface preparation. In many cases, grinding and finishing can be combined in a single step, saving time and minimizing disc changes.
