3M Cubitron 3 Fan-Shaped Sanding Disc 1169F

The 3M™ Cubitron™ 3 Fan-Shaped Abrasive Disc 1169F is designed for demanding grinding tasks in metalworking. It supports efficient workflows and ensures consistent results—even with intensive use and varying applications.

It utilizes the newly developed 3M precision-shaped grain with a specially designed, curved side profile. This grain geometry enables cutting-edge material removal and ensures that new, sharp cutting edges continuously form during grinding. As a result, the disc’s performance remains consistently high throughout its entire service life.

The flaps are designed to wear in a controlled manner, continuously exposing fresh abrasive material. This ensures uniform material removal while reducing heat build-up on the workpiece. This offers significant advantages, particularly when working with stainless steel, structural steel, and other temperature-sensitive materials.

Thanks to its flexible design, the flap disc adapts perfectly to edges, transitions, and contours. It is highly versatile—from weld seam finishing and deburring to blending and surface preparation. In many cases, multiple steps can be completed in a single pass, saving time and reducing abrasive consumption.
