3M Cubitron 3 Fan-Shaped Sanding Disc 1169F

The 3M™ Cubitron™ 3-Flap Sanding Disc 1169F was developed to perform sanding tasks efficiently, with precision, and cost-effectively. It is suitable for professional users who expect consistently high performance across a wide range of metalworking applications.

It utilizes the newly designed 3M precision-shaped grain with curved sides. This special grain structure ensures that new cutting edges are continuously formed during the grinding process. As a result, the disc actively removes material rather than displacing it, delivering consistent performance throughout its entire service life.

The flaps are designed to wear evenly and continuously release fresh abrasive grain. The result is stable material removal without a drop in performance, as well as reduced heat generation on the workpiece. This has a positive effect on machining quality, 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 covers numerous work steps—from weld seam finishing and deburring to blending and surface preparation. In many applications, grinding and finishing can be combined, reducing working time and tool changes.
