3M Cubitron 3 Fan-Shaped Sanding Disc 1169F

The 3M™ Cubitron™ 3 Fan-Shaped Sanding Disc 1169F was developed for professional sanding tasks where efficiency, control, and consistent results are paramount. It is ideal for daily use in metalworking and supports productive workflows.

It utilizes the redesigned 3M precision-shaped grain with a curved side geometry. This special shape ensures that the grain self-renews in a targeted manner during grinding. New, sharp cutting edges are constantly created, which remove material cleanly and enable consistently high grinding performance.

The lamellar structure is designed for even wear and continuously releases fresh abrasive mineral. This keeps the removal rate stable throughout the disc’s entire service life. At the same time, heat generation is reduced, which contributes to safe and clean results, particularly when working with stainless steel, structural steel, and other heat-sensitive alloys.

Thanks to its flexible design, the flap disc adapts perfectly to edges, contours, and transitions. It covers a wide range of applications—from weld seam grinding and deburring to blending and surface preparation. In many cases, multiple work steps can be performed without changing discs, saving time and increasing efficiency.
