3M Cubitron 3 Fan-Shaped Sanding Disc 1169F

The 3M™ Cubitron™ 3 Fan-Shaped Abrasive Disc 1169F was developed for users who rely on consistent performance and high efficiency during grinding operations. It combines powerful material removal with controlled operation and is ideal for professional continuous use.

It utilizes the newly designed 3M precision-shaped grain with an optimized, curved side structure. This special grain shape ensures that the abrasive continuously renews itself during operation. New, sharp cutting edges are constantly formed, allowing the disc to cut cleanly through the metal and maintain its performance throughout its entire service life.

The flaps are designed to wear evenly, constantly releasing fresh abrasive grain. This enables consistent material removal without fluctuations in performance while simultaneously reducing heat input to the workpiece. This ensures reliable and reproducible results, particularly when working with stainless steel, structural steel, and other 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 finishing and deburring to blending and surface preparation. In many cases, multiple processing steps can be completed in a single operation, saving time and reducing process costs.
