3M Cubitron 3 Fan-Shaped Sanding Disc 1169F

The 3M™ Cubitron™ 3 Fan-Shaped Grinding Disc 1169F supports efficient workflows in metalworking and ensures reliable results for a wide variety of grinding tasks. It is designed for consistent performance and high cost-effectiveness—even with intensive use.

It utilizes the newly developed 3M precision-shaped grain with an optimized, curved side profile. This special grain geometry causes the abrasive to self-renew in a targeted manner during operation. New, sharp cutting edges are constantly formed, which remove material cleanly and enable consistently high removal rates.

The flaps are designed to wear evenly, continuously exposing fresh abrasive grain. This keeps performance stable throughout the entire service life while simultaneously reducing heat input into the workpiece. This has a positive effect on machining quality, particularly with stainless steel, structural steel, and sensitive alloys.

Thanks to its flexible design, the flap disc adapts perfectly to edges, contours, and transitions. It is suitable for a wide range of applications—from powerful weld bead grinding to clean transitions and preparatory finishing work. In many cases, multiple machining steps can be performed without changing discs, which saves time and reduces process costs.
