3M Cubitron 3 Fan-Shaped Sanding Disc 1169F

The 3M™ Cubitron™ 3 Fan-Shaped Sanding Disc 1169F was developed to perform grinding tasks in metalworking efficiently, evenly, and reliably. It is particularly suitable for professional users who value consistent performance and reproducible results.

The basis for its high performance is the advanced 3M precision-shaped grain with a curved geometry. This special grain shape ensures that new, sharp cutting edges are continuously formed during use. As a result, the abrasive works effectively over the long term and achieves consistent, high material removal throughout its entire service life.

The lamellar structure promotes controlled wear and continuously exposes fresh abrasive grain. This keeps the removal rate stable while simultaneously reducing heat generation. This is particularly advantageous when machining stainless steel, structural steel, and other heat-sensitive materials.

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 steps can be completed in a single pass, saving time and reducing abrasive consumption.
