3M Cubitron 3 Fan-Shaped Sanding Disc 1169F

The 3M™ Cubitron™ 3 Fan-Shaped Sanding Disc 1169F is designed for high efficiency and reliable results in metalworking. It supports consistent sanding processes and ensures that performance remains constant even during extended use.

Equipped with the advanced 3M precision-shaped grain with a curved side profile, the disc enables particularly effective material removal. During use, the grain renews itself in a controlled manner, continuously forming new, sharp cutting edges. As a result, the disc operates by cutting rather than grinding—a clear advantage over conventional flap discs made of zirconia or aluminum oxide.

The lamellar structure is designed to wear evenly and continuously expose fresh abrasive grain. This ensures consistent material removal throughout the entire service life while simultaneously reducing heat input into the workpiece. This contributes to clean and controlled results, particularly when working with stainless steel and heat-sensitive alloys.

Thanks to its high adaptability, the flap disc is suitable for a wide variety of applications—from heavy-duty weld bead grinding to precise transition and preparation work. In many cases, multiple work steps can be performed without changing discs, which saves time and reduces abrasive consumption.
