3M Cubitron 3 Fan-Shaped Sanding Disc 1169F

The 3M™ Cubitron™ 3 Flap Disc 1169F is designed to make grinding tasks more efficient and predictable. It combines powerful material removal with a consistent surface finish and is ideal for professional use in metalworking.

It utilizes the newly designed 3M precision-shaped grain with a curved side profile. This grain geometry ensures that new, sharp-edged cutting surfaces are continuously formed during grinding. As a result, the abrasive maintains a cutting edge throughout its service life and retains its performance over the entire duration of use.

The flaps are designed to wear in a controlled and uniform manner. This continuously exposes fresh abrasive mineral, enabling consistent material removal and preventing performance fluctuations. At the same time, heat input is reduced—a clear advantage when working with stainless steel, structural steel, and heat-sensitive alloys.

Thanks to its flexible design, the flap disc adapts perfectly to edges, contours, and transitions. It covers numerous work steps, from weld seam finishing and deburring to surface preparation and fine transitions. In many applications, grinding and finishing can be performed in a single operation, saving time and abrasive material.
