Dynabrade DG922 Film Backed Abrasive Disc

Why a film backing

Paper deforms, creases on edges and tears. A film keeps a perfectly constant thickness: all the grains are at the same level and work together, giving a uniform scratch with no stray scratches. Film also resists water and tearing at the edges of parts.

It is a backing of choice for finishing before painting and for fine grits, where the slightest stray scratch would show.

A very wide range

From P40 to P2000, the DG922 covers the whole sanding sequence: P40 to P80 for levelling, P120 to P240 for preparation, P320 to P600 for preparation before painting, P800 to P2000 for finishing before polishing.

Choosing the hole pattern

The hole pattern must match the sander pad for extraction to work. Plain discs suit machines without extraction and very small diameters.
