The RO 90 DX is the newest addition to Festool's line of Rotex sanders. If you're already familiar with the advantages of Rotex sanders, you may just be curious what's so special about the new model.

The only professional sander that sands open spaces as easily as it conquers corners. How do you move seamlessly between rough sanding and final sanding without switching sanders? It is easy when you own a Rotex multi-mode sander.

The design of this multipurpose sander is nothing short of an engineering marvel. Use the aggressive action to quickly and efficiently remove wood, paint, or varnish. Switch to the fine setting for final finishing. Equip your Rotex with polishing pads, sponges, felts or sheepskin and get astonishing finishes that gleam with brilliance.

With the new RO 90 DX, add the ability to swap the round pad for a delta-shaped pad to reach deep into corners and crevices. Transform rough surfaces with startling power, stripping stubborn paints and other coatings, and making you the master of all materials. The aggressive mode delivers material removal like that of a grinder and makes your belt sander look like a toy. Shaving off hours of sanding, you quickly and easily achieve astonishing results.

When sanding on or near edges, use the optional hard pad to preserve a crisp edge on the material. It is also effective for coarse sanding when shaping or producing contours is the intended effect.

The one sander that conquers corners as easily as it sands open spaces.
