One investment 4 tools

THE ROTEX RO 90 DX is gear-driven eccentric sander, random orbital sander, polisher and detail sander in one machine. The versatility reduces your purchasing costs and increase the flexibility and efficiency of your work.

Intelligent electronics

Festool's MMC electronics control the smooth start-up, adapt the speed to the material and keep it constant. Infinitely adjustable, it ensures consistent work regardless of the material.

No kickback

The Festool pad protector makes it possible to sand right up against the edge. The protector is available in set of different sizes to suit virtually all window frames for perfect results in no time at all without time-consuming masking.

Better results, faster

The 90mm pad diameter is optimised for window frames and tongue-and-groove joints where work is done vertically or in tight spaces. The delta sanding pad can be used three times longer simply by rotating. Pad and abrasive changes are tool free.

Perfect polishing

The ROTEX rotary motion, combined with Festool's range of polishes and polishing sponges, produce gleaming, hologram-free results with minimal heat. There is no compromise on finish quality with the RO 90 4-in-1.

Breathe easy

A Festool Dust Extractor hose can be easily attached to the integrated dust extraction port to ensure immediate uptake of dust, leaving the work piece and your lungs clear.
