Festool Rotex RO 125 Dual-Mode Sander

Festool Sanders

Versatile and easy to maneuver.

Festool's Rotex family of sanders offers much more than just another one-dimensional sanding solution, delivering instead a completely different approach to sanding and finishing tasks. It is no exaggeration to say that the Rotex and CT Dust Extractor have the ability to turn sanding into an enjoyable experience.

This sander gives you everything Rotex has to offer in a compact, lightweight, and powerful package. The RO 125 puts 500 watts of power, dual-mode sanding, and triple-function performance into a comfortable, 4.4 pounds. This 5" sander does it all—coarse and fine sanding, plus polishing. The RO 125 features near-total dust extraction, exceptional ergonomics, and many other advanced features. A small but rugged sander, the RO 125 is ready for whatever you want to throw at it.

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.

If you still have questions, please feel free to contact us or your preferred Festool dealer for more information.
