The Festool ROTEX RO 90 DX is a powerful and versatile geared eccentric sander combining four sanding functions in one compact machine. Designed for coarse sanding, fine sanding, polishing, and corner sanding, it delivers professional results across a wide range of surfaces and applications.
Thanks to the FastFix interface, the round sanding pad can be quickly swapped for a triangular pad, transforming the tool into a delta sander for working in tight spaces, corners, and edges. Its compact size makes it ideal for vertical surfaces and overhead work while maintaining excellent control and performance.
Built around the trusted ROTEX principle, this multi-function sander ensures rapid material removal, fine finishing capability, and polishing versatility in one lightweight system-compatible solution.
