The Festool 492126 RO125 FEQ StickFix Sanding Pad, Supersoft, 125mm (5") is a replacement sander backing pad made for the Festool RO 125 FEQ ROTEX sander. This is a sander backing pad designed for profile sanding, contour sanding, and other surface prep work where a softer contact face helps you avoid cutting too aggressively. Model Number 492126. If you are sanding roundovers, cambers, or shaped parts, this is the pad that makes the machine easier to control.

The big reason to choose this pad is simple: the supersoft face is more forgiving than a standard pad. On curved panels, profiled trim, and automotive bodywork, that softer support helps the abrasive follow the surface instead of flattening details or digging at the edges. Festool specifically positions this version for heavy roundings and cambers, so it is a practical upgrade when the stock setup feels too firm for finish-sensitive work.

Festool built this pad around its StickFix hook and loop system, which keeps abrasive changes quick and straightforward. That matters on real jobs because you can switch grits fast, reuse partially used discs, and keep working without fighting the backing pad. The FastFix connecting thread also means tool-free pad changes on the RO 125 FEQ, so moving from one sanding setup to another does not turn into a wrench-and-bench routine.

Dust control is another real selling point here. The Jetstream design and 8-hole pattern are meant to support effective dust removal through the pad. In practical terms, better airflow helps keep dust from packing between the abrasive and the workpiece, which can improve finish quality and extend the life of both the disc and the pad. That is especially useful during finer sanding where trapped dust can leave swirl marks or load up the abrasive early.

Material choice matters on accessories like this, and Festool uses heat-resistant MPE foam for consistent wear and longer service life. On extended sanding sessions, heat buildup can shorten the life of cheaper pads or make them wear unevenly. A resilient foam body helps the pad hold its shape better and keep contact more uniform across the sanding face.

Compatibility is clear and specific: this pad is suitable for the Festool RO 125 FEQ. It uses the FastFix connection and works with StickFix abrasives in the 125 mm class. That makes it a direct fit for users already invested in the Festool sanding system, especially anyone pairing their sander with Festool abrasives and dust extraction for cleaner operation.

This accessory makes the most sense for automotive refinishing, woodworking, finish carpentry, and anyone doing detail sanding on shaped surfaces. If most of your work is dead-flat panel sanding, a firmer pad may make more sense. But if you need the sander to stay controlled on curves, contours, and delicate profiles, this supersoft backing pad is the right call.
