The Festool 497481 Interface Pad for RO 90 DX is a soft 90 mm interface pad made to sit between your abrasive disc and sanding pad. This is an interface pad designed for profile sanding, contour sanding, and superfine finish work where you need the abrasive to ride the surface instead of digging in. Model Number 497481. If you use a Festool RO 90 DX or another Festool 90 mm sander or polisher on curved panels, shaped trim, or delicate surfaces, this accessory gives you a more forgiving sanding setup.

The big reason to use an interface pad is control. Festool built this one with extreme softness so the abrasive can float over the workpiece. In practical terms, that means smoother results on rounded edges, molded profiles, and subtle contours where a standard direct-mounted disc can leave pressure marks or cut through too fast. For superfine sanding, that softer layer also helps absorb some of the input from both the user and the machine, which leads to lighter abrasion and a better finish.

This pad uses Festool's StickFix hook and loop surface, so disc changes stay quick and simple. That is especially useful when you are moving through multiple grits during finish prep or paint correction work. Instead of fighting with worn discs or wasting partially used abrasives, you can pull one off, switch, and keep moving. On detail sanding jobs, that kind of small time savings adds up fast.

Festool also carries over its Jetstream hole pattern here, which matters more than a lot of people think on finish work. Better airflow means dust has a clearer path away from the surface, which helps reduce loading on the abrasive and keeps the cut more even. Cleaner extraction also means less stray dust trapped under the disc, so you are less likely to chase swirl marks or random scratches caused by debris.

Size and fitment are straightforward. The pad measures 3-1/2 inches in diameter and 15 mm in height, and it is suitable for the RO 90 DX. Festool also states it fits all Festool 90 mm sanders and polishers, which makes it a useful accessory if you already work inside that platform. It is not a power tool by itself. It is a job-specific finishing accessory that changes how your existing sander behaves on sensitive surfaces.

This is a smart buy for auto body work, finish carpentry, painted surface prep, and any sanding job where surface quality matters more than aggressive stock removal. If you mainly sand flat, open areas and want maximum cut, you probably will not leave this on all the time. But when the work turns curved, shaped, or delicate, the Festool 497481 Interface Pad for RO 90 DX is exactly the kind of accessory that helps you get a cleaner result without overworking the surface.
