Serious Grit 3.5″ (90mm) ceramic sanding discs deliver fast, clean, and consistent performance for pros working with wood, metal, paint, or filler.
Designed to fit the Festool RO90 and any 90mm random orbital sander, these discs make your sanding easier and more efficient. The advanced ceramic abrasive cuts more than 40%+ faster and lasts longer than traditional abrasives, helping you get through tough jobs with fewer disc changes.
The universal multi-hole pattern works with any 3.5″ hook and loop sander and doesn’t require alignment—just stick it on and start sanding. It pulls dust through your pad for a cleaner surface and better finish.
A tear-resistant film backing keeps the disc flatter for more even sanding, especially on edges and corners, and holds up under both wet and dry conditions.
The hook and loop attachment locks in tight while you work and removes cleanly when you’re ready to switch grits. If you want a disc that fits right, cuts fast, and holds up through real-world use, this is it.
Each box contains 50 sanding discs, except for the 40 grit and 60 grit boxes, which contain 25 discs each.
Mixed grit box includes 10 discs of each – 80, 120, 150, 180, and 220 grit.
- FITS FESTOOL RO 90 – Universal laser-cut multi-hole pattern fits Festool RO90 Rotex sanders and any other random orbital sander with a 3.5″ / 90mm hook & loop backing pad. No need to line up holes, just slap it on and start working.
- HOOK & LOOP-BACKED FILM DISCS – Our discs are constructed with a heavy-duty polyester film backing material between the aluminum oxide abrasive grain and the hook and loop backing. This premium material creates a stronger disc, with more effective heat dissipation, and a better finish. These wet/dry discs are perfect for woodworking, auto body work including paint removal and wet sanding, and more.
- MORE DURABLE – Our sanding discs are made with polyester film construction which makes them nearly impossible to tear. No more frayed or torn edges when sanding around corners.
- LESS CLOGGING – Our proprietary heat-treated zinc stearate anti-clog coating sheds dust before it has a chance to clog up your disc, making these discs virtually dust free when paired with a dust extractor or vacuum system.
- SMOOTHER FINISH – The film construction creates a flatter, stronger disc that produces a better finish vs paper, mesh, or net sanding discs. With our anti-clog coating, the entire surface area of the disc stays effective longer, which improves cutting power and leads to a more consistent swirl-free finish.
