Serious Grit's 3.5" (90mm) 7-Hole hook and loop sanding discs are the perfect match for your Festool Rotex RO 90 sander.

With their high quality film construction, durable hook and loop backing, and proprietary zinc stearate anti-clog coating, these discs won't let you down in your shop.

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 – Serious Grit 3.5-Inch, 7-Hole hook & loop sanding discs are compatible with the Festool Rotex RO90 90mm random orbital sander. These sanding discs are ideal for sanding all surfaces, including wood, metal, drywall, epoxy, and painted surfaces.
  • 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.

This has been one of our most requested sizes from our loyal fan base and we're thrilled to finally offer them for sale.
