## Description

3.5-Inch (90mm) 7-Hole 120 Grit Sanding Discs - Fits Festool Rotex RO 90 - Heavy-Duty Hook & Loop Film Discs - Sandpaper for Random Orbital Sanders - 50 Pack Box

## Features

- FITS FESTOOL RO 90 – Serious Grit 3.5-Inch, 7-Hole 120 grit 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 120 grit sandpaper 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.

    It really does make a difference
  

*by S***R on Reviewed in the United States on July 8, 2024*

I used to think that for throw away items like this I would save some money and go to “that store” where everything comes from China. After all, it’s only sandpaper so how big of a difference could there be? Well, a lot apparently.I bought several boxes in various grits to use with my Festool Rotex 90 sander. I wasn’t interested in paying Festool prices for their own sandpaper. This paper is made specifically for my sander and all the holes line up perfectly. I was very impressed with how much longer it lasted and how it didn’t get clogged up. I compared to some of the factory paper I had and I could tell no difference other than the color. Highly recommend.

    I have several festool sanders. This product fit my RO 90 like a glove. After several hours of sanding I can say these sanding discs are the only ones I have found comparable to the more expensive FT discs. I usually don’t leave product reviews but this product not only impressed me but made me want to share my experience with others!
