## Description

3.5-Inch (90mm) 7-Hole Sanding Discs Assortment - 80, 120, 150, 180, 220 Grit (10 of Each) - Fits Festool Rotex RO 90 - Heavy-Duty Hook & Loop Film Discs - 50 Pack Box

## Features

- FITS FESTOOL RO 90 – Serious Grit 3.5-Inch, 7-Hole assorted 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 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good Value
*by M***N on February 24, 2025*

Great sandpaper for my Rotex 90 Very happy with product and price

### ⭐⭐⭐⭐⭐ It really does make a difference
*by S***R 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.

### ⭐⭐⭐⭐⭐ Last longer than Festool
*by J***Y on May 25, 2024*

I have been using Festool professionally, always using Festool sanding sheets until I tried Serious Grit. In my profession I use western red cedar making and remaking the same things over and over again over those years. Very seldom do I use the sanding paper flat to the surface and I mostly use it at an angle to get more sanding power. The Serious Grit round sheets last much much longer. I waited a few weeks to write this review to really test them out. I'm convinced.
