Review: just as good as brand name papers, and better value ## Features - FITS FESTOOL RTS 400 & MIRKA DEOS – Serious Grit 5.25"" (80mm x 133mm) 14-Hole assorted grit hook & loop rectangle sanding sheets are compatible with the Festool RTS 400 and Mirka DEOS 353 electric detail sanders. These sanding sheets are ideal for sanding all surfaces, including wood, metal, drywall, epoxy, and painted surfaces. - HOOK & LOOP-BACKED FILM SHEETS – Our sanding sheets 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 sandpaper sheets 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 assorted grit sandpaper sheets 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C95DNBBM | | Are batteries included? | No | | Backing Type | Film | | Brand | Serious Grit | | Colour | Brown | | Compatible Devices | Festool RTS 400, Mirka DEOS 353 | | Customer Reviews | 4.7 4.7 out of 5 stars (165) | | Date First Available | 10 April 2024 | | Grit Material | Aluminum Oxide | | Grit Type | Dry | | Included Components | sandpaper | | Item Weight | 308 g | | Item model number | SG-133R-MG | | Manufacturer | Serious Grit | | Material | Aluminum Oxide Zirconia Alumina | | Model number | SG-133R-MG | | Net Quantity | 50.0 Count | | Number of Memory Sticks | 50 | | Product Dimensions | 13.3L x 8W Centimeters | | Size | Mixed Grit | | UPC | 850053215414 | ## Product Details - **Backing Type:** Film - **Brand:** Serious Grit - **Colour:** Brown - **Product Dimensions:** 13.3L x 8W Centimeters - **Size:** Mixed Grit ## Images ![Serious Grit - 3" x 5" (80mm x 133mm) 14-Hole Sanding Sheet Assortment - 80, 120, 150, 180, 220 Grit (10 of Each) - Fits Festool RTS 400 & Mirka Deos 353 - Hook & Loop Sandpaper - 50 Pack Box - Image 1](https://m.media-amazon.com/images/I/416DMZ-y4ML.jpg) ![Serious Grit - 3" x 5" (80mm x 133mm) 14-Hole Sanding Sheet Assortment - 80, 120, 150, 180, 220 Grit (10 of Each) - Fits Festool RTS 400 & Mirka Deos 353 - Hook & Loop Sandpaper - 50 Pack Box - Image 2](https://m.media-amazon.com/images/I/41S+jmyjkWL.jpg) ![Serious Grit - 3" x 5" (80mm x 133mm) 14-Hole Sanding Sheet Assortment - 80, 120, 150, 180, 220 Grit (10 of Each) - Fits Festool RTS 400 & Mirka Deos 353 - Hook & Loop Sandpaper - 50 Pack Box - Image 3](https://m.media-amazon.com/images/I/51ElvlD1p7L.jpg) ![Serious Grit - 3" x 5" (80mm x 133mm) 14-Hole Sanding Sheet Assortment - 80, 120, 150, 180, 220 Grit (10 of Each) - Fits Festool RTS 400 & Mirka Deos 353 - Hook & Loop Sandpaper - 50 Pack Box - Image 4](https://m.media-amazon.com/images/I/51JZ9t3jtbL.jpg) ![Serious Grit - 3" x 5" (80mm x 133mm) 14-Hole Sanding Sheet Assortment - 80, 120, 150, 180, 220 Grit (10 of Each) - Fits Festool RTS 400 & Mirka Deos 353 - Hook & Loop Sandpaper - 50 Pack Box - Image 5](https://m.media-amazon.com/images/I/51twTRyhISL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***N on 4 January 2026* These Serious Grit sanding sheets work perfectly with my Festool RTS 400.
