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 | | Backing Type | Film | | Brand Name | Serious Grit | | Colour | Brown | | Compatible Devices | Festool RTS 400, Mirka DEOS 353 | | Compatible Material | Metal | | Customer Reviews | 4.8 4.8 out of 5 stars (102) | | Grit Material Type | Aluminum Oxide | | Grit Type | Dry | | Item Diameter | 3.15 Inches | | Item Dimensions | 13.3 x 8 x 0.3 Centimeters | | Item Dimensions L x W | 13.3L x 8W Centimeters | | Manufacturer | Serious Grit | | Material Type | Aluminum Oxide Zirconia Alumina | | Model Number | SG-133R-MG | | Number of Items | 50 | | Part Number | SG-133R-MG | | Set Name | Mixed Grit | | Size | Mixed Grit | | UPC | 850053215414 | | Unit Count | 50.0 Count | | Whats in the box? | sandpaper | ## 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/51prix948tL.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/51ktpsLmBRL.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/51f5Ak4c0NL.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/512echLKUFL.jpg) ## Available Options This product comes in different **Style** options. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/705946607-serious-grit-3-x-5-80mm-x-133mm-14-hole](https://www.desertcart.sg/products/705946607-serious-grit-3-x-5-80mm-x-133mm-14-hole) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-04*
