Serious Grit - 14-Hole 220 Grit Sanding Sheets (80x133mm) for Festool RTS 400 & Mirka Deos 353 – Heavy-Duty Film Backed, 50 Pack

Premium sanding sheets built for demanding projects

Serious Grit delivers a reliable 14-hole, 220-grit sanding sheet designed to work with popular compact sanders like the Festool RTS 400 and Mirka Deos 353. The sheets use a tough polyester film backing and aluminum oxide abrasive, creating a sturdy disc that can stand up to mid- to heavy-duty sanding on a variety of materials. If you regularly switch between wood, metal, drywall, epoxy, or paint, these sheets offer a consistent surface profile with fewer edge frays and less heat buildup during use.

Key benefits in real-world use

• Compatible with 14-hole dust collection systems to help maintain a cleaner workspace.
• Film-backed construction enhances rigidity and heat dissipation for a steadier finish.
• Durable, tear-resistant polyester film resists edge wear when sanding around corners.

In addition to compatibility, Serious Grit sheets feature a proactive anti-clog coating that sheds dust before it clogs the abrasive surface, helping maintain cutting power when paired with a dust extractor or vacuum. This means more consistent material removal and a smoother final result over longer sessions.

Durability, finish, and versatility

The film-based design yields a flatter, stronger disc sense compared to paper or mesh alternatives, contributing to a more uniform finish. The anti-clog coating keeps the entire surface active longer, supporting steady cutting power and a swirl-free appearance across different materials and coatings.

Whether you’re performing wet sanding, dry sanding, or light auto body work involving paint removal, these sheets are engineered to stay effective across the entire sheet, reducing the need for frequent sheet changes and helping you complete tasks more efficiently.

How to maximize results

• Pair with a compatible dust extraction system for best dust control.
• Choose this 220 grit for preparing surfaces before finishes or touch-ups.

Included in the package is a 50-pack box, offering ample sheets for multiple projects or ongoing use in a workshop. This combination of durability, compatibility, and finish quality makes Serious Grit a solid option for professionals and hobbyists seeking dependable sheet sanding performance.
