Serious Grit - 14-Hole 80 Grit Sanding Sheets, 80mm x 133mm, Fits Festool RTS 400 & Mirka Deos 353 – 50 Pack

Overview

Discover Serious Grit 14-hole 80-grit sanding sheets, crafted for durability and consistent results. Sized at 80mm x 133mm (approximately 3" x 5"), these heavy-duty hook & loop film sheets are designed to fit popular detail sanders such as Festool RTS 400 and Mirka Deos 353. The 14-hole pattern aids dust extraction and helps maintain a steady cutting pace, making them suitable for a range of surfaces from wood to metal and painted finishes.

Built for real-world tasks, this series leverages a film-backed abrasive that stays flat and true under pressure. The result can feel like a more controlled sanding experience, with less edge warping and a smoother overall surface. If you’re pairing these sheets with a dust extractor or vacuum system, you’ll likely notice a cleaner work area and less clogging during extended sessions.

Construction and Performance

• FITS FESTOOL RTS 400 & MIRKA DEOS – 14-hole, hook & loop, 80 grit film sheets designed to pair with common compact sanders.
• HEAVY-DUTY FILM BACKING – Polyester film lies between the abrasive grain and backing for improved heat dissipation and a stronger overall disc.
• DETERMINED DURABILITY – Polyester film construction helps resist tearing, keeping edges intact around corners and during heavy material removal.
• ANTI-CLOG COATING – Zinc stearate coating sheds dust, helping maintain cutting power when paired with a dust extractor.
• FLATTER, SMOOTHER FINISH – Film backing promotes a flatter disc and steadier finish compared with paper or mesh alternatives.

Why it Works for Your Projects

These sheets are versatile for woodworking, auto body work (including paint removal), drywall work, epoxy smoothing, and finishing painted surfaces. The combination of heat management, edge stability, and anti-clog features supports longer sessions with fewer interruptions, while still delivering a reliable, warp-free finish.

Tips for Best Results

• Pair with a dust extraction system to maximize dust control and tool life.
• Use across a variety of surfaces, from raw wood to finished paints, for material removal or surface refinishing.
• Choose the 14-hole pattern to balance suction with effective material removal for a consistent finish.

Packaging and Value

Sold as a 50-pack box, these sheets offer bulk value for shops and ongoing projects. The combination of durability, dust management, and compatibility can support a steady workflow without frequent sheet changes.
