Serious Grit 5-Inch 9-Hole 320 Grit Sanding Discs | Heavy-Duty Hook & Loop Film, 50-Pack

Powerful, Reliable Sanding for a Variety of Surfaces

Meet Serious Grit’s 5-inch, 9-hole sanding discs in a robust 320 grit. Engineered to pair with Festool’s popular 125-series random orbital sanders, these discs are built to handle wood, metal, drywall, epoxy, and painted surfaces with consistent results. The combination of a film base and a resin-bonded abrasive delivers steady performance from start to finish, helping you move from rough work to a smoother finish without frequent disc changes.

In the real world, the right disc can make a noticeable difference in both feel and outcome. The 320 grit grade offers a balanced rate of material removal while still leaving a finer surface ready for finishing. This set is designed for serious projects that demand durability and predictable results over time, rather than short-lived, disposable performance.

Durability, Precision, and Cleaner Sanding

What sets these discs apart is a triple-layer approach to longevity and consistency. First, a heavy-duty polyester film backing sits between the abrasive grains and the hook-and-loop layer, providing stiffness and heat dissipation that helps maintain a flat sanding surface. Second, the backing uses a long-lasting nylon hook and loop system that resists tearing and keeps the disc securely attached during operation. Third, an anti-clog coating on the disc surface sheds dust before it can clog the pores, helping the disc stay effective longer when paired with a vacuum or dust collection system.

• Durable polymer film backing improves heat dissipation for steadier performance.
• Strong nylon hook-and-loop backing supports repeated use without edge fraying.
• Anti-clog coating reduces dust build-up for more consistent cutting.
• Flat, film-based construction yields a smoother finish compared with paper or mesh discs.

Versatile and Ready for Real-World Use

These discs are designed with practical applications in mind. They perform well for prep work and finishing across a range of materials, and they’re suitable for auto body tasks, including paint removal and wet sanding, thanks to their film-backed construction and heat management properties. The 50-pack box is a convenient bulk option for workshops that tackle multiple projects or maintain a steady supply for ongoing use.

• Compatible with Festool 125 Series sanders for seamless switching between discs.
• Ideal for wood, metal, drywall, epoxy, and painted surfaces with a balanced removal and finish.
• Durable backing and anti-clog coating extend life and reduce downtime.
• Great for both dry and wet sanding workflows, including auto body prep.
