Serious Grit 6-Inch 49-Hole 320 Grit Sanding Discs – Heavy-Duty Hook & Loop, Festool 150 Series, 50-Pack

Prepare, refine, and polish surfaces with Serious Grit 6-Inch 49-Hole 320-Grit sanding discs. Engineered for Festool 150 Series random orbital sanders, these discs pair a rugged film backing with a precise hole pattern to help manage dust while you work. The 50-pack provides a steady supply for ongoing projects, from quick touch-ups to longer refinishing sessions.

Key features work together to deliver a consistent experience. The discs are built with a durable polyester film and a long-lasting 60% nylon hook-and-loop backing, so you can reuse discs without chasing frayed edges or pads flying off mid-sand. The heat-treated zinc stearate anti-clog coating sheds dust before it clogs the surface, helping maintain cutting power when used with a vacuum or dust collection system.

In practical use, the film construction helps create a flatter, stronger disc that yields a smoother, swirl-free finish compared with traditional paper or mesh discs. The coating keeps the active abrasive area efficient longer, contributing to steadier results across surfaces like wood, metal, drywall, epoxy, and painted finishes.

Compatibility and versatility

These discs are designed for Festool users, fitting all Festool 150 Series ETS and Rotex sanders with 6" pads, including ETS 150/3 EQ, ETS 150/5 EQ, EC 150/3 EQ, EC 150/5 EQ, and RO 150. The combination of hook-and-loop reliability and anti-clog performance makes them suitable for both prep and finishing tasks.

What you can expect in practice

• Cleaner sanding sessions when paired with a dust extractor, thanks to the anti-clog coating.

Note: Always follow sander manufacturer guidelines and safety practices. The disc is designed to complement, not replace, proper technique and ventilation.
