Serious Grit 6-Inch 49-Hole 40 Grit Sanding Discs – Heavy-Duty Hook & Loop Film, 25 Pack

Built for Festool Sander Power and Real-World Projects

Meet Serious Grit’s 6-inch, 49-hole 40-grit sanding discs, engineered for aggressive material removal while keeping a steady, controlled feel on your Festool 150 Series random orbital sanders. The combination of a durable film layer and a robust hook-and-loop backing delivers dependable performance from the first pass to the final pass on a range of materials. While you’re tackling wood grain, metal highlights, drywall texture, epoxy coats, or painted surfaces, these discs stay true to form, helping you move through tasks with fewer interruptions.

What makes these discs stand out is how they’re built to last. A tough polyester film backs the abrasive grain, reducing edge fray and tear around corners. The backing is reinforced with a long-lasting 60% nylon hook-and-loop system, designed to stay attached and minimize disc popping off the sander mid-work. An anti-clog coating, treated with heat-dissipating zinc stearate, sheds dust before it can clog the surface, letting you maintain cutting power longer when paired with a vacuum or dust collection system.

Performance You Can Feel in Every Job

The film-backed abrasive creates a flatter, stronger disc that helps generate a more uniform finish compared with traditional paper or mesh discs. The anti-clog coating preserves more of the disc’s effective area, which sustains cutting power and helps you achieve consistent, swirl-free results. This versatility makes the discs suitable for auto body work, including paint removal and wet sanding, as well as general surface preparation for wood, metal, drywall, and composites.

Why This 25-Pack Makes Sense

• FITS FESTOOL SANDERS – 6-inch, 49-hole discs compatible with all Festool 150 Series ETS and Rotex sanders, including ETS 150/3 EQ, ETS 150/5 EQ, ETS EC 150/3 EQ, ETS EC 150/5 EQ, and RO 150.
• MORE DURABLE & REUSABLE – Durable polyester film backing and a 60% nylon hook & loop system enable multiple uses with consistent performance, reducing the need for frequent disc changes.
• LESS CLOGGING – Heat-treated zinc stearate coating sheds dust, helping the disc stay effective longer when paired with dust collection.
• SMOOTHER FINISH – A flatter film construction and efficient heat dissipation contribute to a steadier, swirl-free finish on varied surfaces.
• WET/DRY COMPATIBILITY – The film discs perform well in wet or dry conditions, making them versatile for auto body work or moisture-prone projects.

What You Might Notice in Real Projects

Users often report fewer interruptions to switch discs, thanks to the robust backing, and a clearer path to a smoother final surface. The 40-grit grade balances aggressive material removal with controllable finish, enabling you to shape contours, knock down coatings, or profile edges with confidence. The 25-pack format provides a ready-to-work supply so you can keep projects moving without waiting for restocks.
