Serious Grit - 3.5-Inch (90mm) 120 Grit Sanding Discs - Advanced Ceramic Grain - Universal Multi-Hole Design Fits Festool RO 90 & Other 3.5 in RO Sanders - Heavy-Duty Hook & Loop Film Discs - 50 Pack

Serious Grit 3.5" (90mm) ceramic sanding discs deliver fast, clean, and consistent performance for pros working with wood, metal, paint, or filler. Designed to fit the Festool RO90 and any 90mm random orbital sander, these discs make your sanding easier and more efficient. The advanced ceramic abrasive cuts more than 40%+ faster and lasts longer than traditional abrasives, helping you get through tough jobs with fewer disc changes. The universal multi-hole pattern works with any 3.5" hook and loop sander and doesn't require alignment—just stick it on and start sanding. It pulls dust through your pad for a cleaner surface and better finish. A tear-resistant film backing keeps the disc flatter for more even sanding, especially on edges and corners, and holds up under both wet and dry conditions. The hook and loop attachment locks in tight while you work and removes cleanly when you’re ready to switch grits. If you want a disc that fits right, cuts fast, and holds up through real-world use, this is it.

• FITS FESTOOL RO 90 - Universal laser-cut multi-hole pattern fits Festool RO90 Rotex sanders and any other random orbital sander with a 3.5" / 90mm hook & loop backing pad. No need to line up holes, just slap it on and start working.
• VIRTUALLY DUST-FREE - Laser-cut precision hole layout allows consistent airflow through the disc, pulling dust away from the surface and into your dust extractor. Helps reduce clogging, resists heat-buildup, and leaves you with a cleaner work environment.
• ADVANCED CERAMIC GRAIN - Engineered to cut over 40% faster and last longer than traditional abrasives. Ideal for sanding wood, leveling filler, prepping primer, and scuffing paint across woodworking, metal, and autobody applications.
• DURABLE FILM-BACKING - Stronger and flatter than traditional paper-backed discs, polyester film discs resist edge tear-out and maintains better surface contact for smoother, more even results - especially when sanding sharp corners, edges, or rough uneven surfaces.
• WET/DRY COMPATIBLE - Film backing stands up to water, solvents, and extended use. Perfect for dry sanding or wet sanding applications where clog-resistance and control are critical.
