This adaptability makes them an excellent choice for professionals working in industries such as automotive, woodworking, metal fabrication, and more.
Durable Film Backing for Enhanced PerformanceThe robust film backing provides superior tear resistance compared to traditional paper discs. This added durability ensures the discs maintain their integrity and edge retention, even during demanding wet or dry sanding applications. As a result, users benefit from longer disc life and consistent performance.
Optimized for 3M Xtract Random Orbital SandersFor optimal results, pair these discs with 3M Xtract Random Orbital Sanders. This combination maximizes dust extraction, enhances sanding efficiency, and helps create a cleaner work environment, all while delivering a high-quality finish.
3M Hookit System for Clean, Reusable AttachmentThe comprehensive line of 3M Hookit discs is specifically designed for environments where adhesive-backed discs may be compromised by dust or debris. The Hookit system utilizes a convenient hook-and-loop attachment method, allowing discs to be easily attached, removed, and reused throughout their lifespan. This not only improves cost-effectiveness but also streamlines workflow by reducing downtime.
