Durable sanding discs: Made with polyester film construction, these discs are nearly impossible to tear and have a long-lasting 60% nylon hook & loop backing for reuse. Reduced clogging: Proprietary heat-treated zinc stearate anti-clog coating sheds dust before it can clog the disc, making it virtually dust-free when used with a vacuum or dust collection system. Improved finish: Film construction creates a flatter, stronger disc that produces a better finish compared to paper, mesh, or net sanding discs. Anti-clog coating maintains effective surface area longer, enhancing cutting power and providing a swirl-free finish. Heavy-duty polyester film backing: Stronger disc with better heat dissipation and a smoother finish. Ideal for auto body work, including paint removal and wet sanding. Compatibility: Designed for 3M, Bosch, Makita, and Mirka 6-inch random orbital sanders with 15-hole hook & loop sanding discs. Suitable for sanding various surfaces such as wood, metal, drywall, epoxy, and painted surfaces. Serious Grit 6-Inch 15-Hole hook & loop sanding discs are premium film-backed discs designed to fit 3M, Bosch, Makita and Mirka 6" random orbital sanders. Each box includes 50 discs of 120 grit. Our 15-hole hook & loop sanding discs use a proprietary anti-clog zinc stearate coating that sheds dust before it has a chance to clog up your disc, making the sandpaper dust-free when paired with a vacuum or dust collection system. These heavy-duty, fine grit sanding discs offer a long-lasting and consistent finish. Our 120 grit sanding discs are made with heat-treated aluminum oxide with fused zirconia alumina that is self-sharpening, leading to an even finish throughout the long life of the disc. Our sandpaper uses polyester film construction, which is more durable than the more common paper-backed discs. These 15-hole sanding discs are ideal for sanding all surfaces, including wood, metal, drywall, epoxy, and painted surfaces.
