The Norton Red Heat 5" 60 Grit sanding discs are designed for professional hardwood floor sanding and refinishing. These hook-and-loop (H&L) discs feature a ceramic alumina grain that delivers aggressive cutting performance while maintaining a sharp surface for faster material removal and a smooth, consistent scratch pattern. Ideal for mid-cut sanding stages, they help blend edges and refine scratches between coarser and finer grits.
