Mirka 5" Cloth PSA discs. Targeted towards wood and metal sanding applications. The flexible cloth backing makes it highly adaptable to contoured workpieces and radiuses, thus optimal for profile sanding, seams, edges and other applications where a flexible abrasive with high edge wear is needed. The semi-open coating, fast cut, long lifespan and high stock removal makes a truly universal abrasive. Especially well suited for soft and hard woods, MDF and soft metals such as brass and aluminium. 80 Grit.
