Designed for wood and metal sanding applications. The flexible cloth backing makes it highly adaptable to contoured work pieces, 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 life and high stock removal makes it a truly universal abrasive. Especially well-suited for soft and hard woods, MDF and soft metals such as brass and aluminum. Available only in 5" PSA (sticky-back) backed sanding discs.
