Specifically developed to achieve outstanding results on the most challenging surface conditioning and repair applications, Abranet HD is the choice where conventional abrasives fail. The Nylon mesh backing material creates a more even abrasive surface which produces a more consistent surface finish more quickly. Designed for optimum performance in wet and dry modes, it features exceptional resistance to edge wear and clogging which means it retains its high efficiency sanding properties for far longer, especially in demanding situations. It's also manufactured using an environmentally friendly, solvent-free coating.
