* Zirconia Alumina is recognized by its blue color * A rugged synthetic abrasive that is best suited to stock removal applications * The heavy duty structure requires heavier pressure to break down the self sharpening grains * It is ideal for heavy grinding on ferrous and non-ferrous metals and planing hard woods * Recomended for stainless steel aplication * This abrasive can last up to 5 times longer than aluminum oxide on tough applications * Available in grits 24 through 120 *
