ARC ABRASIVES Adhesive-Backed Sanding Disc

General purpose sanding discs optimized for use on all metals have a closed-coat aluminum oxide abrasive applied to a paper backing. Aluminum oxide is a strong, sharp, and durable abrasive that penetrates the work surface and withstands heat and high speeds. Closed-coat abrasives have abrasive grain across the entire surface to provide a smoother finish and faster material removal than open-coat coverage. The paper backing provides a smooth, flat surface to provide consistent pressure across the work surface. Example metals include mild and carbon steel, cast iron, cobalt, titanium, and chrome.
