The disc delivers a fast cut rate with a fine scratch pattern to minimize the visible sanding marks for a finish with an improved look. E-weight paper backing delivers a strong base that resists tearing. Minimize loading and dust without sacrificing an aggressive cut with the open coat and antistatic design. Ideal for fast cuts on hard wood edger jobs, this medium grit belt features a hook-and-loop back to make disc mounting and changes easier.
