About Flap Discs

Used with angle grinders, flap discs are made with layered abrasive-covered flaps mounted on a rigid backing that enables grinding and finishing in one step. They provide a smoother, cooler, and more controlled grind than grinding wheels while providing longer life, a more consistent finish, and less buildup than fiber discs. Choose lower grit numbers or coarser grits for an even, smooth finish, and higher grit numbers or finer grits for a fine, polished finish.
