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.

Angled for aggressive material removal, these Type 29 discs are coated with ceramic abrasive, which is tough, stays cooler, requires less pressure, and lasts longer on hard materials than long-life zirconia alumina and is suitable for use on stainless steel and other hard metals. The angled face of a Type 29 disc makes more contact with the workpiece surface than flat (Type 27) discs for more material removal, especially on contoured surfaces.
