Flap discs are one of the most versatile grinding and finishing abrasives for applications ranging from heavy stock removal to surface blending and finishing. Flaps discs have three components a backing plate, adhesive and coated abrasive cloth flaps. Small coated abrasive rectangles are concentrically placed on the backing and glued in place, overlapping each other to form a layered abrasive disc. Designed for use on right angle grinders, flap discs can grind, blend and finish in one operation which can often replace the traditional two step process of grinding with a type 27 grinding wheel then finishing with a resin fiber disc. Flap discs by their design, are easier to control, are cooler cutting and offer faster removal with more consistent finishes versus type 27 grinding wheels that vibrate more, are louder and contribute to operator fatigue. Compared to fiber discs, flap discs can last up to 20X longer or more and have a self-sharpening action from the multi-layered flaps. Additional benefits of flap discs are that they do not require a back-up pad and are not impacted by humidity making them easier to store and more reliable to use.
