A flap wheel is a versatile abrasive tool designed for use with angle grinders, bench grinders, and die grinders. It consists of multiple overlapping layers (flaps) of abrasive cloth or paper attached radially to a central hub or mandrel. As the wheel rotates, the flaps wear down progressively, exposing fresh abrasive grains, which ensures consistent finishing and a longer lifespan compared to traditional grinding discs. Flap wheels are ideal for surface blending, deburring, cleaning, polishing, and finishing on metals, wood, and plastics. They offer a softer action than rigid wheels, reducing the risk of gouging or overheating the workpiece.
