Flap Discs
Abrasive Flap Discs
Flap discs are made of overlapping sandpaper "flaps" used to remove only small amounts of material and leave a smooth finish. They are mainly used with grinders. Flap discs come in various densities meaning the flaps can either be layered tighter or farther apart. Depending on your project you can choose from a selection of coarse to fine grit sizes.
