Flap Wheels are a form of rotating tools that can be used on a grinder. Their name comes from the strips (or flaps) of abrasive material that they have, spreading out from a central hub. The most common method for securing the flaps to the hub is adhesive that bonds the flaps together and to the hub. Tasks that flap wheels are used for include de-nibbing, edge breaking, proper stain application, and sanding. When you use sand with flap wheels instead of doing it manually, you can reduce the time and effort you spend. When you are sanding items that have contours or profiles, these tools are especially useful and effective. Flap wheels are flexible and can be used for fine sanding yet will not leave burns or white lines on an item’s finish. The quality produced when flap wheels are used in sanding is impressive because they are designed to give consistent results.
