Belt sanders may be handheld and moved over the material, or stationary, where the material is moved to the sanding belt. Belt sanders can have a very aggressive action on wood and are normally used only for the beginning stages of the sanding process, or used to rapidly remove material. Belt sanders were one of the first power tools used in the growing field of power tool drag racing wherein a pair of stock or modified belt sanders are placed in parallel wooden channels and fitted with long extension cords.
