EL Belt sanders are used for fast material removal over large surface areas such as floors, tables and doors. There are 3 types of belt sanders: 3 x 18", 3 x 21" and the Powerfile™. The first two belt sanders are differentiated by the size of the sanding surface they cover. The Powerfile™ has a narrow 13mm sanding belt which is ideal for sanding, shaping, filing, sharpening and rust removal applications.
