WEN portable grinder allows for detailed sanding of wood, metal, and plastic with access to hard-to-reach places. It can also be used to clean welds and remove rust from parts. It is intended for use with 1/2 x 18-inch sanding belts — especially effective in narrow spaces. To ensure full control over the workpiece, the belt speed can be adjusted — up to 1800 ft/min. The built-in system automatically tracks and tightens the belt. Additionally, the design allows for angle adjustment — with a motion range of 50 degrees. The grinder is equipped with a convenient handle and several control buttons.
