The 19-38 combo brush/drum sander, made by SuperMax Tools, increases a wood shop’s versatility by performing drum sanding, profile sanding, and wire brushing all on one machine. The sanding head speed is controlled by an AC inverter which allows for the faster head speed required for drum sanding, and the slow head speed required for proper brush sanding. Choose from a variety of changeable heads. (888) 454-3401, SuperMaxTools.com.
