This 18V Random-Orbit Sander features a well-balanced ergonomic palm grip, which allows your hand to be closest to the work material to avoid tilting and pressing down, for best results. The easy-to-reach on/off switch offers intuitive operation. It has a vibration-dampening element to help minimize user fatigue. The Bosch GEX18V-5 Brushless 5" Random-Orbit Sander has a powerful 18V brushless motor that delivers similar stock removal to a corded sander. The speed selector delivers the best results in different materials and applications. The sander has a 5", eight-hole sanding pad, which provides optimal dust collection when the sander is attached to a vacuum or a dust bag. The dust pad is ideal for flat, concave and convex surfaces. The included dust bag allows mobile dust collection, while the tool has an interface for vacuum-hose attachment. The sander has a compact shape with close-to-the-workpiece design for control in hard-to-reach areas. It also has soft-start technology, constant speed and a hook-and-loop backing pad.
