The Bosch ROS20VSC 5 In. Random Orbit Sander/Polisher delivers fast removal and a well-blended, ultra-smooth finish, so woodworkers and finish carpenters can sand quickly and to exacting standards. It is designed to eliminate swirl marks on the workpiece, thanks to an integral pad dampening braking system. Bosch"™s hook-and-loop disc attachment ensure firm grip of the disc during use. Additionally, the microcellular backing pad is pliable to ensure a smooth, fine finish on both flat and contoured surfaces alike. With a comfortable soft-grip top and body design, this tool has variable-speed control from between 7,500 and 12,000 OPM to match the speed to the task. It also includes an on-board system for filtering fine dust.
