The Bosch ROS65VC-5 Random Orbit Sander/Polisher delivers a Vibration Control™ suspension system, which minimizes the amount of vibration that reaches the hands. This rear-handle sander allows for multiple ergonomic soft-grip positions, enabling comfortable two-handed or one-handed operation for superb comfort. This sander includes a powerful 3.3-amp motor with a variable-speed dial to allow the speed to be matched the task and the material. Its pad-dampening system helps prevent swirl marks, and the microcellular hook-and-loop backing pads that can be used to sand flat surfaces and many contoured surfaces. It accepts Bosch 5-in. and 6-in. high-performance sanding pads. Built with a die-cast aluminum gear housing and a dual-bearing pad mount, this unit includes two dust-collection attachments, a microfilter dust canister with integrated paper filter and a hose adapter for connection to a vacuum cleaner hose.
