The Bosch 5-Inch Variable speed random orbit sander keeps you in control while finishing a variety of surfaces. This tool uses a random orbit design that limits vibration and mitigates surface imperfections. It comes with a speed-dial and filtration system that sucks away particles of all sizes. This Bosch random orbit sander even collects the smallest particles, including those smaller than a single micron in size. The storage canister screws into the tool, so you can remove it whenever it needs to be cleared out. The variable speed sander uses a flexible backing pad that can support bumpy and grooved surfaces. Once you decide on the standard 8-hole disc you need for your project, the Hook-Tight system holds everything in place. The grip, located on top of the device, keeps your hand above the center of your working area while the unit rotates and orbits the sanding pad. This process works in conjunction with a unique braking system that prevents swirls and other imperfections when you finish the job.
