A Random Orbital Sander is a power tool used for sanding surfaces to achieve a smooth finish. It combines a circular sanding pad that moves in a random orbit, reducing the risk of swirl marks and uneven surfaces. This tool is commonly used in woodworking, furniture refinishing, and automotive work. The sander operates by attaching different grits of sandpaper, allowing users to choose the level of abrasiveness needed for their project. Its lightweight design and ergonomic handle make it easy to maneuver, making it suitable for both professionals and DIY enthusiasts.
