A Random Orbital Sander is a power tool used for smoothing surfaces, such as wood or metal. It features a round sanding pad that moves in a random pattern, which helps to prevent swirl marks and achieve a smooth finish. The sander is typically lightweight and easy to handle, making it suitable for both professional and DIY projects. These sanders use interchangeable sanding discs, allowing users to select the appropriate grit for their task. They are commonly used in woodworking, furniture refinishing, and automotive work. The design of a random orbital sander makes it efficient for achieving a polished look without extensive effort.
