An orbital sander is a power tool used for smoothing surfaces, typically wood, by using a circular sanding pad that moves in an orbital motion. This motion helps to reduce swirl marks and provides a finer finish compared to other types of sanders. Orbital sanders are commonly used in woodworking, furniture refinishing, and home improvement projects. These tools come in various sizes and can be powered by electricity or batteries. They often feature a dust collection system to minimize mess and improve visibility while working. Sandpaper discs, which are available in different grits, can be easily attached and replaced for various sanding tasks.
