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 more even finish compared to other types of sanders. Orbital sanders are commonly used in woodworking, furniture refinishing, and home improvement projects. These sanders come in various sizes and can be powered by electricity or batteries. They use different grits of sandpaper, allowing users to choose the right level of abrasiveness for their specific task. Dust collection systems are often integrated to keep the work area clean while sanding.
