What is a "belt sander"?

A belt sander is a power tool used for sanding large, flat surfaces. It has a continuous loop of sandpaper that moves rapidly over the surface, quickly removing material. Belt sanders are commonly used in woodworking and construction to smooth rough surfaces, shape wood, or remove old finishes. They are especially useful for large projects, such as sanding down wooden floors, doors, or furniture. Belt sanders come in different sizes and can be adjusted for speed and pressure depending on the task at hand.
