A belt sander is a power tool used for smoothing and shaping wood and other materials. It features a continuous loop of sandpaper, called a belt, that moves rapidly over the surface of the material. This tool is commonly used in woodworking to remove material quickly and efficiently, making it ideal for large, flat surfaces. Belt sanders come in various sizes and can be handheld or stationary. They are often used in conjunction with other tools, such as orbital sanders and table saws, to achieve a polished finish. Proper safety precautions, including wearing safety goggles and a dust mask, are essential when using a belt sander.
