A belt sander is a power tool used for sanding surfaces, typically made of wood. It consists of a continuous loop of sandpaper, known as a belt, that rotates around two drums. This tool is effective for quickly removing material and smoothing rough surfaces, making it popular in woodworking and construction. Belt sanders come in various sizes and can be handheld or stationary. They are often used for tasks like preparing wood for finishing or shaping furniture. Safety precautions, such as wearing goggles and a dust mask, are important when using a belt sander to protect against dust and debris.
