Which tool is commonly used for finishing surfaces by removing material?

The belt sander is commonly used for finishing surfaces by effectively removing material to create a smooth and uniform finish. It operates by using a continuous loop of sandpaper that is driven by a motor, allowing it to rapidly remove material from wood, metal, or other surfaces. This tool is particularly useful for tasks such as preparing surfaces for painting or creating a polished look on furniture and cabinetry.

In comparison, a drill press is primarily designed for drilling holes and is not intended for surface finishing. A portable saw is used for cutting materials rather than finishing surfaces. A router, while it can shape edges and create designs, is typically used for more intricate work rather than broad surface finishing. Thus, the belt sander stands out as the best tool suited for the specific task of removing material to finish surfaces effectively.
