The main benefit of using a sander is that it can quickly and easily remove excess material from a piece of wood, resulting in a smoother surface. It can also be used to create a desired shape or texture on a workpiece, such as sanding down edges or rounding over corners. Additionally, sanders can help to reduce the risk of warping by removing any unevenness in the wood's grain. Lastly, sanders can be used to finish off a project by providing an even, smooth surface for paint or varnish.
