Belt sanders work by revolving a sandpaper belt around two tensioned drums. They can be either handheld or table mounted.
Belt sanders are great for removing large amounts of material quickly, but they should always be used with the grain of the wood and can easily gouge the work if you aren’t careful.
Due to their shape, belt sanders aren’t able to sand into corners or flush against walls and other obstructions.
Sandpaper: Belt sanders require special cloth sanding belts in the proper size.
