You probably remember the days in your childhood when your father made you sand your Pinewood Derby car until it was "as smooth as a baby's bottom," and then some. Finish sanding can be a lot of hard work, and at times it may seem like the work is never finished. There will always be one spot that wants to stay rough, or your hands will simply get tired of the repetitive motion. Luckily, the world of power tools has a solution known as the electric palm sander, or finishing sander.
Palm sanders are smaller power tools that allow you to finish sand large projects in a fraction of the time it would take by hand. You can attach regular sandpaper to the rectangular pad on the bottom of the sander. This is nice because it doesn't require any special type of sanding material and you can snap in a new sheet easily by hand. Most palm sanders will have holes in the bottom that act as a vacuum to remove the dust as you are sanding. If you are choosing between a cheaper sander without this option and a more expensive sander with this option, you might want to consult some palm sander reviews to make this choice; the vacuum and collection option makes clean-up a million times easier and also keeps your air safe for breathing. In this case, the extra cost is worth every penny.
