For finish sanding I use a random orbit sander with 220 grit. I also use it with heavier grits to remove material to bring two uneven pieces to a matched surface level at times. I also have a 1/4 sheet palm sander I use to remove material at times. Between these two they've met my needs so far, but I'm wondering what a hand held belt sander is used for? Does it just do what the 1/4 sheet palm sander does but faster?
