I failed to hit the answer to this with a search but I'm sure it has
been described.

I have a Sears Craftsman dremel tool I bought some time ago and kept in
storage and never used. It came with a bunch of tools. It seems as
though I've heard of people fashioning simple pc boards by removing
copper from a board leaving pads and traces and such. Can someone
describe the tool they use to do this? And can you describe about how
fine a feature you're able to make this way?

Thanks,
