Oh, OK…then ruff stuf carries what you need. If you just need to do a quick, non super precise job. Harbor freight sells a burr bit kit (comes with five or 6 diff bits), and low-grit sanding drums that I have used in the past, for that very purpose.

do they really? I didnt see that, I gotta check that out then.
