There is no external system that can do this without distortion. This is a machine application and matter of good machine practices. Meaning, if you select the right drill and speed, you should be able to accomplish task in the drilling operation itself. Not being that familiar with the exact procedure, you may have to drill an undersized hole and then ream with larger.

What kind of polishing are you looking to do? If you're looking for a mirror finish you'll need a pencil grinder with blue stones and cotton buffing wheel attachments with white rouge [affil. link to info/product on Amazon] followed with blue rouge.
