I have made spools and others for many years by using a cordless drill and holding a triangular file against a brass pin. It will not bounce out or be dangerous unless you put too much pressure in the file. Relax and let the tool do the work. Be a craftsman and not a bludgerer.
One paranoid customer wanted drill resistant locks but without buying new and better locks. I made him some top and bottom pins from #32 (.116) high speed drill bits. I hald them in my cordless drill and turned them against a fine grit belt sander. They worked great.
Nothing is foolproof to a talented fool. Wisdom is not just in determining how to do something, but also includes determining whether it should be done at all.
