^ I gnore that guy.

Put some masking tape over the area you would like to drill through. Use a drill press. If you don't have one go buy one at Sears or find someone who does, as they're very inexpensive.

Also, use a high quality bit that is the correct size. If you are worried about making the whole in the right place drill a small pilot hole first.

Hope this helps
