Guess I will have to go with one of the hole saws or jigsaw blade.
Thanks to all.


If you're going to enlarge existing holes the hole saw will not work unless you put something in the hole to guide and steady the pilot.

Jig saw and file are probably better suited if you have existing holes to enlarge.
