I have a tap that has a 7/16" square butt on it. I am wondering if there is an adapter that I can get for it that will allow me to fit it into my 8" drill press. It is just a hair too big to fit into the chuck. Don't worry I know how to tap, I will only be using the drill press to keep it perfectly straight, while I will manually spin the chuck with my hand for the tapping. Any ideas?
