I needed to enlarge a previously drilled hole. Since I couldn’t use my hole saw’s pilot bit to center the hole, and I didn't have my drill press with me, I had to come up with a solution. What worked for me was to connect two hole saws together. One was the size of the existing hole. This saw "guided" the other hole saw that was the size of the hole I needed to drill.
