Still have my original 112. I just bought a new house recently and this weekend I got a new deadbolt for my back door. The hole was a little too small for the new one, and using a hole saw would have just chewed it up
May I make a suggestion for next time? To enlarge a hole with a hole saw, first use the hole saw to drill through a piece of 3/4" material, then clamp that piece over the hole you need to enlarge. That will act as a guide to start your hole saw without using the pilot.
