Getting ready to drill my fridge door for faucets. Purchased shanks and equip from MoreBeer along with the 25mm hole saw. I've read some people like to use a length of PVC around the shank to protect the door. Do I need it? If so, I am looking at a larger hole saw of course, unless there is thinner walled PVC than Sched 40 out there someplace.
Thanks for the help!
