I'm building out a new keggle, and having trouble with the last hole. I want to install 1/2" plumbing through the chime, where the stainless looks to be twice as thick as the regular keg walls. I'm guessing it's around 1/8". I trashed a few speed bits drilling the hole for my punch. Then I broke the draw stud and bent a point on my Greenlee punch. I tried a cheap Harbor Freight punch, but it died instantly. My old step bit made a little progress, but now it's toast as well.
What is my next (economical) option? Will a 7/8" hole saw from big-box work? Do I go for another cheap step bit? Or will I have to spend the money on a more expensive step bit or a new Greenlee punch?
What do people use to get through thicker stainless?
