Does anyone have any feedback as to which size hole saw to use for adding a weldless kit? I have seen both 7/8 and 13/16 recommended and I am not sure which one to use. Worried about ruining my first brew pot.
Is there any reason you couldn't use a 7/8 or 13/16 drill bit instead of the step bit?
I would not try to drill a hole at 7/8 on a first pass in SS unless you have a drill press, a decent jig to hold the kettle in place, and a lot of patience...
The likely outcome is the bit will overheat as it deforms the SS with pressure applied to the bit.
If you don't want to buy a step bit, start with a pilot hole say 1/8 or so and work your way to 7/8 over several steps.
Never drilled a kettle, but I have a lot of experience with SS...
I have found that the 7/8" hole saw is just a tiny bit too big for the weldless fittings.
