I have no problem getting through the brick, the problem will be cutting a
7" hole in the stainless steel liner that will join to a 7" "fishmouth"
shaped end of more liner.

I noticed that about 30 seconds after I posted my reply... But figured the
same method could be used in the stainless... with a metal cutting bit and
PLENTY of coolant.

You will not be able to drill many holes in stainless without keeping the
bit plenty cool with coolant of some sort. Don't even try...

Anyhow... You could still drill holes in a circular pattern and then use a
small dremel or sawzall-type blade to connect the dots and get a roundish
hole.
