TCT hole saws are easy to use,  durable in stainless steel, and provide accurate holes.  Bi-metal hole saws are economical, but they are unable to drill in stainless steel as well and the holes can’t be accurate and perfect. Knock-out punches are good in stainless steel, but they require a lot of time for preparing to punch the hole.
