I am working on a project and will have to drill 8 holes in 8-18
stainless steel. The stock is 3/16" thick. I have good equipment ..
drill press, machinist vise, sharp drill bits, etc. The holes will be
13/32" in size.

Shall I drill in one step or start with a pilot hole and enlarge. If
the latter, what drill sizes should I use?

All suggestions appreciated.

Cobalt bits. Don't even think of using HSS.

Start at 1/8" and work up in increments. The fact that
you're using a press will make it much easier.

Also, do not attempt to hold the stock by hand.
