You are working with stainless. There is little to no mechanical difference between cold 2b finish 304 ss, and hot mill finish 304 ss. It is not the same thing as carbon steel definitions.
Most any stainless over 3/16 thick will be mill finish.
Stainless (even though not much different than steel structurally) does machine very differently.
So cut speed, drill speed, turning/milling, will all be at roughly half the speed. Or in other word....take double the time and power to do.
So when you are ready to drill a hole.....half the rpm.....double the pressure.....and it will take twice as long.
And yes thin abrasive cut off wheels work well.
