I agree with mike. Low RPM and Slow Feed. Most importantly is the low rpm.
Additionally the machine oil reduces heat. 

Remember. Heating and cooling hardens the stainless steel. So when you start
drilling a hole don't stop. It will be much more difficult to complete the
hole. 

A drill press is ideal for this job.
