I am interested in drilling approximately 0.2mm diameter micro hole array in ss 304 substrate. Is possible to use commercially available syringe needles made from ss 304 or ss 316 as electrodes for this purpose?

This will make is very easy since making a hollow copper electrode with 0.2 OD and in large numbers is challenging wheres as ss syringe needles are easily available commercially.

Are there any papers on using ss 304 electrode for electrochemical drilling on ss304 substrate?
