I have the need to put multiple 3mm holes in steel and stainless steel tubular like parts. Ordinarily, drilling and reaming would suffice but the bore is precision ground so I can't damage that surface and since a piston of sorts slides in the bore, no burr or displaced metal is acceptable in the bore. The actual concentricity, tolerence and finish quality of the hole being made is not critical, only the transition at the bore.
This is a hobby prototyping project, not production related. Would one on the various DIY EDM methods or machines suffice in accomplishing this? Looking for suggestions. TIA.
