James,

 

I'm not sure what the part looks like.  Are you drilling across the cylinder
or centered on the end of it?  If drilling across use a V-block in a drill
press.  Soluble oil is probably the recommended cutting oil but some other
light oil or even lard could work if you only have a few holes.  The lube
will help the chips clear and also cools the bit.   An .030 without a drill
press will be a challenge.  In this case don't force the drill, clear out
the chips and lube often and watch so the bit doesn't get side pressure.
