Sharp carbide drills. The proper speed is as fast as you can ;-) 30 or
even 50k RPM would be nice, the slower the RPM the slower the feed
should be. The drills must be sharp or the RPMs won't do no good.

In the past, I used 2 pass drill to drill the hole, the 2nd pass, one 1 mill smaller but it doesn't seem to help much. I can increase the diameter of the via hole up to 50 mils.
