I use a Black and Becker hand-held mini-drill. Photo here:

I use both 1.0mm and 0.8mm drills, tungsten carbide, to suit the
components to be fitted. I find that it helps to have a "dot"
of the right size pre-etched into the pads -- check the settings
in your CAD software to get the size right. This acts like a
centre-punch mark, and keeps the bit on target.
