Hi Piers,
When I print my boards I make sure that there is a small etched dot inside each copper pad. Kicad does that automatically (it has an option when printing).
I use a dremel-like tool, rest the drill against the small hole then turn on the drill, and it goes right in the middle. No need to adjust it after it's on.

Having drilled my first few boards with a cordless handyman-type drill, the 20+ year old dremel I now use is luxury. I rest the tip against the hole (lit from behind) then drag it to the centre then push.
