Argh. Buy a bit, they are not expensive. Where are you?

In the US/Canada try KBC tools for micrograin solid carbide bits for
a few dollars each. While you're at it, buy their assortment which
is on page 2 of their current sale flyer. Forget about Home Despot and
such places, they don't carry the right stuff. If you are an incurable
cheapskate, buy high-speed steel, but they will dull after some dozens
of holes in FR4 laminate.

For headers you probably want around 0.9-1mm diameter.
