Any suggestions?

You can get PCB drills that have a 3.2mm shank for a dremmel, and then
narrow down to sub-mm tips, quite brittle though ...

e.g http://www.ebay.co.uk/bhp/pcb-drill

The carbide ones aren't suitable for use in a hand drill. You could
certainly at one time buy 'ordinary' ones which were - Maplin used to sell
them. But went blunt pretty quickly.

Other way is a pin drill - come with a selection of small drills inside
the body. (they are a thing you twiddle by hand, so not a vast price_
