Thanks guys.

Eddy, I used a 3mm radius one of these:

They're really useful tools - I use mine a fair bit. You program it as a 1.5mm tool (tip diameter), touch off the tip and plunge it to a depth of 3mm - in reality you might want to leave it just shy of 3mm, too deep is less forgiving than a tiny bit too shallow...
