I forgot to add that I was not tapping under power. Should have used a centre with the tap wrench instead. Totally forgotten about the centre which I used the previous time.
For the first hole, it went in ok till the last bit. I realized that I don't have any feel when tapping with such small tap. The spring loaded centre is a great idea. But I've to make it first... always have problem finding the right size spring.
The drill that was recommended is 1.6mm. How big should I go? 1.8mm? I'll try to get the suggested spiral flute tape tomorrow.

For an M2 x 0.4 thread the recommended drill is 1.6mm.
For an M2 x 0.25 thread the recommended drill is 1.75mm.
Hope that helps.
