Drilling Ø0.2mm holes on aluminium

[magicniner]

I am a complete novice but cannot see how else you would do this as most chucks are not going to hold 0.2mm accurately enough.

At the required speeds much of the available equipment has adequate provision for accurate tool holding, I've drilled 0.3mm holes in 316L with carbide drills, I used the supplied chuck on ajapanese X7 speed increaser, peck drilling at 28800rpm with WD40 for lubrication.
You're more likely to break small drills by running them too slow than anything else.
