I regularly use 0.2mm drills and sometimes even down to 0.1 - and that's carbide drills drilling tool steel usually... Have you looked at the price of 0.2mm carbide drills recently?? Fortunately, I can often get hold of a few 0.3mm and above drills ex. the printed circuit industry but they are getting harder to find recently and anything smaller than that is usually special order...
