How many of you have sets of metric drill bits, do you find you use them on a regular basis, and where did you get them? The reason I asked is that when I got a new DRO for the mill of course all the fasteners are metric. Being somewhat stuck in fractional measurements I don't have many metric drill bits. I have all the fractionals up to 1 1/2" and the letters and numbers, but never found much of a need for a metric set. Metric fasteners aren't new to me. In fact I have several sets of metric taps & dies. However even the metric taps I have call out fractional hole sizes.

I've looked at Enco,and all the the "discount" tool houses and none seem to have very much to offer. About the most complete sets I've seen are at MSC, and they seem a bit pricey. So the question remains is it worth it to buy a set of metric bits? For general purposes it seems there are fractional, letter and number drills within .0001 or so of the most popular metric sizes. Is it finally time to move into the 21st century?
