No. 80 bits - good source?

As Wayne told,
buy this tiny drill bits per dozen or more. They are prone to break because of their tininess. And clamp them into the drill chuck only at the exreme end. They are long, but they also can flexing better and not breaking.

And wear eye protection when drilling.

Lutz, thanks for the tip on leaving them long. That makes sense. I chuck them short and break them often. Price paid doesn't seem to make them last any longer.
