I was thinking, maybe ferrules or rivets might be a source for small
diameter tubing.
Getting the epoxy in there should not be too difficult, i hope ;-)

but then, i don't break so many, if i make no mistake. And if i make a
mistake it will probably still break.
Let us know if you try it and notice they don't break.

I know a electronics distributor here sold "spade" carbide bits that were
very short. I bet those are harder to break.
