Really? I did not know that. That's kind of how I feel about 5C collets. I've had to grip a very short piece a couple of times in the past, and didn't like it at all. Had to crank the snot out of the nut and even then the parts moved slightly under light cuts. Of course it's probably because my collets are imports.
I've lusted after a ER40 setup for a long time, but now I'm not so sure since I would most likely only use them for short hard to hold pieces.
I hardly ever do multiples of the same part.
