JohnB: exactly right on the grip range. Go watch youtube video from Joe Pi - he covers collet grip issues, and explains it very well.
BTW, for the original poster of this topic: If you have 20 3c collets, you may be close to having a full set. I rarely see a lathe with more than 15-20.
Number of collets to cover a given range is dependent on the grip range of the collet.
5C do not have a very wide range.
I think the ER series has a wider grip range per collet than the 5C.
They go from 2 or 3mm up to 26, I rhink

how many sizes are there on the er40? I like the 5c cause there are 72 sizes. Do you also have a collet block for the er40?
