What is the clamping range of a 3C collet?
3C Collets
They are small and they have a limited clamping range. Because of the limited clamping range, they must be used with material that is the nominal diameter of the collet. And since they are only available in 1/16-inch increments, they are not very useful. 3C collets have a size range of 1/16" to 1/2".

What does er stand for in collets?
The standard series are: ER-8, ER-11, ER-16, ER-20, ER-25, ER-32, ER-40, and ER-50. The "ER" name came from an existing "E" collet (which were a letter series of names) which Rego-Fix modified and appended "R" for "Rego-Fix". The series number is the opening diameter of the tapered receptacle, in millimetres.
