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.

What is the difference between ER and SK collets?
After doing some research, it seems that sk collets are better in just about every way. The taper is half the angle of er which results in lower runout, better grip, higher rigidity.
What is the difference between ER and TG collets?
