What is the difference between ER25 and ER32 collets?
I choose based on tool size- ER25 and 20 are all straight shank holders for small drills, spindle mounted ER32 for larger stuff endmills etc.
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.
How to identify collet type?
The easiest way to determine what type of collet your machine has is to measure the length and diameter of the collet. All collets have a distinctive length and diameter.
