The standard sizes are ER-8, ER-11, ER-16, ER-20, ER-25, ER-32, ER-40, ER-50. The "ER" comes from an existent "E" collet which Rego-Fix modified and appended "R" for "Rego-Fix".

ER collets contract over a range of 1mm and are available in 1mm or 0.5mm steps, so a range of ER collets can hold any cylindrical shank, metric or imperial.
