The "ER" collet system, developed and patented by Rego-Fix in 1973, is the most widely used clamping system in the world.ER collets are now available from dozens of companies worldwide. The standard sizes are ER-8, ER-11, ER-16, ER-20, ER-25, ER-32, ER-40.

The number is the cavity opening diameter in millimetres, the outside collet diameter. 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 circular shank, metric or imperial. ER collets may also be used on a lathe to hold work pieces.
