The ER collets and the ER collet chucks are designed and made in accordance with ISO 15488:2003(E). Especially the eccentric design of the inside of the collet nut is to help increase the capacity of the collet nut and improve the assembling efficiency of the entire tool kit.
Eccentric Design, ISO 15488:2003(E)The inside of the ER collet nut is intentionally designed like off-centering to help mount the ER collet much easier. It is in accordance with the requirements listed in ISO 15488:2003(E). If it is made symmetrical, the ER collet with the diameter larger than the inside size of the collet nut cannot be installed. | AssembleInsert the ER collet into the nut at an angle.
