When it comes to dialing in an ER system’s performance to match a specific application’s requirements or long life, there are three components to consider: the collet, the body of the holder and the nut.
ER nuts are basic nuts with surface treatment for friction reduction. They have slots on the outside diameter and use a spanner wrench for nut tightening.
NEW BABY COLLET is a series of collets that are world-renowned for their unmatched accuracy and precision. They are the world's first etched with a AA grade that guarantees their excellent runout accuracy.
