Hey, Apprentice, there is one other thing that is hard to find out about until you run afoul of, but is vital in using an ER collet. Never, ever, put an over-sized piece into the chuck. Even .001 oversize will cause several problems that you will have to experience to believe! The worst is that the collet can 'weld' to the work if it is really soft like cast aluminum or soft brass. You can spend hours separating them!
