I am another happy CDCO customer. The chucks with the two piece jaws are really nice because you can do soft jaws and you don¡¯t have to run the jaws all the way out to flip them around to go from internal to external.? Because I did the chuck with a separate back plate that I finish machine I did not spend the extra money on the adjust true.? If I need high precision I¡¯ve got a four chuck and a adjust thru collet holder, but for general machining are usually just use the three jaw.
