I have some 150+ quick change tool holders and a chuck. The chuck has some issues such as the internal threads that hold it into the quill are partially stripped and I don't know what to do to not make them worse. I bought them used and didn't inspect it as I should have. The threads in the chuck are 7/16 - 20 R8. I paid $400 including shipping for all of them so I don't know what they are worth with the chuck like it is. I've tried to find a name but couldn't. I've found a size on the tool holder like (T 302B) & (T 302C) but no name anywhere thinking I could get a new chuck. It is spring loaded and once the tool holder is put in place you push a button that closes it in place. Really nice if you know what you're doing and I didn't. I have another mill and am using ER40 collets so I am just going to use them on both mills and want to sell these. I would appreciated any kind of help I can get.
I tried to upload some pictures but not sure how they will turn out.
