So I just recieved my first cnc mill. It is a tree journeyman 425 that uses cat 40 tooling. as I have only used the manual R8 collets before I am totally in the dark. Where do I find used tool holders and what do i need. It seems like I can get one end mill holder that fits multiple sleeves for the different sized end mills. what do I need for a drill chuck? what about running taps?
