Being the newbie that I am to milling. I had seen several mills that sport a drill chuck and I had at one time thought that I could convert a drill press to a milling machine(i,m kinda givin that idea up). And someone said that the chucks were not made for milling. So my question is these collets which I assume are the mill holders, I can,t tell how you tighten down the mill cutter. With a drill chuck it make sense but the collets, I can see that they clamp around the mill cutter but I can,t tell how they get clamped down. Any one care to educate me on this?
