      Yes, it sure depends on the type of work one does. And, I do some larger
      as well as some smaller parts. This chuck has removable top jaws with fairly
      serrations, but they actually haven't gotten in my way once, yet. I could get
      other top jaws, if I needed them, but I haven't found such a need.

      I still DO have my well-worn 6", and there was something I was doing that
      me to go back. I think it was holding a 1.5" or so tube from the inside. The
      chuck won't take anything that small on the smallest inside jaw step. But, the
      3-jaw is not terribly accurate, and there is some taper on the jaws. I
      reground the
      inside of the jaws, but haven't gotten around to the outside faces of the jaws.
