    I know nothing about diamonds, but am quite familiar with machining
    interference or shrink fits. For an item that size a proper fit for
    a light interference fit is with the part going into the hole being
    about .00025" larger than the hole. This is for metal into metal. It
    is no wonder that your diamond is breaking. A .004" interference is
    suitable for holding a 8" - 12" or so piece into a hole or for
    holding a 2" - 2.5" piece almost as strongly as if it was a single
    piece. 

    I think the proper answer is that you need to cut a seat into the Ti
    and do it as a proper flush set.
