    Re: Best way to run this part.

    TORNOS Micro 7, Connector (EEM7003) - YouTube

    You can see how they do it at around 1:10.

    Looks like a tapered ID bushing. Maybe made from 440C Stainless or tool steel.

    From the text file, which I believe is the one from WinCNC:

    T0200 X Y Z Q1 H K2 E

    T700 K2

    X.3 = Use X to position X after the tool call.
