    Just an idea.

    Maybe turn the final cut to almost full radius, leaving a tiny step, maybe 0.2 mm wide and deep ledge.
    Then plunge in z direction cutting only the ledge, with a suitable different...

    Fantastic thread.

    VFDs are not bad for motors. As such.

    But bad VFD tuning, can wear out or break even a good motor.

    OP:
    I know of nothing that has "tilt" in the chuck.

    Likewise, in a lathe, I cannot see tilt as being desirable.
    (adds axis, aka pwr 2 less rigid).

    To op.
    Try it as I suggested, with a bored starter hole.

    Put a gage pin in it, indicate that.
    Report back.

    I suspect that the hole is very true, and very much on size.

    You can test with...

    Indicating a drill shank is probably not a needed step.

    Yes.

    You would be removing less than 0.01 mm of material, and mostly on an inclined plane.
