I remember meeting that problem in the past.

I punched the center of the part and set it on the faceplate of my lathe, checking it was not off-center. Tricky with the four sliding fixations.
I drilled a hole big enough to give room to a cutting tool and brought the hole to the right dimension.

Of course there must be other ways to do it. Once I used acetylen first, then the lathe.
