Ed,
If you have parting off tool you could use that, start in the middle and work out. It might just have enough clearance to do it.

Ed,
I thought you had bought some indexable boring bars?

Ed,
Just plunge the boring tool in near the outer dia and move the tool towards the centre. A few thou at a time.
Now what am I missing here

Probably nothing. I was just looking for advise on ways of getting the job done.

Since dallen is flaunting his tiny boring bar, I may as well jump in with a pic of one of my smallish end mills. It's a .005" diameter carbide end mill that I used to mill a .012" square pinhole in a piece of brass for an optical application. Those are .010" graduations on the scale.

In certain company, flaunting smallness is not a good thing.
