How To Counter Bore?

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,
Just plunge the boring tool in near the outer dia and move the tool towards the centre. A few thou at a time.

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. Yikes Yikes
