It's possible you could use an annular cutter or a hole saw if you were willing to live with a loose bearing fit. The annular cutter is probably going to do a better job. You could also buy an end mill in the size you want, which would do a pretty good job. That would run you about 60 bucks for a 1.125".

I've always known we had boring tools for the mill, but have only ever used a boring bar in the lathe. Is the procedure to set the boring bar to the appropriate radius above the part, and then cut, or to somehow adjust it while in the part? I ask because on the lathe, I often adjust the radius of the cut while inside the part (so long as the part isn't too thick).
