I used to use an offset boring head, but after a couple years I got (extremely) lazy, especially because switching to the boring head required me to drop the knee of the mill 3" or so. Now we use positive bearing retention everywhere and 1.125" holes.
My method is to drill with a 1/2" drill first (largest one we have), then go in with a 3/4" then 1" endmill. After that I finish up the hole with a 1.125" endmill. This gets some tight slip fits and a very round hole.
My dream is to own a 1.124" reamer, but the $200 cost for a custom one doesn't suit me too well.
Given that we use a manual mill anyway, it doesn't hurt to use the 1.125" endmill we already own.
