I just stick it in the boring head where the boring bar would go. Mine takes 1/2" shank. I currently have a 1/2" 3 flute end mill in it. The end mill in it right now is a lucky find - it has a weldon flat, that when tightened in the boring head, makes one of the flutes radial. I think I was last cutting 0.749 bearing seats with it. Old end mills make great boring bars. Just grind off whatever is in the way...
