Worked as intended

Just what I needed to increase the ID of some 1" black pipe where the bore was deformed by heat during welding. The problem with this counterbore is the 3/4" shank, which requires a JT4 drill chuck. I found an adapter that goes from 1/2" straight shank to JT4, but it was a one-time thing that looks pretty goofy attached to a hand drill. Delivery took longer than expected.
