What is the best way to bore a 1-1/4” dia hole all the way through a 3” cube of 6160. The hole once bored will have a second hole on top 1-1/2” dia and 1” down. Best using 3 axis or 4th axis with a rotary table. I ask this whether I should be considering purchasing a 3 or 4 axis mill. The cube will require other machining operations like face milling and edges round over as well and 12 6mm tapped holes.
