Assuming I have an indexing table, what is the best way to cut an internal hexagon on a vertical slotter? Should I grind a 120° V cutter and go after the corners, a flat cutter and go after the flats full-width, or a narrower flat cutter and go after about half a flat at a time and traverse to machine the whole flat? This is to make a 1/2"-across-the-flats hex hole in Durabar about 0.7" thick starting from a 0.503" hole, with the end result being the same as I'd get shoving a standard 1/2" hex broach through the hole (but without buying and busting a 1/2" broach for lack of a press with enough headroom).
