I have a keyway broach set, that goes from 1/2" up to 1-9/16", that was a gift from my wife's uncle.
I also have a powered unit from National Machine Tool company, out of Cincinnati, Ohio. It fits in a drill press, with a rotation rod, much like a tapping head assembly, that has a cutting wheel that is drive by the drill press, that cuts the keyway slot. It has a 3/4" shaft and cuts a 3/16" keyway, somewhat limited, in use. I also have spacers to go up to a 1-1/4" bore, but at that bore size, a 3/16" keyway is usually too small.
below is an internet picture of the type of cutters, I'm talking about
