Single point thread tools

To give you a comparison to think about, why do gear hobs have to be offset at an angle from what they're cutting so accurately?

It's an Apples to Oranges comparison because angling the hob relative to the work lets you use one hob for a variety of gear sizes and pitch angles, even racks, it's not relevant to thread milling because Thread Mills are made Inside/Outside specific and for a set pitch and range of Major Diameters, these are all but 3 of mine (the other 3 live in holders by the mill), each is for a specific job -
