What do you need to swap over on the mill? Take the milling cutter out and put a drill bit in? 99% of my drilling is done on the mill, setting out with handwheel or DRO is quicker and more accurate than marking out and locating a punch mark so more than save the time..
It's going to be more rigid and likely squarer than a lot of cheap small bench drill and vari speed to. Even with a bench drill you should be able to get speed down enough to suit a machine reamer which is approx half drill speed.
