Darren,
A straight tooth milling cutter, or any milling cutter for that matter can be used on a horizontal or vertical milling machine, it just needs to be mounted on an appropriate arbor. The cutter shown might be a good choice to mill a slot in the side of a part that is difficult or too large to fixture any other way than flat on the table. The problem you run into using milling cutters on a vertical mill is rigidity. Since there is no arbor support in the vertical orientation, larger cutters will be more apt to chatter when used on a vertical vs. a horizontal mill. On the other side of the coin, end mills can also be used on a horizontal mill for the same reasons. All you need is an appropriate size tool holder.
