That is a side and face cutter for a horizontal milling machine. Is that what you are asking about?

Or are you referring to an "end mill" for a vertical milling machine, which can also cut from the side or end (face)?

I think horizontal mills can take much heavier cuts than a vertical mill in most cases.
