Ron,
The "rated" diameters you are getting are confusing to many due to the fact that it's a "lead angle face mill". Don't be embarrassed because it's complicated and I understand it only because I've been around it for far too long.
The catalog illustrations will show a "Dc" and a "Da" dimensions, and they relate to the nomenclature as well as the physical dimensions. The cutter you list as F4080.B16.050.Z04.03 is as follows:
F4080.B16.050.Z04.03 the "F4080" just describes the cutter model number and generation. The higher the first number, the newer the design.
F4080.B16.050.Z04.03 the "B16" is B meaning cylindrical bore of 16mm.
F4080.B16.050.Z04.03 the "050" represents the "Da" or overall diameter, out to the tips of the inserts.
F4080.B16.050.Z04.03 the "Z04" represents the number of "teeth" or in the case of an insert cutter, number insert pockets.
F4080.B16.050.Z04.03 the "03" represents maximum depth of cut per pass.
There is a variation in certain cutters where after the diameter they may put the letters "DC", and that shows the cutters true cutting diameter maximum flat width. Without the DC it's overall. So from the catalog illustrations your cutter does have a Dc of 42mm.
I have used up to 4" cutters on my old (no longer extant) 1HP Bridgeport milling machine. It was definitely too much for anything more than light finish passes of perhaps .010" (0,25mm) depth in most materials. You could safely use a 63mm F4080, which would have a 58mm Dc, or even an F4080.B22.063DC.Z06.03 which would have a major OD of 71mm but true cutting diameter of 63mm. Bigger than that would really be taxing your machine, and even that size isn't going to be "fully utilized."
Going to a cutter that uses the more common ODMT/ODHT 0605 has the benefit of finding more inserts on eBay, but you can't really use the increased depth of cut capacity. The bigger the insert, the more likely to see fewer inserts in the cutter too.
