aRM,
I'm always willing to help. With you being in South Africa I know it's harder to get specific tooling. Chances are that you'd find a Walter cutter there or nearby that is a metric size, so those will also have a metric bore. Something in the 50mm size would have a 22mm bore, so you would look for an R8 to 22mm pilot diameter shell mill arbor.
For your application you might prefer a 45º lead angle face mill, such as the F4080 or F4033 like I have. Those both also have 8 edges, and the WKP25S grade is available for the D2 tool steel you are milling. Your limiting factor would be how much power (Kw, HP, Nm-m) does your spindle put out. There will be many options on them for insert size, tolerance and chipbreakers, number of inserts for a given size, depth of cut maximum, and grades.
Do you need a square shoulder cutter, or can you use a true face mill? How much power does your machine have? What is your typical depth of cut, what is the maximum that you'd want?
