carbide insert lingo

[Dancy]

I have an Interstate shell mill.
RFA-500-RD12-150
a quick internet search finds this
Dorian Shell mills
and more digging, this
Dorian-inserts

My question is, what do the letter designations mean? RDHW, RDEX or SEKN?
something to do with geometry I am guessing. The inserts I need are:
diameter: .472 (12 mm)
thickness: .1875
hole dia: .220
rake angle: +15'

Is Dorian my only source for inserts?

This should help: Insert Designation Chart - provides ANSI and ISO designation code definitions for carbide insert shapes, relief angles, tolerances, chipbreaker codes, hole types, size values, thickness values, radius values, wiper lead angle, wiper clearance angle,
