Buy them by the numbers, DP, pressure angle and tooth range that they will produce, the tools in the picture are well marked (until used) , for instance the tool in the lower right corner is marked , 20 DP, 14 1/2 Deg. PA, 55-134. What could be simpler than that? Naming conventions are meaningless if there is no governing body to enforce them.
Problem was the one I brought was only sold as 20 DP, 14,5 PA, #5. Can't see a tooth count on the cutter from the picture provided but it does appear to have 'Detroit' written on it so I'm now expecting it to be 21 to 25 teeth - not actually what I wanted.
