I want to mill that shank down to 1/2" and use the tool. I tried using the 1/4" 4 flute and did a bit of a test and it was like grinding rocks
I've got a mini mill. Before I got lucky and bought a large batch of US end mills, I bought a couple of sets of cheap Chinese end mills, viz:

For the money they work very well. And if I screw something up I'm not going to cry over them at that price.
They have free shipping to the USA, don't know about Canada.
If it makes you feel any better about milling MS with a mini mill, I'd say I felt the same way at first but found out I was too worried for nothing, this is how I made it work for me:
I don't use any end mills bigger than 1/2", don't remove more than .020" in each pass(.010" is even better),always lock the axes not in use. use cutting oil liberally. find the right RPM/the sweet spot for the diameter of the end mill.
Another item you should think of buying is, a portable metal cutting bandsaw , it helps to remove most of the material before you even get to milling it, a roughing bit is also a must have, it removes mild steel almost as quickly as aluminum.
