You may be best served by buying a 10 pack of 2 flute ball end and 2 flute strait cutters. Work out your feeds and speeds and the rest from there. I just cut out a mini table saw in aluminum on a old ox router with these https://www.amazon.com/HQMaster-Carbide-Router-Acrylic-Hardwood/dp/B010NI39WO/ref=sr_1_9?crid=1BLCW7JK9CZKS&keywords=2+flute+carbide+end+mill&qid=1664866092&qu=eyJxc2MiOiIzLjk0IiwicXNhIjoiMi43NSIsInFzcCI6IjIuMTMifQ%3D%3D&sprefix=2+...
Step 1. Download MillrightCNC app on your phone / tablet
Step 2. Purchase these bits on Amazon for dirt cheap : https://www.amazon.com/gp/product/B010NI39WO/ref=oh_aui_search_asin_title?ie=UTF8&psc=1
Make sure you purchase T6061 aluminum (it is easier to cut)
Here are the settings I used in the vid:
Feedrate: 770mm/min
Depth of Cut: .6mm
Spindle RPM: 17k

Here is a pic of the final result of what I was cutting:
