Can any of you imagine what a nightmare that would be to do on a mill? I thought milling lightening holes into our chassis pieces was nightmarish...

And this is why CNC was created
If I only have a manual mill I usually use a 3/4inch drill bit to do my lighting.

I used a 3/8 inch 2-flute end mill. I started our with a 4-flute and learned that 4-flutes and aluminum don't mix it melted my piece. And the absence of WD-40 caused the aluminum to stick inside of the bit .
Also, it was manual.
