Just compared a 2-flute and 4-flute endmill on some 6061 aluminum
I was running a job with deep pockets and the 2-flute was clearing chips way better, no heat buildup at all. The 4-flute kept clogging and left a worse finish on the walls. Is a 2-flute just the go-to for aluminum removal or are there times you'd still pick the 4-flute?

Depends on the finish pass for me.

Mine usually looks like a toddler did it.

See, a perfectly dialed in machine makes all the difference... that "toddler" look is just user error at that point.
