Finally got my scrap rate on those tricky 6061-T6 parts down from 12% to under 2% after switching to a 3-flute carbide endmill and bumping the SFM to 850.
What's your go-to tool and speed for aluminum that just won't stop gumming up?

Honestly, I've had the opposite happen. Pushing SFM that high on 6061 just made things worse for me, melted chips everywhere. I stick with a sharp 2-flute HSS endmill around 500 SFM and flood coolant. The slower cut lets the chips actually break and clear.

Flood coolant's the real hero there.

Wish I had a magic answer, my go-to move is usually just yelling at the machine. Honestly, my garage floor is basically a museum of failed aluminum cuts, I've tried so many things. Lately I'm just running a cheap 3-flute with a ton of air blast and crossing my fingers, seems to work okay until it doesn't.
