Coolant debate for aluminum cuts has me rethinking my process.

Some say coolant is key for tool life and finish, but others push dry for less mess and faster cleanup, what's your take?

This coolant debate? Isn't it overblown?

My last dry cut on some 6061 looked like I was trying to start a campfire. Switched to a good flood coolant setup and my inserts last three times longer now. The mess is real, but so is not buying tools every other week.
