Just realized running dry on aluminum is way faster than using coolant
Spent 2 years flooding the workpiece like the old guys taught me until a mentor at a shop in Detroit last month showed me a dry finish cut that dropped cycle time by 40% with no chatter, anyone else ditch the flood for certain jobs?

Well I'll be, you just described my exact experience. I tried dry finishing on some 4140 pre-hard last month and it cut my cycle time by a third with a better finish. Just make sure you've got good chip evacuation and keep an eye on your speeds, because heat buildup will get you if you push too hard.

Man, hell yeah. Dry finishing is the real deal for a lot of stuff. Flood coolant just makes a mess and hides what the tool is actually doing. I've been running dry on steel for the last year and my tool life actually went up. People get too stuck on what the old timers taught them.

Is it really that big of a deal though? Plenty of guys run coolant and get fine tool life without making a mess. Maybe the improvement is more about your specific setup than dry finishing being some secret weapon.
