Honestly, I keep seeing people run their coolant way too thin and it's wrecking tools

Wait, how thin are we talking here? That's a great way to burn up a machine.

Has anyone else here actually measured the concentration with a refractometer instead of just eyeballing it? @caseys30 I get your point but most shops I've seen running thin are just guessing and end up with way below 5 percent which kills lubrication. A solid 7-8 percent mix might cost a little more upfront but it keeps the heat down without clogging anything if you maintain your system right.

And I gotta say I see it the other way honestly. Running coolant too thick is just as bad if not worse in my experience. It doesn't carry heat away fast enough and you end up with that gummy residue that sticks to everything. I've had guys on my crew try to save money by mixing it heavy and it just clogs up the lines and burns through inserts faster than if they'd run it a little thinner. A thin mix with good flow rate and pressure keeps things clean and cutting cool, at least from what I've seen. To each their own but I'd take a thin high flow setup over a thick low flow one any day.

Seen that ruin a brand new end mill.
