Do it yourself Mist Coolant?

Anybody got a good formula or trick for do it your self coolant to be used in mister, for steel machining?

I use "cool mist" brand coolant mixed with water and put in a plant sprayer plastic bottle. The nozzle is adjustable from mist to squirt gun and in between.
I use it when cutting steel with non carbide bits on the mill, lathe, and drill press.
With carbide cutters I let things get hot, and with cutting Aluminum things don't get hot even running fast.
I have tried another brand, "trim sol", but I don't like the smell and it stings my hands.

I can't understand what you want? A coolant recipe? The stuff is too cheap!

Its also unavailable in a sleepy little oilfield town on a Sunday, least of all one just prior to a national holiday.
I discovered my Cool Mist container was empty. Dry. Not there. Dust in the bottle.
I have at least 4 misters, from simple little magnetic based thingies to full blow solenoid operated tanks with multiple nozzles. But no coolant.
I need to mill a rifle scope base, out of steel. I dont like slathering oil with an acid brush.
So I simply asked if anyone had a "formula or trick for do it yourself coolant, to be used in a mister"
Shrug. Sorry for not being more clear.
I filled the mister with water and a dollop of DAWN dishsoap. Worked well enough. Kept the endmill cool, the soap added a little lubricity and kept my hands silky smooth <G>, and actually cleaned the top of my mill pretty well.
Anyone have a better alternative misting fluid BESIDES STORE BOUGHT which is of course..unavailable at this time?

Gunner, I think you are close to solving the problem. Since you are using soap and water maybe some oil mixed in would work. How about your cutting oil, soap, and water? I don't know how much dawn it takes to emulsify oil percentage wise but it should be easy enough to find out. Do you have any lard oil? Lard oil, soap, and water cooked on the stove to help it mix wouldn't stink too much. Try 1 cup oil, 2 tbs Dawn, and 2 cups water. When the oil is completely emulsified pour the mixture into a gallon of water. ERS

Yup, that would be the trick. Dawn and cooking oil. Some commercial coolant contains vegetable oil. The idea is to get some oil in it to provide rust resistance.
Sorry Gunner, but it sounded like you were going to try to make coolant, and I just couldn't begin to understand why. Ran out. Sunday. Makes sense now. Yeah, what Eric said.

SWAG - Find the MSDS for the stuff, and see what it's made from?
The base ingredients have to be something generic and spelled out as chemicals, even if they hide the corrosion inhibitors and a few special ingredients under a "trade secret ingredient number" dodge.

My step father makes his own cutting fluid for his mill, lathe and band saw. Beef tallow works into it some how.
I'm with Tom. Water soluble coolant is cheap and works well. I use one of the Valcool for everything but tapping. I have some in a mill I seldom use, and it can go years between replacements (topping it off in the mean time with water to replace that lost by evaporation)
There use to be recipes in the machinery's hand book. If memory serves me, I believe there once were some with whale oil and lead. Probably don't see that much today. Or porpoise jaw bone oil, what's up with that?

But given that Cool Mist evaporates to a lot of crystalline residue, who knows. Their MSDSs are not explicit as to ingredients.

And I'm sorry I'm not psychic...too bad, I had your answer...MILK! Just make sure you clean up good, milk sours and stinks.

    15th edition has quite a few formulas -- but not for a mister as far as I can tell -- more for flood coolant purposes.
    Good Luck,         DoN.

Try mountain dew and cigarette lung sputum. Top it off with some cat urine and windex just to add some sparkle to it

Gunner, I mill 62 rockwell high speed steel with Carbide end mills and use compressed air to cool the cutter and at the same time clear the chips. It works wel for me and there's no mess to clean up except the chips. Good luck .... Al Basham

If you make a venturi - it will cool as well (on the expanding end) A company sells those and they are well done.
