I have (had) a Kool Mist. Hated the adjustments. Seemed like I was always tweaking it. It never started with the same flows. I got one of the cheap, "two-valves on the body" ones on eBay. Absolutely love it. Bob is right, you want small beads of coolant, not a fine mist. There a lot of these out there. This is the one I got:

That is the same type I use. It works great, no issues. I bought mine from Aliexpress for under $15, free shipping, takes weeks to arrive. Many vendors sell the same product, just look at the prices, the fine print, and the vendor reviews.

I will probably buy two more sets at that price, one for the lathe, and one for the mill. I have factory flood coolant on my lathe, but the only thing that has ever been in the reservoir tank is dust. Flood coolant is too messy and eventually stinky in a home shop, IMO. Mist coolant, no problems, works just fine.

Thanks for the reply’s guys looks like ima order some koolmist 77 tonight

I have the regulator set at 20psi. Then open the air valve enough for chip removal then open the coolant valve just till the temp drops in the air flow. 20 min. on the mill today I used less than 1/2 teaspoon coolant.
I’m going to have to make some adjustments I’m guessing Id be at 1/4 cup in that same 20 minute time frame
 
On my surface grinder, I use a bit less than 1 liter(quart) of Kool-Mist 77 32:1 mix in 4 hours, with it running nearly full time. That is because keeping the heat down with wet coolant is how flat surfaces are made flat, and coolant wet on the part also improves the surface finish. On a lathe I would likely use much less, on a mill, less yet,

Hey bob how did you mount yours to your mill? Seems like I remember seeing a build thread you did but I can’t seem to find it.

I currently only have mist coolant mounted on my surface grinder, and use cutting oil and Anchor Lube on my lathe and mill. It is not worth moving the mister from one machine to another for a cost of $15 each for the complete setup. As I posted above, I will likely purchase two more of the one I already have, they work well. I personally would not buy any of the other styles of mister units from China, the one I got has the separate valves for liquid and air, and I know it works well in all respects. Even the Locline copy tubing works fine, which it doesn't with many of the Chinese versions.
 
killswitch,

This is how I mounted my import mister on my mill. I took advantage of a rod mount on the head. I have two lengths of rod to accommodate different tool/holder/quill distances. I'm trying to think of a new rod configuration to move the mister body out further, and allow more rotational positioning. Otherwise it works great. I also have a 2-1/2" Loc-Line (orange nozzle) from a shop vac to pick up swarf and overspray. I'm running at about 40 PSI. That gives me a wide range of air jet with the needle valve when I'm not using coolant. (The tennis ball is to protect my head from the the corner of the quill encoder guard.)

Ken?, thank you for the picture!!!! I was going to over kill the bracket I’m definitely just gonna copy yours. I’m going to play with it a when I get the rest of the parts Wednesday. How much coolant do you think your running per hour on average?

Bob, I ordered a couple a year or so back when that post with the eBay link was going around. I think I’ve about 50-60 bucks in this set up I’m plan on making one for the lathe here soon. I gave a flood system on it now and it’s just a big ol mess.

Thanks again for the comments
