Kool Mist vs straight water?

[Suzuki4evr]

Syntol SB to be precise, but you get a lot of different products. I went through a process of elimination and I am happiest with this one.

I like Kool Mist 77 with an inexpensive, $12 direct from China mister unit. It lubes, prevents rust, and is totally non toxic. I mix it 32:1 (water to coolant) Two liters of mix (containing about 2 ounces of K-M 77) lasts me for about 12 hours of use. It works great. My lathe has factory flood coolant installed on it, but the only thing that has ever been in the tank is a little dust. Way too much mess for a home shop, in my opinion.

Before going to a spray mist setup, I used to use WD40 as a flood coolant. But, then when I started running higher feed rates, the WD40 would smoke profusely. One time this dude came into the shop because he thought something had caught on fire.

That smoke comment randomly reminded of Cheech and Chong
"Man, am I driving ok?"
"I think we're parked man"

I usually run the mister with air only (seems less messy) and spritz WD40 as needed. If it's a long running job then I let the mister pull the WD40 as droplets (not mist). You're right though, deep and heavy cuts makes WD40 a smoke bomb but so far it hasn't been an issue.

Sounds cheaper than WD40 but since I'm near the ocean I'm always a bit apprehensive about water/humidity and metal. Do you mix it with regular tap water or distilled water?

And because of rust issues, I always spray my mill table down with WD40 after I have finished my work for the evening. Not a huge deal, but necessary. I have also started to run a shop fan on low in a continuous state to keep air circulation going which helps a lot.

Spraying WD40 to prevent rust is not very effective. Its a lubricant not a rust preventative. Air circulation works better at rust prevention than WD40 does in my experience. Starrett M1, or similar spray is much more effective for preventing rust on a mill table or tooling. Kool Mist 77 works fine, I like Rustlick better but they both work, for me Rustlick is less of a irritant.

I’ve used nothing but air for years, just enough air flow to blow the chips into a crude cardboard chute, leading to the to the trash can. When doing steel I use a magnetic screen, to catch the majority of the chips.

I use tap water. I agree with Doubleeboy that using WD-40 as a rust preventative is not the best choice. It is nearly all kerosene or similar. Way oil is much better as a rust preventative.

I use koolmist77 and have no rust issues. 1gal of concentrate makes 33 gal of coolant and Amazon will deliver it right to your doorstep.

Also a Koolmist 77 user. very happy, no rust and inexpensive.

I use KoolMist on my mill and lathes. Never had any problems with rust. On some applications, I cut the coolant flow down so that I'm using practically air-only. It's a great product.
