Kool Mist 560-77#60M PORTaMIST Unit w/1 Gal #77 & 4 OZ #78 Coolant

The mist system performed ok. The negatives are that the misting is highly dependent on the pressure of the compressed air line. Typical compressor units operate between 90psi and 120psi. When the mist system is set to spray uniformly at 120psi, the spray changes appreciably as the pressure drops to 90psi. If set for 90psi, the spray is much too strong at 120psi. and, an intermediate setting does not perform well at either the low or high pressure. the system only performs well at the specific pressure set during adjustment.I also purchased the misting fluid as a package with the misting system. I found that this fluid, being water based, caused appreciable rusting on steel surfaces, whether the machine or the machined part. Unless I immediately cleaned the machine and the part at the completion of my work, I found rust starting the very next day. I prefer oil based cooling systems much better since most of my work is steel based. With non-ferrous metals this cooling fluid would perform satisfactorily but it would still greatly effect the ferrous surfaces of any machine.I much prefer systems that deliver the coolant in a steady stream or as a bath, the misting is just too difficult to contain within the small work environment of a lathe or mill tool.The pluses are that the vendor shipped quickly and that the components of the system are well made.I would not recommend this system for single machines such as 10x42 inch lathes or similar milling machines.

Great product. The cooling action is fantastic - I punched a 9/16" drill bit 2 inches into a piece of stainless bar stock just as fast as I could turn the crank on my tailstock, and when I pulled it back out afterwards the bit was still cold to the touch. I might wind up buying more of these for the rest of my machines!

I have bought four of these kits now. We put one on a CNC router table to cool the bit when routing aluminum. Worked great, was easy to set up. Ditto for the second one we installed on a circular saw for use in cutting aluminum tubing. Two more went on saws. Guess the best endorsement of a product is when the customer keeps buying them.

The seat for the small needle valve or the valve proper is miss-manufactured and the air will not shut off. The instruction sheet shows typical air regulator settings for the various units but those part numbers don't equate to the kool mist units. Simple stuff that shouldn't happen if the manufacturer took things seriously.

great product

Perfect for us.
