Mist Coolant Lubrication Spray System for Milling Machine, CNC Lubrication Spray Pump Mini Mill for Metal Nozzle Lathe Hose Keep Cutting Tools Cool

Works great and a fraction of the price as the original.

Seriously this is the best mister I have used. The venturi effect is so effective that barely any airflow draws up coolant and the compressor doesn't come on every 5 minutes like my old one. The coolant and air volumes can be adjusted independently to get the right mix. It is well built, the nozzle stays where you point it, and works far beyond expectations.

It works very good to fine tune air pressure and mist oil separately. I have it setup on my 3018 cnc mill which doesn't need a ton of air or oil mist. It is 3 links too long for my setup so iI have to have a bigger arch and a little zigzag to be exactly where I need it. I popped it apart to see if I could remove a few links but there isa sleeved tube running down the middle , attached to the nozzle. I snapped it back together and decided to have the longer run which is better than air or oil leaks. I really like the performance and rigidity of this just wish it was a bit shorter. It does stay exactly in place though.

I am so extremely glad that I did not get a lesser quality one, I absolutely love it!! And here's a wonderful tip: I took painters tape and taped the side that I wanted mounted, and tapped the surface that I wanted it to be mounted to, and I covered both the surface of the back of the tape on both the unit and the mounting surface with some dollartree supper glue and stuck the tape together to eachother. Don't kid yourself thinking this isn't the greatest idea because I do this on cnc machine to mount a piece of aluminum stock to the work table and machine parts and they hold really tight and when im done; I just pry up one corner of the finished part and peel the tape off and all surfaces are protected check it out on YouTube and look up cnc painters tape fixturing with supper glue its really a great idea. Also; I only had the 6mm blue plastic tube and the connector called for 8mm so I heater the tube and stretched it until about 1 inch of the tube was large enough to fit over a pencil and it worked beautifully. And holds 120 lbs with no issues. Also the duel adjusters is so versatile that you can make it do anything you like, low air low mist, medium air less mist for less ventri liquid draw, massive air with infinitely ultra-light ventri liquid draw, im telling you; that you have ultimate control over every variation possible with this unit. What I plan to do first is test the lightest liquid delivery with the finest mist and explore how to make the liquid evaporate as soon as it lands on the hot cutter bit so that the evaporation will introduce a refrigeration effect by releasing coldness from turning liquid into vapor and have no liquid mess to clean up, and no coolant waste and good chip clearing and effectively deposit oil on the tool at just the right degree. If I really like something then I enjoy a nice fun show and tell to all my fellow tinkerers. Hey this ones going right in my toy box boys and girls. Lol

This device lets me grind hardened steel knives on my grinder without worrying about ruining the temper. Increases my efficiency and I do not have to constantly dip the blade to keep it cool. I can keep the blade against the platen and grind away.

Works great! I use it on my 2x72 belt grinder and it works very well. Very good value.

Not a huge amount to write about this piece, because I want to get back to the shop to use it. When you're machining certain metals, a mist of fluid is quite useful. You can have a friend stand there with a spray bottle, squeezing at intervals, or you can get a fun toy like this. The fun toy won, obviously. It works exactly as expected, and I don't need to rope a friend into being Squeeze Bottle Dude for the day.

I purchased this to use with a grinder to keep steel cool while grinding. When I received the item I noticed there were no instructions. I rarely read instructions, but in this instance I needed to know the operating pressure for the air hose attached to the sprayer, as well as the size of tubing I needed. I ended up buying the wrong size tubing before I learned by reading reviews that 10mm tubing was needed to work with the supplied coupler. I also found the working pressures in the original listing and was able to convert them to PSI for my use. Overall a decent item, but it's missing several parts you will need to actually make it work such as supply lines and couplers, and a method to attach the sprayer to thing (I found magnets that worked well).
