sweet spot


Dial in the "Sweet Spot"

With MQL, individual metal cutting applications each have their own "sweet spot" or precise amount of fluid necessary for optimum efficiency. Too little fluid, or too much fluid and tool life can suffer and fluid can be wasted. The Coolubricator™ gives you precise control over fluid output with separate fluid and air output adjustment. This means finding the sweet spot for your application is a breeze and once it's set, you can count on the Coolubricator™ to deliver the perfect amount of fluid again and again.

  • coaxial

  • Separate Air & Fluid

    is the key to delivering consistent atomization and fluid distribution over extended lengths of supply tubing. This is where the patented Unist Co-Axial Nozzle steps in. Fluid and air are kept separate until they are combined at the nozzle tip. This creates an evenly atomized spray and eliminates messy drips. Be sure to order your Coolubricator with Co-Axial hose and nozzle to maximize your lubricant delivery!
