Coolubricator: The perfect MQL metal cutting companion

With its precision positive displacement pump and individually adjustable air and fluid volumes, the Coolubricator™ is the perfect Minimum Quantity Lubrication solution for metal cutting.This patented device, which is ideal for dispensing tapping fluids, limits the amount of fluid used, reducing waste and mess in your workshop. The following benefits create a win-win-win result for you in terms of better tool performance; a non-toxic environmental impact; and ongoing money savings gained from proper tool care:

  • Reduces fluid usage
  • Promotes a clean and safe work environment
  • Prolongs tool life
  • Improves cut quality
  • For best results use Unist’s environmentally friendly Coolube®
  • Dry chips - higher recycling value

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.

coaxIllusSeparate 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 maximise your lubricant delivery!

The Coolubricator has a variety of applications. It can be used for metal sawing or drilling, as well as tapping and milling. It can also help with routing and turning and broaching metal for precision and efficiency. It is the ideal solution for use in machining and the manufacturing of metal components.
