In regards to the performance of Unist MQL Systems, Both Armo and Abuma believe it is an excellent product and well worth the investment. Over the past few years we have implemented Unist systems on metal cutting saws, milling and drilling machines. We have seen considerable improvements in productivity, tool life and machine cleanliness. We have been able to eliminate coolant usage almost entirely. We employ skilled Machinists and Toolmakers that have 20 plus years of industry experience that prefer this product over traditional coolants. After the initial investment the cost to operate these systems is very small. The cutting fluid is applied in very precise volumes and location on the cutting tool. Very little fluid is consumed, 4 liters of Unist Coolube under most conditions last for months. One of the most obvious advantages of Unist MQL systems over coolant is machine cleanliness. Not only does the machine stay very clean, so does the entire work area and work pieces. The metal chips are very easily cleaned up as they are not covered in sticky residues. I recommend this product. It is definitely worth a trial.  

After changing from flood coolant to a Unist Coolubricator^® and Coolube^® 2210AL lubricant on our Brother TC-32A, we were able to increase our effective tap life from 450 pieces per tap to 1500 pieces per tap. The tap is an M4 x 0.7 bottoming cut tap in CF-8 stainless steel. We are happy with how clean the parts are as well but the increase in tap life is what pleased us the most.
