You may lose the temper on the tool, causing it to wear out or even melt, and depending upon the material of the tool, it could even explode. As you can see, making sure that the tools and the part remain cool while the machining is happening is critical. Now, there are several factors to consider when selecting the coolant type. First, what are the materials that you're dealing with? There are various types of coolants specifically made for the different materials of your tools and workpiece.

There are natural and synthetics as well. Third, if you…
