For metalworking processes such as machining, drilling, and milling we have come up with specialized oil known as cutting oil. These oils serve multiple purposes during metal-cutting operations. Firstly, they act as lubricants, reducing friction between the cutting tool and the workpiece, thereby minimizing heat generation and extending tool life. Secondly, these oils help to cool the cutting zone, preventing the workpiece from overheating as well as maintaining dimensional accuracy. Additionally, cutting oils aid in chip evacuation, improving the efficiency of the cutting process while also providing corrosion protection to the workpiece and the cutting tool.
