The liberal application of cutting fluid can improve these cutting conditions; however, the correct selection of speeds is the critical factor.

Cutting fluid is a coolant that also serves as a lubricant for metal-shaping machine tools.

Cutting fluid is a type of coolant and lubricant designed specifically for metalworking and machining processes.

Most metalworking and machining processes can benefit from the use of cutting fluid, depending on workpiece material.

Cutting fluid may also take the form of a paste or gel when used for some applications, in particular hand operations such as drilling and tapping.

It can also be called machining oil, tool oil, cutting fluid, and cutting oil.

Cutting fluid may also be pumped to the cutting site to provide cooling, lubrication and clearing of swarf from the workpiece.

This thin copper coating is more resistant to rough handling and the action of cutting fluid.

They also usually involve delivery of cutting fluid pumped under pressure through the tool to orifices near the cutting edges.

This is because of the lack of slurry, or cutting fluid, to reach the drill bit in order to keep it clean and effective.
