Cutting fluid is a type of lubricant or coolant used in CNC machining. It helps regulate the temperature of the machine, prevents corrosion, minimizes wear and tear, and increases its lifespan.
Cutting fluids can be divided into three categories – water-miscible, neat oils and synthetics. Emulsions remain the most widely used today.
What is Cutting Fluid?
Cutting fluid is a liquid used in precision milling, drilling and turning operations. It reduces friction while increasing tool life while protecting both machine and work piece from rust and corrosion.
During machining, the cutting tool expends almost all its energy as heat. Coolant is then applied to both tool and workpiece in order to dissipate this heat.
Coolant can also help to lubricate the interface between a tool and its chip, decreasing friction and heat generation to extend tool life and optimize surface finish.
What is Motor Oil?
Motor oil is an essential fluid that keeps your engine running efficiently by lubricating moving parts. By using motor oil regularly, you can extend the life of your vehicle and save yourself costly repairs.
Motor oil’s primary purpose is to lubricate the engine by decreasing friction between components such as pistons, valves and camshaft. It also assists in running the engine more efficiently by decreasing heat generation.
Motor oil comes in various varieties, such as conventional, synthetic and Semi-synthetic. Which type you use depends on the age of your vehicle and local climate conditions.

Cutting Fluid vs Motor Oil
Cutting fluid is a lubricant that transfers heat away from cutting tools to protect them from overheating. Additionally, it reduces friction and wear on tools, extending their usefulness.
Cutting fluids come in a range of varieties, such as water-dilutable coolants, neat-based lubricants and synthetic lubricants. The type of cutting fluid chosen depends on the task at hand and material to be cut.
While motor oil on the other hand is used to lubricate engine parts, reduce friction, clean, cool and help to protect the engine. However, synthetic motor oil does a lot more than just lubricate. It does a superb job at providing engine wear protection, and engine performance enhancement as well as complete protection of all moving parts.
As you can see, cutting fluid has the ability to act as both coolants and lubricants. The the main difference between the two is that cutting fluid is capable of lubricating the interface between the cutting tool’s cutting edge and chip whereas motor oil has the potential to lubricate and reduce the friction between moving parts.
