Why is oil or grease applied to tools?

Tools are designed to ease the performance of various tasks, be it for construction, maintenance, manufacturing or any other application. They are mainly composed of metal or other sturdy materials and function through the interaction of various mechanical parts and surfaces.

Friction is the force that resists the relative motion between two surfaces in contact. When tools are operated, their parts and surfaces rub against each other, generating friction. Friction can cause increased wear and tear, energy loss, reduced efficiency and generate heat.

Oil and grease are lubricants that possess properties such as viscosity, thermal stability, and resistance to oxidation. They are designed to reduce friction, heat generation, and wear between moving parts or surfaces in contact. Lubricants also possess anti-corrosion properties, protecting tools from rust and corrosion.

Applying oil or grease to tools serves multiple purposes: 1. Reduces friction and wear: Lubricants form a thin film between the interacting surfaces, minimizing metal-to-metal contact and thus reducing friction and wear, prolonging the tool's lifespan. 2. Heat dissipation: The lubricants help to dissipate heat generated during operation, preventing overheating and potential damage. 3. Protection from rust and corrosion: Lubricants provide a protective layer that shields the metal surfaces from moisture and contaminants, preventing rust and corrosion. 4. Smooth operation: The reduction in friction helps tools to operate more smoothly and efficiently, improving performance and prolonging the tools' life. In conclusion, oil or grease is applied to tools to reduce friction and wear, dissipate heat, protect from rust and corrosion, and ensure smooth operation of the tools. Regular application of lubricants is crucial for maintaining and extending the life of your tools.
