By drawing heat away from the cutting edge, the oil keeps the metal within its optimal working temperature range. Reducing Friction and Extending Tool Life Beyond temperature control, the role of cutting oil in reducing friction cannot be overstated.
How Cutting Oil Thermal Stability Prevents Steel Tempering Issues
This reduction in friction directly translates to less energy consumption, smoother cutting action, and a dramatically extended tool life. The oil creates a thin film that lubricates the interface, minimizing the direct contact between the flutes and the hole wall.
Metal-on-metal contact creates immense resistance, which increases the required force and can lead to work hardening of the surface. Selecting the Right Formulation Not all cutting oils are created equal, and selecting the correct one depends on the base metal being drilled.
How Cutting Oil Thermal Stability Prevents Steel Tempering During Drilling
A well-lubricated cut results in a smoother finish, reducing the need for secondary finishing operations. High-performance formulations are specifically engineered to have a high thermal conductivity and a high boiling point.
