High-performance formulations are specifically engineered to have a high thermal conductivity and a high boiling point. Work hardening makes the material more difficult to cut, placing additional stress on the drill.
Mastering Heat Control with Cutting Oil in Metal Drilling
The Science Behind Heat Management Heat is the primary enemy of precision drilling, and its management dictates the success of the operation. This lubrication reduces friction, allowing the cutting edges to slice through the material with less resistance and significantly less wear.
How Cutting Oil Works as a Coolant Cutting oil functions as an effective coolant by absorbing the heat generated during the drilling process and transferring it away from the tool. For ferrous materials like steel and stainless steel, a heavy-duty oil with extreme pressure (EP) additives is necessary to handle the high stress.

When a drill bit rotates and applies pressure, the kinetic energy is converted into thermal energy through friction. These packed chips act as a grinding mechanism, scoring the sides of the hole and causing tool failure.
