This softening process, known as thermal annealing, causes the edge to roll and deform rather than cut, resulting in oversized holes and a frustrating cycle of constant sharpening. If this heat is not dissipated, the metal at the cutting edge reaches a critical temperature where the steel loses its temper.
How Proper Cutting Oil Prevents Metal Welding During Drilling
Metal-on-metal contact creates immense resistance, which increases the required force and can lead to work hardening of the surface. Without proper intervention, this energy rapidly degrades the tool, leading to dull edges, poor hole quality, and premature failure.
High-performance formulations are specifically engineered to have a high thermal conductivity and a high boiling point. A well-lubricated cut results in a smoother finish, reducing the need for secondary finishing operations.
Prevent Metal Drilling Welding with Proper Cutting Oil Lubrication
This thermal stability ensures that the microstructure of the steel remains intact, preserving the sharpness and strength of the cutting edge throughout the operation. Choosing the right formulation ensures optimal performance and protects both the tool and the integrity of the workpiece.
