Metal-on-metal contact creates immense resistance, which increases the required force and can lead to work hardening of the surface. This lubrication reduces friction, allowing the cutting edges to slice through the material with less resistance and significantly less wear.
Mitigating Heat and Avoiding Steel Tempering During Metal Drilling
When a drill bit rotates and applies pressure, the kinetic energy is converted into thermal energy through friction. Best Practices for Application.
Drilling metal presents a unique set of challenges, primarily because the process generates significant heat and friction at the point of contact. Preventing Workpiece Adhesion A specific and damaging issue when drilling metal is the tendency for small particles of the workpiece to weld onto the cutting edge of the drill.
Avoiding Heat-Induced Work Hardening and Steel Tempering During Drilling
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. This reduction in friction directly translates to less energy consumption, smoother cutting action, and a dramatically extended tool life.
