What can happen if a drill bit is not lubricated while drilling titanium?

When drilling titanium, lubrication plays a crucial role due to the material's unique properties. Titanium has a high tensile strength and is prone to work hardening, which means it becomes harder as it is deformed. If a drill bit is not lubricated while drilling titanium, it can lead to significant wear of the drill bit.

This wear occurs because the friction generated between the drill bit and the titanium heats up the tool to a point where it can dull quickly, leading to a reduction in cutting efficiency and the potential for tool failure. The absence of lubrication can also cause the drill bit to bind or seize in the hole, which can further increase wear and damage, not just to the bit itself but also potentially to the workpiece. Proper lubrication, therefore, is essential to minimize wear, extend tool life, and ensure effective machining of titanium components.
