Is it recommended to use drill lubricant before each hole when working with titanium?

Using drill lubricant before drilling holes in titanium is indeed recommended. Titanium has a high tensile strength and can work-harden quickly when subjected to cutting processes. This can lead to increased tool wear, poor surface finish, and potential drilling failures. The application of a drill lubricant helps in reducing friction, dissipating heat, and providing a smoother cutting operation.

Additionally, using lubricant reduces the risk of the drill bit seizing in the material, which can cause breakage or inaccurate hole placement. It helps prolong the life of the tool being used and improves the overall efficiency of the drilling operation. Given the properties of titanium, employing proper lubrication is essential for achieving the desired results when drilling, hence making this recommendation valid and important for anyone working with this material.
