Using cutting oil during broken bolt removal serves various essential purposes, one of which is to prolong the life of the drill bit. When drilling through metal, the friction generated can cause significant heat, leading to wear and potential damage to the drill bit. Cutting oil serves as a lubricant, reducing this friction, which helps to dissipate heat more effectively and keeps the drill bit cooler during the operation. This lubrication not only extends the drill bit's lifespan but also maintains its sharpness and efficiency in the job at hand.

While other benefits of cutting oil may include facilitating quicker drilling and reducing friction, the primary aim in this scenario is to protect and extend the life of the tool being used. Additionally, while cutting oil can contribute to smoother surfaces, this is more of a secondary effect achieved during the drilling process rather than the primary purpose of its use in bolting operations.
