If the drill bit is worn or damaged, what should you do?

When a drill bit is worn or damaged, replacing it is the most appropriate course of action. A worn or damaged drill bit can result in poor performance, including difficulties in drilling accuracy, increased friction, and the potential for further damage to the workpiece or the tool itself. Continually using a compromised drill bit can lead to more serious problems, including the risk of tool failure, which can endanger both the operator and the integrity of the assembly being worked on.

Furthermore, while sharpening a drill bit might seem like a feasible option, it may not restore its effectiveness if it is worn beyond a usable condition. Checking it with a gauge is helpful, but it does not address the root issue of a worn or damaged bit. In any professional setting, ensuring that tools are in optimal condition is crucial for safety and efficiency, which underscores why replacing the bit is the most responsible action.
