Which of the following options is a function of the drill bit?

The function of a drill bit is to create a circular hole by removing material from a workpiece. As the drill bit rotates, its cutting edges grind and chip away at the material, allowing for precise and controlled hole diameter and depth. This is a fundamental aspect of machining processes, where a specific shape or dimension is required.

While other components in a drilling system may help with power distribution, cooling, or solidifying materials, the primary purpose of the drill bit itself focuses on the removal of material to produce holes, making the creation of a circular hole its essential function. This differentiates it from elements that support the drilling process but do not perform the cutting action.
