Morphology

center + bit

The meaning is directly built from 'center' (middle point) + 'bit' (the cutting part of a drill): a drill bit with a central point for guidance follows straightforward noun-noun compounding. Although somewhat technical, the sense is compositional and a B1 learner who knows both words can reasonably infer this function.

Etymology

Center bit comes from its shape: a small sharp center point that finds the right spot and a cutting bit that makes the hole. That pointed center keeps the drill steady, so the tool is used to 'guide' the drill and make straight, accurate holes.
