Morphology

drill + bit

The compound is fully compositional: 'drill' (a tool for making holes) combined with 'bit' (a small cutting or replaceable part) yields the cutting piece attached to a drill. This follows a regular noun+noun compounding pattern common across languages, so a B1 learner who knows both constituents can readily infer the meaning.

Etymology

Drill bit comes from two simple words: a drill is the machine and a bit is a small piece that does the cutting. Imagine the little metal piece 'biting' into wood or rock, and that's why the phrase means the small tool part used to make holes.
