Morphology

rock + bit

The meaning 'a drill bit designed for drilling through rock' is directly and compositionally derived from combining 'rock' (the material) with 'bit' (the replaceable cutting part of a drill). This simple noun–noun compounding follows common morphological patterns and is cross-linguistically transparent, so a B1 learner who knows both constituents can infer the meaning.

Etymology

Rock bit comes from the simple image of a drill bit that 'bites' into rock. Picture a hard metal tip chewing the stone as it turns, and that's why the name now means a special drill part used to cut through rock.
