Morphology

core + drill

The meaning is directly and compositionally derived from 'core' (a cylindrical sample) + 'drill' (a tool), so a B1 learner who knows both words can infer it is a drill used to remove cores. This noun–noun compounding expresses a straightforward purpose/use and is a common, cross-linguistically transparent pattern.

Etymology

Core drill comes from what the tool does: it drills out a round core, a central plug of rock or concrete. So, a core drill is a drill made to cut out that cylinder for tests or to make exact holes.
