Morphology
The noun-noun compound 'expansion bit' directly combines 'expansion' (growing in size) with 'bit' (the replaceable cutting part of a drill), so a learner can infer it is a drill bit that expands or allows making larger/variable holes. This follows a regular English compounding pattern and is cross-linguistically transparent, so a B1 learner who knows both words should be able to derive the meaning.
Etymology
The noun expansion bit comes from old drill parts that could push their cutting blades outward as they turned. The word bit is the small cutting part and expansion shows it can 'expand' or 'change size', so the name means 'a drill bit that can make holes of different sizes'.
