Morphology
The compound is transparently compositional: 'expansive' = capable of expanding and 'bit' = the cutting part of a drill, so a B1 learner who knows both words can infer it is a drill bit that expands or can be adjusted to different diameters. Although the term is technical, the literal meaning follows directly from the constituents and is predictable across languages.
Etymology
Expansive bit. The noun expansive bit comes from the tool's ability to open its cutting blade; the word expansive here means 'able to open wider' and bit is the cutting part. That's why it means 'a drill bit that can make holes of different sizes'.
