Morphology

spade + bit

The noun is compositionally built: a 'bit' (drill cutting part) that is shaped/used like a 'spade' (flat-bladed tool), so the form and function are directly inferable from the constituents. This follows a common English compound pattern and would be predictable to a B1 learner who knows both words.

Etymology

Spade bit comes from the tool's shape: spade is a flat shovel blade and bit means a small drill part, so the drill piece looks like a tiny spade and is used for 'making wide holes' in wood.
