the.com/drill bit
The pointy part doing all the work while the drill gets all the credit.
means The sharp, replaceable tip that actually cuts or bores the hole, mounted in a drill that just supplies the spin and the muscle.
from 'Drill' traces back to the Dutch 'drillen' (to bore, turn, or whirl), which arrived in English around the 1600s alongside the tool itself. 'Bit' comes from Old English 'bite' / the verb 'bītan' (to bite) — the same root that gives us the bit in a horse's bridle, a piece meant to be gripped and to gnaw or grip in turn. Put them together and you get a literal description: the biting part that does the boring.
