Morphology
The meaning 'a bit used for drilling' is directly and compositionally derived from 'drilling' (the process of making holes) + 'bit' (the replaceable cutting part of a drill). This noun–noun compound follows a transparent instrument+action pattern common across languages and standard English, so a B1 learner who knows the constituents would readily infer the meaning.
Etymology
Drilling bit is the small, hard part at the end of a drill. The words drilling and bit give a clear picture: the tip 'bites' into rock or earth to cut and make a hole, so the name reminds you it is the tool that does the cutting.
