Morphology

counter-drill = drill (transparent) = counter + drill

The productive prefix 'counter-' meaning 'against' or 'opposite' combines directly with the verb 'drill' to yield the stated opposite-direction drilling meaning.

Etymology

Counter-drill combines counter- meaning 'against' or 'opposite', as in counterclockwise, and drill meaning 'to make a hole' or 'use a drill'. So, to counter-drill is to drill in the opposite direction to fix or undo a previous drilling action.
