Morphology
The meaning 'a drill bit with deep helical grooves' is directly and transparently derived from combining 'twist' (a winding/helical shape) with 'drill' (a tool for making holes). This is a compositional technical compound, so a B1 learner who knows both constituents can infer it denotes a drill characterized by a twisted shape.
Etymology
Twist drill gets its name from the tool's shape: the cutting part is a twisted spiral, so the twist in the name points to the spiral and the drill to making holes. That's why it means 'a drill bit with spiral grooves used to cut holes'.
