Drill bit
cutting tools used to create cylindrical holes
Drill bits are the working end of drill tools. Bits are interchangeable, meaning that they can be removed from the end of the drill, either to replace a worn part or to change the size of the part.
See drill bits (wells) for the large ones used for drilling wells in the ground.
