Drill bits are cutting tools used to make round holes. We have drill bits in many sizes and styles, most of which are made for cutting metal. The diameter of the drill bit refers to the edge that cuts the hole, the shank refers to the end of the drill bit that fits in the drill.
The shank is the end of a drill bit grasped by the chuck of a drill. The cutting edges of the drill bit contact the workpiece, and are connected via the shaft with the shank, which fits into the chuck.
