Terms of the Trade: What Is a Shank?

The shank of a drill bit is the end of the bit grasped by the chuck, or clamp, of the drill. There are many different kinds of shanks, including the brace shank, straight shank, hex shank, square shank, sds shank, triangle shank, threaded shank, and morse taper shank. When combined with different chucks, shanks can produce different effects such as higher torque or greater accuracy.
