Drill Bit Shank
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. In many cases a general-purpose arrangement is used, such as a bit with cylindrical shaft and shank in a three-jaw chuck which grips a cylindrical shank tightly. Different shank and chuck combination can deliver improved performance, such as allowing higher torque, greater centering accuracy, or moving the bit, but not the chuck, with a hammer action.

Famous quotes containing the words drill and/or bit:
“Swift blazing flag of the regiment,
Eagle with crest of red and gold,
These men were born to drill and die.
Point for them the virtue of slaughter,
Make plain to them the excellence of killing
And a field where a thousand corpses lie.”
—Stephen Crane (1871–1900)
“One certainly has a soul; but how it came to allow itself to be enclosed in a body is more than I can imagine. I only know if once mine gets out, I’ll have a bit of a tussle before I let it get in again to that of any other.”
—George Gordon Noel Byron (1788–1824)
