  Drill bit shank - Wikipedia, the free encyclopedia
The shank is the part of a drill bit grasped by the chuck of a drill.
The morse taper allows the bit to be mounted directly into the spindle of a drill, lathe tailstock or (with the use of adapters) into the spindle of milling machines.
The arbor of a drill chuck is often a morse taper and this allows the chuck assembly to be removed and directly replaced with the shank of a morse taper drill bit.

 Drill bit - Wikipedia, the free encyclopedia
The twist drill bit was invented by Steven A. Morse[1] of East Bridgewater, Massachusetts in 1861.
The centre of the drill bit is given not the straight chisel of the twist drill, but a spur with a sharp point and four sharp corners to cut the wood.
Center drill bits are used in metalworking to provide a starting hole for a larger sized drill bit, or a conical indentation in the end of a workpiece to mount a lathe center.

In conventional drilling equipment, the drilling bit has a splined shank which is received in the correspondingly splined end of an endmost tubular element (or chuck) of the drilling string, the cooperating splines preventing relative rotation between the drill bit and the chuck.
The bearing portions 37 and 38 of the drill shank are spaced apart significantly in the axial direction to resist as effectively as possible lateral tilting movement of the drill bit in the chuck.
Drilling apparatus according to claim 4 wherein the sonde is mounted in the drill string lia a resilient suspension arrangement to isolate the sonde from mechanical shocks.

 Automated drill bit recognition system - Patent 5160978
The drill bit feed track also has a drill stroker portion that sequentially receives each bit, and moves it through the second scanner at a certain uniform velocity, to ensure that the distance between each scan of the second scanner is uniformly spaced.
When the drill bit 14 arrives at the shuttle gate (the second gate) 30, then the first gate 20 is closed, and the data acquisition computer 102 is notified that drill data transmission from the first laser scanner 22 is complete.
Once one of these four routines identifies a given shank, the diameters beyond the shank, or in the case of a straight shank, the shank diameters themselves, are examined to establish a starting value for the maximum diameter of the drill.
