What is a keyless drill chuck?

Keyless drill chucks are used for rigid clamping of drill bits between their self-centring jaws. One major advantage of these chucks over their traditional counterparts is that they do not require a key for operating the jaws. The jaws can be hand tightened or loosened easily. This further eliminates the issue of broken gear teeth that a keyed chuck may face over time and usage. 

The chuck is provided with a precision ground female Jacob taper that sits on a matching tapered arbor or spindle. Keyless drill chucks are manufactured for right-handed operations only. During the operation, the rotating drill bit tends to push the chuck upwards into the spindle thus producing a firm binding action between the two parts.
