Abstract
A quick release drill chuck for surgical and dental instruments, particularly high speed drills powered by rotary air motors, is disclosed. The chuck engages the shafts of drills or burs and is actuated without the use of additional tools while providing a self-locking feature to insure against inadvertent loosening of the chuck.
