Abstract
Improvements in the construction of drill chucks, characterized in that the chuck is constituted by a body that is mounted on the machine tool and has the internal thread for a hollow screw, which receives the tool and carries longitudinal slots, which serve as guides to the grippers of said tool, whose claws are crossed by a spring that tends to join them.
