Abstract
An improved chuck, characterized in that the base work piece, acting as a support for the means for holding the tool, has a helical channel of semicircular section, with two entries or fillets, which serves as a guide to a ball that makes a function of nut, producing the lifting of the chuck and closing of the claws.
