New screw for fixing tools, characterized in that, at the end that performs the pressure on the tool, has a hemispherical housing in which it is admitted (with some slack), and retained a steel ball provided with a flat face that falls to the outside and that is with which the contact with the repeated tool is achieved, although this does not present a regular seating plane, since said ball acts as a spherical ball.
