Tool for obtaining spherical concavities, characterized in that the tool itself emerges to the outside by an axial groove made in a block that acts as a support, having that possibility of longitudinal displacement in relation to the cavity to be practiced and with angular displacement in a plane horizontal in an amplitude greater than 180º and fixed to an axis by conventional means and with possibilities of rotation, by virtue of a set of conical pinions that transmit their movement by a shaft and drive wheel with or without a gear reducer group.
