1. A vibrating tool comprising
a power section comprising a rotor and a stator, the rotor comprising a plurality of lobes and the stator comprising a second plurality of recesses adapted to receive the plurality of lobes, the number of recesses greater than the number of lobes;
an axial shock assembly comprising a valve assembly comprising a rotating valve that is driven to rotate by the power section, the axial shock assembly adapted to vary fluid flow therethrough, wherein the rotating valve comprises a rotating disk having at least one port therein and a stationary disk having at least one port therein, such that the axial shock assembly is adapted to vary fluid flow therethrough by aligning and misaligning the at least one port of the rotating disk and the at least one port of the stationary disk; and
a lateral vibration assembly comprising an eccentric mass that is driven to rotate by the power section along with the rotating valve, wherein the eccentric mass is positioned with respect to the at least one port of the rotating disk so as to tune the vibrating tool based on a relative positioning of the at least one port of the rotating disk and the eccentric mass.
