ABSTRACT OF THE DISCLOSURE A hydraulically set anchor for setting well tools within a well for further production operations. The anchor may be connected to the lower end of the well tool or a running string for setting within a cased well bore. The anchor tool includes a mandrel with a fluid passageway to supply hydraulic fluid to a piston assembly. The piston assembly engages the slip assembly of the anchor used to set the tool. The slip assembly includes a movable upper slip cone which cooperates with slip elements to set the elements- into the casing. An interlock assembly associated with the upper cone and the mandrel prevents release of the slip assembly. The shallow angle of the slip cones in relation to the slip elements facilitates secure setting under minimum hydraulic pressure.
