1. A casing manipulation assembly for manipulation of a casing member and comprising:
a central mandrel; a housing circumferentially surrounding the mandrel and being axially moveable with respect to the mandrel as the mandrel is rotated; a slip assembly having a slip member that is set within the casing member by axial movement of the mandrel with respect to the housing; and a torque locking mechanism to selectively prevent rotation of the mandrel with respect to the housing.
