<p>One example of an apparatus for gripping and rotating a tubular includes a mandrel having a longitudinal axis; a first slip disposed on the mandrel; and a second slip disposed on the mandrel axially spaced apart from the first slip, the first slip and second slip operationally connected to move in unison axially; wherein when the first slip and the second slip are moved axially from a first point toward a second point the first and second slips extend radially into gripping contact with the tubular and wherein rotation of the mandrel further urges the second slip radially away from the mandrel.</p>
