<p>An improved jaw (10) for a rod gripping device (69) is provided including a front, rod engaging face (14) with a plurality of teeth or studs (16) made of a material harder than the jaw body (20), such as tungsten carbide, with the studs (16) positioned to engage an outer rounded rod surface. In one embodiment, the studs (16) are oriented radially inward toward a longitudinal axis defined by the rod engaging surface (12). The rod engaging surface (12) of the jaw (16) may have a concave shape in its lengthwise direction, thus being adapted to grasp a cylindrical member such as a rod or pipe section. A tool (69) for gripping a rod including a pair of jaws (10) is also provided.</p> |
