Abstract
A drill rod clamping device that is configured to clamp and secure drill rods, such that a drill rod of any diameter can be secured in the center of the device. The drill rod clamping device includes a pair of opposing jaws and either a back jaw or a locator block to ensure desired positioning of the drill rod relative to the drill rod clamping device. An actuating assembly selectively moves the opposing jaws toward each other and away from each other such that both of the opposing jaws move at substantially the same speed.
