The wrench comprises a body portion which seats on and connects to the top of an auger section, a slip jaw riding in an inclined jaw guide and extending through the wrench body wall, and a pair of pipe gripping jaws at the top of the wrench body. One of those jaws is fixed to the wrench body while the other is relatively movable so as to releasably grip a drill rod passing therebetween.
