Abstract

A pullback system for a drilling tool includes features to retain a pulling cable. The drilling tool includes a drill bit body for carrying a plurality of cutting teeth. The drill bit body has a first side and an opposite second side. The drill bit body also defines a first pullback device passage that extends through the drill bit body from the first side to the second side. The first pullback device passage extends generally along a passage axis that extends through the drill bit body. The first pullback device passage includes at least a portion adjacent to the first side that curves as the surface extends in a direction along the passage axis. The passage axis is positioned along a reference plane that generally bisects the drill bit body.
