Abstract
A shift bracket can be mounted on a shift rod for movement between a first, high-speed drilling mode and a second, low-speed drilling mode. Cooperating shift lock surfaces can be associated with the shift bracket and the shift rod, respectively. For example, a groove in the can create a shift lock surface on the shift rod. The shift bracket can be moved into a locked configuration where the cooperating shift lock surfaces can engage each other preventing movement of the bracket out of the high-speed drilling mode. The hammer mode can correspond to the high-speed drilling mode, but not to the low-speed drilling mode. A spring member can bias the bracket toward the locked position. An actuation member can be coupled to the shift bracket to overcome the biasing member and to rotate or perpendicularly move the bracket into an unlocked position. The actuation member can also move the shift member from the first mode to the second mode.
