REVERSING HAMMER DRILL ABSTRACT OF THE INVENTION A hammer drill having a bypass switch which is activated by the selector ring to prevent the drill from operating in the hammer mode by shunting the reversing switch. This is a precaution to prevent damage to the clutch teeth which are designed for ratchet action when the tool is operated in the for- ward direction, but will lock down in reverse to stall tool or damage the mechanism. In the drill mode, the bypass switch connects the reversing switch in circuit with the on-off switch.
