Abstract

A hammer-action attachment for use with an electric drill comprises a main shaft with an impact member mounted in longitudinal force transmitting relation on the main shaft for rotation therewith. An actuator mechanism is mounted on the main shaft for free rotation and for longitudinal sliding movement between a forwardly displaced position and a rearwardly displaced position. A drill engaging member is securely connected to the actuator mechanism and extends rearwardly to engage an electric drill. The drill engaging member biases the actuator mechanism into force transmitting engagement with the impact member, and precludes rotational movement about the longitudinal axis of the actuator mechanism with respect to the drill. Rotation of the main shaft and impact member causes the actuator mechanism to move in a reciprocating motion between the rearwardly displaced position and the forwardly displaced position, and transmits impact forces forwardly along the longitudinal axis to the main shaft.
