Abstract

A hammer drill bit chuck attachment comprises a main shaft having a forward drill chuck end portion and a rearward shank portion, and defining a longitudinal axis. An impact member is mounted in fixed relation on the main shaft for rotation therewith. An actuator mechanism is mounted on the main shaft for free rotation of the main shaft with respect to the actuator mechanism and for longitudinal sliding movement of the actuator mechanism along the main shaft between a forwardly displaced position and a rearwardly displaced position. Αt least one impact portion is disposed on one of the impact member and the actuator mechanism. At least one roller member is rotationally mounted on the other of the impact member and the actuator mechanism. Rotation of the main shaft and impact member about the longitudinal axis when the actuator mechanism is in force transmitting engagement with the impact member, causes the actuator mechanism to move in a reciprocating motion between the forwardly displaced position and the rearwardly displaced position, and transmits impact forces forwardly along the longitudinal axis to the main shaft.
