Abstract

A rotary power tool operable in either an impact mode or a drill mode comprising a driveshaft (10), an output shaft (32), a hammer (18) coupled to the driveshaft (10) for transmitting torque to the output shaft (32), and a blocking member (40, 74) which is in a first position wherein it blocks the hammer (18) from moving axially along the rotational axis (37) of the tool when the power tool operates in the drill mode and is in a second position wherein it allows the hammer (18) to move axially along the rotational axis (37) of the tool when the power tool operates in the impact mode, wherein the blocking member (40, 74) is supported by the driveshaft (10).
