Abstract
A hand held electrically powered drilling and/or hammering tool comprises a balanced motor sub-assembly including a radial fan mounted to the armature shaft at a first end of the motor with the fan blades facing away from the motor, and motor the sub-assembly is mounted with the axis of the motor angled with respect to the axis of the tool spindle and with the first end of the motor closest to the spindle, and an air outlet is located in the housing near a second end of the motor, and the above components are arranged so that rotation of the fan draws air into its inlet via air inlets and then pushes air from its outlet through the motor and out of the air outlets in the region of the second end of the motor which is remote from the spindle axis.
