ABSTRACT:
A portable machine tool comprises a main spindle and a machine body that is rotatable relative to the main spindle. A take-off shaft is mounted in the machine body and is rotatable relative to the machine body, and a rocker arm is rotatable about the axis of the take-off shaft. A cam and follower mechanism converts rotation of the machine body to reciprocating rotation of the rocker arm, and a releasable clutch mechanism that is effective between the rocker arm and the take-off shaft can be switched between a first state in which it converts reciprocating rotation of the rocker arm to unidirectional rotation of the take-off shaft and a second state in which reciprocating rotation of the rocker arm has no effect on the take-off shaft.
