Abstract: A portable electric knockout punch comprising: an electric motor; a hole forming mechanism having a support portion for cooperating with a die and a punch portion for cooperating with a stamp wherein the hole forming mechanism is operatively coupled to the electric motor for causing axial displacement of the punch portion relative to the support portion between a home position and an active position for forming a hole in sheet metal; a home position sensor for generating output indicative that the punch portion has reached the home position during a reset stage of operation in which the punch portion is moved towards the home position; and a controller for receiving motor turn information indicative of the number of turns of the electric motor and for controlling axial movement of the punch portion in use based only on the motor turn information and the output generated by the home position sensor.

Abstract: A portable electric pressing tool comprising: an electric motor; a pressing mechanism having a pair of jaws and a driver wherein the pressing mechanism is operatively coupled to the electric motor for causing axial displacement of the driver between a home position and an active position for actuating the jaws; a home position sensor for generating output indicative that the driver has reached the home position during a reset stage of operation in which the driver is moved towards the home position; and a controller for receiving motor turn information indicative of the number of turns of the electric motor and for controlling axial movement of the driver in use based only on the motor turn information and the output generated by the home position sensor.
