A handheld punch tool includes a housing, a die holder coupled to the housing, a die supported by the die holder, the die and the die holder defining a feed slot therebetween for receiving a workpiece to be cut, a punch configured to reciprocate within the die holder along a punch axis, an electric motor disposed within the housing and having a motor shaft configured to rotate about a motor axis to reciprocate the punch, and a flywheel mass coupled for co-rotation with the motor shaft about the motor axis.

Handheld punch tool

A power tool includes a soft-stop transmission having a first component and a second component. The first component is configured to receive torque from a motor to rotate the first component in a first rotational direction. The second component is connected to an output of the power tool and is configured to rotate in a first rotational direction in unison with the first component. The second component is configured to rotate in the first rotational direction relative to the first component in response to angular deceleration of the first component. A damping element is positioned between the first component and second component, and the damping element is configured to bias the first component in the first rotational direction and the second component in an opposite, second rotational direction.

Power tool including soft-stop transmission

A handheld punch tool includes a housing, a die holder coupled to the housing, a die supported by the die holder, the die and the die holder defining a feed slot therebetween for receiving a workpiece to be cut, and a punch configured to reciprocate within the die holder, with a main body defining a first longitudinal axis extending centrally through the main body and a punch element extending from the main body along a second longitudinal axis parallel to the first longitudinal axis. The punch element is configured to cut a first distance into the workpiece per stroke of the punch when the feed slot faces a first side of the punch and to cut a second distance into the workpiece per stroke when the feed slot faces a second side of the punch opposite the first side. The first distance is greater than the second distance.
