Abstract: 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.

Abstract: A power tool includes a housing, a motor positioned within the housing, an output shaft driven by the motor, the output shaft configured to be coupled to an accessory for operation thereof, a sensing circuit configured to detect, during operation of the power tool, an operating characteristic of the motor, and a controller. The controller is configured to receive a signal from the sensing circuit representing the operating characteristic of the motor, compare the operating characteristic of the motor to a first predetermined threshold, and in response to the operating characteristic exceeding the predetermined threshold, perform a loss of control check on the power tool. Performing the loss of control check includes comparing a detected motion of the power tool to a second predetermined threshold, and tripping loss of control functionality based on whether the detected motion of the power tool exceeds the second predetermined threshold.

Abstract: An angle grinder including a motor housing, a motor supported within the motor housing, a spindle, a spindle housing from which the spindle extends, and a guard coupled to the spindle housing and including a shroud surrounding the spindle and a grinding disc coupled to the spindle. An orientation of the guard is adjustable relative to the spindle housing by rotating the guard about a rotational axis of the spindle. The angle grinder also includes a locking mechanism operable between a locking state, in which the guard is rotationally immovable relative to the spindle housing, and a release state, in which the guard is rotatable about the rotational axis to adjust the orientation of the guard. The locking mechanism includes a lever configured to be pressed by a user to adjust the locking mechanism from the locking state to the release state.
