An impact tool includes a rotational energy device mounted within the housing of the tool. A driver is reciprocally mounted within the housing and is coupled to the energy device by a toggle member. The toggle member includes a clutch and is actuated to transfer energy from the energy device to the driver. The driver and toggle are driven through a power stroke upon engagement of the clutch with the energy device. Upon completion of the power stroke, the clutch engages a bumper removing the clutch from the energy device and the toggle and driver are returned by a return assembly driven by the energy device.
