Abstract: A power tool and method of detecting impacts of a power tool that includes a motor driving a hammer to impact an anvil. A motor control unit is configured to determine a motor characteristic indicative of a speed of the motor. When the motor characteristic indicates that the speed of the motor is below a speed threshold, the motor control unit employs an acceleration-based technique to detect a first impact based on a change in motor acceleration and generate a first impact indication in response to detecting the first impact. When the motor characteristic indicates that the speed is above the speed threshold, the motor control unit employs a time-based technique to detect a second impact based on an elapsed time and generates a second impact indication in response to detecting the second impact.

Abstract: A cutting tool includes a housing and a pair of cutting blades at least partially extending from the housing. At least a first of the cutting blades is movable. The cutting tool also includes a drive mechanism including a cam and a ratchet mechanism. At least a portion of the ratchet mechanism is drivably coupled to the first cutting blade. The cutting tool further includes a motor for providing torque to the cam to actuate the ratchet mechanism. The ratchet mechanism includes a follower that is translatable in a direction transverse to a rotational axis of the cam in response to rotation of the cam.

Abstract: A power tool and a method of operating a power tool including a motor, a clutch collar including a plurality of settings, a wireless transceiver operable to form a wireless connection with a remote device, and a processor coupled to the clutch collar and the wireless transceiver. The processor receives, via the wireless transceiver, a mapping including a plurality of torque levels corresponding to the plurality of settings. The processor detects that the clutch collar is set to a setting of the plurality of settings. The processor is further determines the torque level for the setting from the mapping and detects, during the operation of the power tool, that a torque of the power tool exceeds the torque level. The processor is also configured to generate an indication that the torque exceeds the torque level. The indication may include flashing a light, ratcheting the motor, and stopping the motor.
