    Abstract: Systems and methods for detecting and acting on bind-up conditions of a power tool. The power tool includes a housing, a motor, a battery pack, and a motion sensor configured to sense rotational motion of the housing. An electronic controller is connected to the motor, the battery pack, and the motion sensor. The electronic controller is configured to determine whether a battery fetting event is occurring and adjust a rotational motion threshold used to determine a bind-up event based on the battery fetting event. The electronic controller is further configured to receive, from the motion sensor, a first signal associated with a rotational motion of the housing, compare a value based on the signal to the rotational motion threshold, and initiate, in response to the value being greater than or equal to the rotational motion threshold, a protective operation.

    Abstract: A device for performing a function. The device including a housing, an indicator configured to provide an indication, a first electronic processer within the housing and configured to control operation of the indicator, and a wireless communication device including a second electronic processer. The wireless communication device is configured to wirelessly communicate with an external device, communicate with the first electronic processer to transfer data between the first electronic processer and the external device, receive a signal from the external device, and provide the signal to the first electronic processer. The first electronic processer is configured to prohibit, in response to receiving the signal from the wireless communication device, the indicator from providing the indication.

    Abstract: An attachment is configured for use with a powered hammer to drive a rod into the ground. The attachment includes a body and an impact portion defining a first axis. The impact portion is fixed to the body and immovable relative to the body. The impact portion is configured to receive repeated impacts from the powered hammer. The attachment further comprises a receiving portion in which the rod is receivable. The receiving portion defines a second axis that is parallel with the first axis.

    Abstract: A multi-size tool bit holder includes a first sleeve having a first bit holding bore extending along an axis, and a second sleeve coupled for co-rotation with the first sleeve and movable relative to the first sleeve between a first position and a second position. The second sleeve includes a second bit holding bore. A first bit shank of a first nominal size is insertable into the first bit holding bore when the second sleeve is in the second position to secure the first bit shank within the first sleeve. A second bit shank of a second nominal size different than the first nominal size is insertable into the second bit holding bore when the second sleeve is in the first position to secure the second bit shank within the second sleeve.

    Abstract: Devices and methods for automatically controlling a step bit operation in a power tool. The method includes generating, by a sensor of the power tool, sensor data indicative of an operational parameter of the power tool wherein a step bit is coupled to the power tool. An electronic control assembly of the power tool receives the sensor data, where the electronic control assembly includes an electronic processor and a memory. The memory stores a machine learning control program for execution by the electronic processor. The electronic control assembly processes the sensor data using a machine learning control program of the electronic control assembly and generates, using the machine learning program, an output based on the sensor data. The output indicates step bit progress information. The electronic control assembly controls a motor supported by the housing of the power tool based on the output.

    Abstract: Kickback control methods for power tools. One power tool includes a movement sensor configured to measure an angular velocity of the housing of the power tool about the rotational axis. The power tool includes an electronic processor coupled to the switching network and the movement sensor and configured to implement kickback control of the power tool. To implement the kickback control, the electronic processor is configured to control the switching network to drive the brushless DC motor, receive measurements of the angular velocity of the housing of the power tool from the movement sensor, determine that a plurality of the measurements of the angular velocity of the housing of the power tool exceed a rotation speed threshold, and control the switching network to cease driving of the brushless DC motor in response to determining that the plurality of the measurements of the angular velocity exceed the rotation speed threshold.
