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 rotating power tool assembly includes a rotating power base and a modular drive head. The rotating power base may be configured to rotate a spindle, and the modular drive head may be configured to be detachably coupled to the rotating power base. The modular drive head may comprise a torque control clutch, a working tip, and a torque value indicia. The torque control clutch may be non-adjustably structured to implement a torque limiting slip event that prevents the working tip from further rotation, despite continued rotation of the spindle, in response to the working tip being subjected to torque in excess of a discrete torque value. The torque value indicia may be externally visible and may comprise a visible characteristic that correlates to the discrete torque value.

The rod may be inserted between the conductor and the wire tie and rotated along with the ring gear to unwind the wire tie. The rod may comprise wire bristles to abrade corrosive material off the conductor. The rotary tool may be remotely operated by a robotic unit.
