Systems and Methods for Automatically Adjusting a Power Tool Setting Based on Power Tool Device Positioning Relative to a Work Object
One or more settings of a power tool device can be automatically adjusted based on a location of the power tool device relative to a work object. Work object data that indicate a work object type for the work object can be determined, and work location data can be determined based on the work object data. The work location data indicate work locations on the work object where a power tool device action is to be performed. A position of the power tool device is also determined. An electronic controller can determine a power tool device setting corresponding to the power tool device action to be performed at the work location nearest to the power tool device position. The power tool device setting is transmitted to the power tool device by the electronic controller, where the power tool device setting indicates an operating parameter of the power tool device.

Power tool having multiple operating modes
A hand-held power tool is configured to receive an input indicative of a clutch setting for an electronic clutch from the tool operator, where the clutch setting is selectable from a drill mode, an automated drive mode and one or more user-defined drive modes. Each of the user-defined drive modes specifies a different value of torque at which to interrupt transmission of torque to the output spindle. In an automated drive mode, the controller interrupt torque to the output spindle in an automated manner when a fastener being driven reaches a desired stopping position. In a selected one of the user-defined drive modes, the controller sets a value of a maximum current threshold in accordance with the selected one of the user-defined drive modes and interrupts torque to the output spindle when current measures exceeding the maximum current threshold.
