A handheld 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 measurements exceeding the maximum current threshold.
