Counter-torque driver tool
One or more techniques and/or systems are disclosed for a tool driver device that can apply counter-torque to the device while applying torque to a target component that is engaging a target base. The example device can be operated by one hand to actuate a power input component that provides the desired torque, while providing counter-torque to offset rotation of the device.

A power input provides power to apply rotational force to drive a selectably coupled tool, which has been selected to complement the target component engaged with a target base. The counter-torque component is operably engaged with the base, which applies counter-torque to the torque provided by the target component.
