A patented battery isolation system manages high frequency vibrations, enabling battery movement that prevents damage and ensures a constant connection between the battery and tool when in use. The 4-Mode DRIVE CONTROL provides greater control over the output speed and power of the High Torque Impact Wrench. The ONE-KEY Technology allows for customization, tracking, and management of the impact wrench with the ability to set a repeatable torque output for maximum control.
