ONE-KEY enabled, this is the industry's first impact driver that wirelessly connects to a smart phone to provide unlimited customization and control of the tool's performance. The ONE-KEYMobile app features predetermined set-ups for specific fasteners and materials, or provides complete control over output speed and power to customize the tool for the specific application at hand. Once the desired output performance is reached, the custom profile is then saved to the memory of the tool and the connection to the smart phone is no longer necessary. The tool's memory supports up to 4 custom profiles that can be easily accessed with the touch of a button on the tool.
