The M18 FUEL ONE-KEY 2 Piece Power Pack 2B includes the M18 FUEL 13mm Hammer Drill with ONE-KEY (M18ONEPD-0) and the M18 FUEL 1/2" Impact Wrench with ONE-KEY (M18ONEIWF12-0). M18 FUEL features the most advanced cordless technology available; a POWERSTATE Brushless Motor, REDLINK PLUS Electronic Intelligence and REDLITHIUM Battery Technology, resulting in longer motor life, more runtime and more power. Both tools are ONE-KEY enabled, allowing users to wirelessly connect to the tool with a smart phone to provide unlimited customisation and control of the tool’s performance. The ONE-KEY Mobile app features predetermined set-ups for specific fasteners and materials, or provides complete control over output speed and power to customise 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. Your custom profiles are also saved in the cloud so that they can be accessed at any time.
