The M18 FUEL™ 1/4 in. hex impact driver features a POWERSTATE™ brushless motor that delivers 0-3, 000 RPM and 0-1,800 in-lbs of fastening torque with constant power output under heavy load to drive screws faster. REDLINK Plus™ intelligence is the most advanced electronic system on the market, preventing damage to the tool and battery caused by overloading or overheating. REDLITHIUM™ Batteries deliver more work per charge and more work over the life of the pack than competitive batteries on the market. 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-KEY™ mobile amp 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. Your custom profiles are also saved in the cloud so that they can be accessed at any time. Reconditioned product.
