The M18 FUEL 1/4" hex impact driver is the most powerful tool in its class. This hex impact driver provides up to 3X longer motor life, 50% more runtime, and proprietary Milwaukee® 3-Mode DRIVE CONTROL for better control over the power and speed required for specific applications. The POWERSTATE brushless motor outperforms all leading competitors with constant power output, yet runs cooler with no wearable components. The REDLITHIUM extended capacity battery pack delivers more work per charge and more work over pack life than the competitors, as well as best-in-class performance in extreme jobsite conditions. The onboard fuel gauge helps you monitor the charge more accurately, so there's less downtime on the job. REDLINK PLUS intelligence ensures optimized performance and protection from overload, overheating and over-discharge. The M18 FUEL 1/4" hex impact driver offers up to 55% faster application speed, and a range of 200 - 1600"-lb of torque. Its compact size and weight allow access to tighter areas and reduce user fatigue. The built-in LED light illuminates work surfaces in dark locations. The kit includes the new multi-voltage charger, so you can charge all M12 and M18 lithium-ion batteries with one charger.
