The MILWAUKEE M18 Brushless 1/4" Hex Impact Driver is the fastest 18V compact impact solution in it's class. The brushless motor technology is optimised for the driver, providing 180Nm of torque and longer runtime. The motor designed designed for this impact driver delivers a smaller tool at 129mm, extends battery life and greatly improves access to small and tight spaces. Built-in REDLINK electronics optimise the power draw from the REDLITHIUM™ batteries, delivering 3,400 RPM's for best in class application speed and performance. 3-Mode DRIVE CONTROL delivers unmatched control for a wide range of small and large applications. The impact driver also has single-handed bit insertion for easy bit exchange. The Brushless 1/4" Hex 3 Speed Impact Driver works with all M18 batteries so you can work harder for longer.
