Our M18™ Compact Brushless 1/4 in. Hex Impact Driver is the fastest 18v compact impact in its class. We built a brushless motor optimized for the driver that provides 1,600 in-lbs. of torque and more runtime. The compact motor also makes our compact brushless impact driver a smaller tool at 5.1 in., which means longer battery life and greatly improved access to small and tight spaces. MILWAUKEE® REDLINK™ electronics optimize the way our REDLITHIUM™ batteries work with the hardware of the impact driver, delivering 3,200 RPM's for best in class application speed and performance. Like all M18™ products, the compact brushless 1/4" hex impact driver works with all our M18™ batteries so you can work harder for longer. The kit comes with the Impact Driver, (2) M18™ REDLITHIUM™ CP2.0 compact batteries, M18™/M12™ Multi-Voltage Charger, Belt Clip and Carrying Case
