No matter the fastener, Milwaukee’s® M18™ Cordless REDLITHIUM™ 2-Tool Combo Kit has the tool for driving it in. The matching pair of drivers shares a set of REDLITHIUM batteries with power level gauges to keep you working all day long on a single charge. Grab the 1/4-inch hex Milwaukee impact driver for lag bolts and other big fasteners that need the 1400 inch-lbs. of torque it produces. When hanging drywall with screws instead, the 1/2-inch compact driver does a fantastic job of drilling pilot holes and anchoring the threads with 400 inch-lbs. of torque while weighing only 4 lbs. Both the Milwaukee impact driver and the compact driver produce amazing power without draining their batteries because of the frameless motors hidden inside.
