The Milwaukee 0726 Cordless LITHIUM-ION 28 Volt 1/2 in. Hammer-Drill uses the Milwaukee built high power motor to develop an enormous 750 in. lbs. of maximum torque and 0-450/0-1800 rpm, ideal for drilling larger holes and driving larger screws faster. Powering the 0726 is the revolutionary 28 Volt LITHIUM-ION battery pack exclusively from Milwaukee. The 0726 comes standard with a 1/2 in. all-metal, single-sleeve, ratcheting chuck with all carbide jaws that keeps bits from falling out and drill bits from slipping. A comfortable non-slip, soft-grip handle reduces vibration and fatigue.
