The Milwaukee 18-Volt Cordless Li-Ion 1/2-Inch Hammer Drill comes with a convenient storage case and is compatible with long-running 18-volt Li-Ion rechargeable batteries. Milwaukee 18-volt Li-Ion equipped tools provide up to 50-percent longer run times than 18-volt Ni-Cad equipped tools, while at the same time offering "fade-free" power until the battery is completely drained. The hammer drill comes standard with an all-metal, single-sleeve, ratcheting chuck with carbide jaws to prevent bits from falling out or slipping. A comfortable non-slip, soft-grip handle reduces vibration and fatigue, and the drill comes with a side handle for added drilling/driving stability.
