The Rockwell 18-Volt LithiumTech Drill/Driver is performance and efficiency in a cordless drill. This drill/driver utilizes LithiumTech battery technology to put long-lasting, powerful performance at your fingertips. This all-purpose drill is also durable, lightweight, and easy to manage so you can get more done in less time with less fatigue. With the included two LithiumTech batteries, there is no memory effect so batteries can be charged and remain useful while waiting, unlike standard Ni-Cd batteries that lose charge. These batteries also weigh 40% less than standard Ni-Cd batteries, yet can be charged up to three times more cycles than standard Ni-Cd batteries and offer 50% higher capacity. Moreover, unlike ordinary Ni-Cd and Ni-MH batteries that lose their power rapidly, LithiumTech batteries will hold their charge even after months of inactivity. At just 4.2 pounds, this cordless drill packs a powerful punch in a small package. It provides 22 torque settings with 450 in.-lbs of torque. To ensure optimum precision this drill/driver offers high and low gears with a variable speed range of 0-400/0-1300 rpm, which makes it easy to match the correct speed to the task at hand. It also has a half-inch-sleeve metal chuck for durability, and a comfort grip handle for extended use and control.
