The 18-volt half-inch DX13 Brushless Hammer Drill is a portable power tool with a Graphene battery. The 18-volt, 5.0-amp hour Graphene battery delivers twice the power, charges three times faster and provides four times longer life cycles than lithium-ion batteries. The tool exerts 700 inch-pounds of torque for heavy-duty applications. It is equipped with a half-inch ratcheting, all-metal chuck for gripping power, bit retention and shock resistance.
