Offering first-rate performance and durability along with exceptional ergonomics, the DEWALT DC820B 18-volt, 1/2-inch cordless impact wrench is an ideal for driving fat lag screws or loosening large, corroded nuts. The 1/2-inch-drive, variable-speed impact wrench delivers both rotation (0-2,400 RPM) and concussive blows (0-2,700 BPM) directly to the fastener for an impressive 1,740 inch-pounds of turning force. It's powered by DEWALT's 18-volt cordless batteries (not included).

Power and Performance

Ideal for heavy-duty jobs, the DC820B delivers 1,740 inch-pounds of torque and makes quick work of fastening jobs, and its heavy-duty impacting mechanism directs torque to the fastener without kickback. The DC820B has no load speed 0-2,400 RPM and a 0-2,700 impact minimum for faster application speed. Its 1/2-inch drive is square with detent pin retention.

Dependable, the DC820B includes a frameless motor with replaceable brushes--a money-saving design that also simplifies maintenance. It also features an all-metal transmission to ensure a long life.

Comfort and Convenience

Weighing in at just 2.2 pounds and measuring just 5-3/4 inches, this compact tool can get into tight spaces other models can't access when performing a range of applications. In addition, it offers an anti-slip grip that sits well in your hand for sustained on-the-job comfort. As user-friendly as it is powerful, the DC820B features the convenience of a built-in LED light, onboard bit storage, as well as a heavy-duty, magnesium gear case.
