If you’ve been driving in lag screws and loosening large hex nuts with a ratchet wrench, or worse still, an open-end wrench, then you’re going to love the DeWalt DW057K-2 Cordless Impact Wrench. This compact, portable powerhouse is driven by an 18-volt nickel-cadmium (Ni-Cad) battery that produces 1,650 in./lbs. of torque, and 3,000 blows-per-minute of percussive force to bust loose the most stubborn nuts, including tire lugs. This 4.9 pound cordless wrench is also invaluable for tightening hex-head machine bolts and driving long lag screws into wood.

The DW057K-2 is just 6-1/2 inches long—about the same size as a cordless drill, so it’ll work in tighter spaces than standard impact wrenches. It has a metal 1/2-inch-square detent pin anvil, which firmly holds the socket in place. Other features include a sure-grip handle, durable magnesium gear case, and an all-metal transmission for smooth operation. -- Joseph Truini
