Hog ring models are preferred by mechanics because they make it easier to change sockets--which tend to become stuck on detent pins.

Detent anvil models are best for those applications where it's imperative sockets don't pop off on their own--as when working high in the air or on a ladder.

DeWalt recently introduced a series of 20V MAX Brushless High Torque Impact Wrenches. The first is available with a 1/2-inch hog ring (DCF899HP2) or detent pin anvil (DCF899P2), the second with a 3/4-inch hog ring with retention pin hole anvil (DCF897P2), and the third (DCF897) with the type of 7/16-inch quick release chuck favored by utility workers.

Larger and more powerful than the impact drivers commonly used by carpenters, these impact wrenches are intended for heavy duty applications that might otherwise be performed with air tools or large corded models. I was present for the public unveiling of the new tools at an event held at the NASCAR Hall of Fame in Charlotte, NC. It was held there because it was close to the DeWalt assembly plant we were to visit the next day (for a tour of the factory and a preview of upcoming tools) and an appropriate venue for a demonstration of impact wrenches.

DeWalt is among the sponsors of Matt Kenseth’s No. 20 Toyota, and he was on hand with his pit crew from Joe Gibbs Racing. To highlight the ability of the new impact wrenches, the crew used them to remove and replace all four tires on Kenseth’s car—the same as they would at a NASCAR race. To my eyes they did it exceptionally quickly, though to them I’m sure it seemed slow. No matter, these impact wrenches are not intended for use by NASCAR pit crews, which use custom-built pneumatics that spin at 16,000 rpm; they’re intended for mechanics, construction workers, farmers, and utility workers—anyone who needs to remove or install big bolts and fasteners. And for that they work well, and without the hassle of hauling a compressor or trailing a hose or cord.

These high-torque impact wrenches have efficient, brushless motors and deliver power, speed, and excellent runtime when equipped with DeWalt’s top-of-the-line 5.0 Ah battery pack. The 1/2 Inch (DCF899) hog ring or detent pin anvil impact wrench delivers 700 ft-lbs of max torque and 1200 ft-lbs of max breakaway torque. Compact for tools of their power, these impact wrenches have LED lights and three speeds for application-specific control.
