Our take on the Dewalt DCD798B 20V MAX Brushless 1/2 in. Cordless Hammer Drill Driver (Tool Only)

The DeWalt DCD798B is a 20V MAX brushless hammer drill driver sold as a bare tool, so you need DeWalt 20V batteries and a charger you already own. Its main draw is size: the head is about 6.93 inches long, roughly an inch shorter than the previous generation, which helps between studs and in overhead work. The brushless motor is rated up to 404 UWO, 1,650 RPM in drill mode and 28,050 BPM in hammer mode, with a 1/2-inch ratcheting chuck and an LED light. It sits below DeWalt's high-torque flagship drills on raw power but competes with compact brushless hammer drills from Milwaukee and Makita on length and handling.

Pros

  • Brushless motor rated up to 404 UWO
  • Hammer mode up to 28,050 BPM for masonry

Cons

  • Not DeWalt's most powerful hammer drill
  • Compact body can limit leverage on heavy bits

What reviewers say

  • 4.2 / 524 ratings

Ratings are solid but not glowing, averaging 4.2 out of 5 from 24 ratings. Buyers tend to value the compact size and brushless power for the class; the bare-tool packaging and the limits of a compact hammer drill come up as drawbacks.

What people mention
  • SizePraisedOwners like the short head for working between studs and overhead.
  • PowerMixedThe brushless motor is seen as strong for a compact drill but short of full-size hammer drills.
  • BatteryCriticisedBuyers note it is a bare tool and needs separate 20V batteries and a charger.
  • Hammer modeMixedHammer mode is fine for light masonry but not for heavy concrete work.

About the Dewalt DCD798B 20V MAX Brushless 1/2 in. Cordless Hammer Drill Driver (Tool Only)

The DEWALT DCD798B is a 20V MAX brushless cordless hammer drill driver with a 1/2 in. ratcheting chuck. It is sold as a tool only. It is made for concrete, masonry, and everyday drilling and fastening tasks.
