The DeWalt DCD800B is a 20V MAX XR brushless cordless drill/driver built for professionals. It delivers up to 40% more Unit Watts Out than the DCD791B, spins at up to 2,000 RPM, and measures just 6.37 inches long for tight spaces. The 1/2-inch metal ratcheting chuck holds bits securely, and the three-mode LED with spotlight helps in dark areas. It suits tradespeople and serious DIYers who already own DeWalt 20V batteries; the tool-only package keeps value high for those invested in the platform. Compared with the DCD791B, it offers more power and a more compact body, though it lacks a belt hook and magnetic bit holder that some rivals include.

The DEWALT DCD800B is a 20V MAX XR brushless cordless drill/driver with a 1/2 in. keyless metal ratcheting chuck. It is sold as a tool only, so the battery and charger are not included. It is 6.37 in. long, which helps in tight spaces.
A high-output brushless motor drives the tool, and a two-speed transmission covers drilling and fastening. No-load speed is 0-650 / 0-2,000 RPM, with variable trigger control. It delivers up to 900 UWO and has 15 clutch settings.
A 3-position, 3-mode LED provides up to 70 lumens and has a spotlight mode that shuts off after 20 minutes. A pocket in the tool holds a Tool Connect chip for jobsite asset tracking. The chip is sold separately.
