Choosing between cordless power tools often comes down to one practical question: do you need a hammer drill on its own, or a ready-to-use drill/driver kit? The DEWALT DCD805 MAX XR 20V Hammer Drill Driver and DEWALT DCD771C2 20V MAX Drill/Driver Kit take those different approaches. One emphasizes hammer-drilling capability in an only-tool format; the other centers on a multi-piece kit for drilling and fastening.
Quick verdict
Pick the DEWALT DCD805 MAX XR 20V Hammer Drill Driver when hammer-drill capability, a 1/2-inch keyless chuck, and the lower USD 52.49 price are the priorities. Its only-tool format suits shoppers who specifically want the drill itself rather than a bundled setup.
Choose the DEWALT DCD771C2 20V MAX Drill/Driver Kit if having two batteries, a charger, and a contractor bag in the set matters more. At USD 99.00, it costs USD 46.51 more and is positioned around a compact two-speed drill/driver setup.

Where each product wins
DCD805 wins for hammer-drill tasks and a standalone-tool purchase. Its hammer drill driver designation makes it the direct choice for shoppers who want that mode called out in the tool name. The keyless chuck and stated up-to-330-in-lb torque further support its focus on drilling and fastening work.
DCD771C2 wins for an all-in-one drill/driver set. Two batteries, a charger, and a contractor bag are included, so the kit has a broader out-of-box collection of components. Its two-speed transmission also gives it clearly stated low- and high-speed ranges for drilling and fastening.
Product notes
DEWALT DCD805 MAX XR 20V Brushless Cordless 1/2-inch Hammer Drill Driver
At USD 52.49, the DCD805 is the lower-priced choice and the more direct fit for someone seeking a cordless hammer drill driver rather than a kit. The brushless motor, 1/2-inch keyless chuck, and hammer-drill function give it a focused feature set for drilling and fastening projects. Its stated torque of up to 330 in-lb is another useful specification for shoppers comparing standalone tools. The tradeoff is straightforward: this is an only-tool configuration, and no battery is included. It also lists no auxiliary handle, which may matter for shoppers who specifically want that feature included with their drill.
DEWALT DCD771C2 20V MAX Cordless Drill/Driver Kit
The DCD771C2 is built around kit completeness: it includes two batteries, a charger, and a contractor bag alongside the drill/driver. Its compact, lightweight design and two-speed transmission-0-450 and 0-1,500 RPM-make its intended drilling-and-fastening role clear. An auxiliary handle is also included in its feature list. Choose this set when those bundled components are central to the purchase. The limitation is the USD 99.00 price, which is USD 46.51 higher than the DCD805. It is also presented as a drill/driver kit rather than with the DCD805's hammer-drill designation.
Final choice by use case
Choose the DCD805 for a hammer drill driver in an only-tool format, especially when the 1/2-inch keyless chuck and stated torque are more important than included accessories. Choose the DCD771C2 for a compact drill/driver kit when two batteries, a charger, a bag, and two-speed operation better match the work you plan to do. The deciding factor is not simply tool price: it is whether hammer-drill functionality or a bundled drilling-and-fastening kit better suits your setup.
