DEWALT DCK2050M2 Hammer Drill Combo Kit vs DeWalt 20V Max 5-Tool Combo Kit

Buy the DCK2050M2 if you want the strongest drill and driver: the XR hammer drill adds masonry drilling and the ATOMIC impact driver is compact with high torque, backed by 4.0Ah batteries. Buy the DCKSS521D2 if you are outfitting a shop and need more tools: it adds a multi-tool, orbital sander and work light, but the drill is a plain drill/driver, the batteries are smaller 2.0Ah, and it has far fewer owner ratings. On build, both are brushless DeWalt 20V MAX with bags; the two-tool kit is the better core, the five-tool kit is the better spread.

• Choose the DCK2050M2 if you drill concrete or masonry, drive large screws, and want two 4.0Ah batteries in a compact two-tool kit.
• Choose the DCKSS521D2 if you want five tools in one box, including a multi-tool, sander and work light, and can live with 2.0Ah batteries.
