A cordless drill and impact-driver kit decision is about more than getting two tools in one bag. Motor design, battery capacity, fastening torque, and drill controls can point shoppers toward different DEWALT 20V MAX combinations. The DEWALT DCK240C2 and DEWALT DCK277D2 both cover drilling and driving, so the useful question is which configuration better suits the priorities of your work.
Quick verdict
Pick the DCK240C2 when a drill with specifically stated speed ranges and a 1/2-inch chuck answers the job. Favor the DCK277D2 when a brushless motor is the decision point. The two kits share the DEWALT 20V MAX lithium-ion platform, while their listed battery capacities and impact-driver torque figures create the more meaningful divide.
Listed comparison
| Kit | Listed price | Motor | Included batteries | Listed maximum impact-driver torque |

The listed price spread is USD 16.60.
Where each kit wins
DCK240C2 pulls ahead on listed price and specified drill controls
The DCK240C2 sits at the lower end of the USD 16.60 listed-price spread. Its DCD771 drill has a two-speed gearbox rated at 0-450 and 0-1,500 RPM, plus a 1/2-inch single-sleeve chuck. The DCF885 impact driver is listed at 0-2,800 RPM and 0-3,200 IPM. That combination gives shoppers who want clearly stated speed and chuck specifications a direct reason to focus on the DCK240C2.
DCK277D2 pulls ahead on battery capacity and torque figures
The DCK277D2 lists two 2.0Ah compact lithium-ion batteries and up to 1,700 in-lbs of impact-driver torque, compared with two 1.3Ah batteries and up to 1,400 in-lbs for the DCK240C2. The difference is in the stated battery-capacity and torque figures, not a change in the shared 20V MAX lithium-ion platform. Select the DCK277D2 when those larger listed figures are central to the kit choice.
