A cordless drill and impact driver kit can look like a simple two-tool purchase, but the meaningful choice is usually between keeping the listed price low, choosing a specific battery setup, or selecting a motor design that matches the work you expect to do. This group spans compact 21V kits and DEWALT 20V MAX combinations, so it helps to decide which of those priorities comes first.
Quick take
The two 21V options occupy the low end of the listed-price range, while the two DEWALT 20V MAX kits are positioned well above them. The 21V Cordless Hammer Drill Set Electric Impact Driver Screwdriver & 1/2 Battery is the lowest-priced choice and emphasizes compact, lightweight handling. The Cordless Brushless Impact Driver Hammer Drill Combo Kit with 2 Battery & Charger adds a named brushless configuration and 2.0 Ah battery specification.
Among the DEWALT choices, the DEWALT DCK277D2 20V MAX Brushless Cordless Drill Impact Driver Combo Kit New is the brushless option. The DEWALT DCK240C2 20V MAX Cordless Drill Impact Driver Combo Kit 1.3Ah New uses a brushed motor and states a 1.3 Ah battery setup.
Listed-price comparison
| Cordless kit | Listed price | Relative price position |

| DEWALT DCK277D2 20V MAX Brushless Cordless Drill Impact Driver Combo Kit New | USD 136.51 |
The listed spread runs from $18.93 to $136.51. That makes this less about choosing between nearly identical kits and more about matching the listed configuration to your planned drilling and fastening work.

Product notes
Cordless Brushless Impact Driver Hammer Drill Combo Kit with 2 Battery & Charger
This kit is a practical fit when you want a cordless hammer-drill and impact-driver combination that names two batteries and a charger in the title. Its specifications identify a 2.0 Ah lithium-ion battery, a 3/8-inch keyless chuck, and a one-hour charging time. The description also calls out included wrench sockets, drill bits, and screwdrivers, giving the set a broad accessory-focused angle. Choose it for jobs that benefit from a compact kit with drilling, driving, and hammer-drill functions represented in one package. The main tradeoff is price placement: at USD 19.99, it sits just above the lowest listed option in this group.
21V Cordless Hammer Drill Set Electric Impact Driver Screwdriver & 1/2 Battery
The 21V Cordless Hammer Drill Set is the clearest pick for shoppers prioritizing the lowest listed price, at USD 18.93. Listed features include an auxiliary handle, a keyless chuck, lithium-ion battery technology, and compact, lightweight construction. That combination makes the kit especially relevant when easier handling is central to the decision. The yellow-and-black 21V set also carries a one-hour charging-time specification. Its limitation is that charging interval: it is worth choosing for planned drilling and driving sessions where a one-hour charge cycle works naturally with the way you use cordless tools.
DEWALT DCK277D2 20V MAX Brushless Cordless Drill Impact Driver Combo Kit New
The DEWALT DCK277D2 is the brushless-motor selection in this comparison, and its title clearly identifies the 20V MAX drill and impact-driver format. It includes two batteries according to the listed attributes, and the description specifies an impact-driver torque rating of up to 1,700 in-lbs. Choose this kit when a brushless DEWALT combo is the key requirement and a two-battery configuration matters to your setup. At USD 136.51, it is the highest-priced kit here, so its listed motor type and 20V MAX configuration need to be the reasons that matter most to your decision.
DEWALT DCK240C2 20V MAX Cordless Drill Impact Driver Combo Kit 1.3Ah New
The DEWALT DCK240C2 offers a 20V MAX, two-tool format with two batteries and a stated 1.3 Ah battery configuration. Its description identifies the included DCD771 drill and DCF885 impact driver, along with a two-speed drill gearbox and 1/2-inch single-sleeve chuck. Choose it when that specific DEWALT drill-and-impact-driver combination is more relevant than a brushless motor. Its listed motor type is brushed, creating the main distinction from the DCK277D2. The USD 119.91 listed price places it between the low-price 21V kits and the brushless DEWALT option.
Final recommendation by use case
Choose the 21V Cordless Hammer Drill Set Electric Impact Driver Screwdriver & 1/2 Battery if the lowest listed price and compact, lightweight format lead your decision. Choose the Cordless Brushless Impact Driver Hammer Drill Combo Kit with 2 Battery & Charger for its named two-battery-and-charger package and accessory-oriented set. Pick the DEWALT DCK277D2 when the listed brushless 20V MAX configuration is your priority. Select the DEWALT DCK240C2 when its 1.3 Ah DEWALT two-tool setup better matches what you need.
