Choosing cordless power tools gets complicated when the package matters as much as the drill itself. An included battery can make a set ready for a different kind of purchase than a tool-only model, while chuck size, charging time, and handle configuration help separate four otherwise similar-looking options. Start with the package format you need, then narrow by the specific drilling or driving details that matter to your work.
Quick take
Three choices include a lithium-ion battery: the compact 21V Cordless Hammer Drill Set, the Cordless Brushless Impact Driver Hammer Drill Combo Kit, and the 20V Cordless Harmmer Drill. The DEWALT DCD805 takes the other route as a brushless 20V tool-only cordless impact drill driver.
For an auxiliary handle and compact, lightweight callout, focus on the 21V Cordless Hammer Drill Set. The combo kit stands out for its title-listed two batteries and charger plus a 2.0 Ah battery capacity. The 20V Cordless Harmmer Drill brings a 1/2-inch chuck and included 1.5 Ah battery, while the DCD805 is the pick for a tool-only package with variable speed and an LED light.
Listed-price comparison
The listed range runs from USD 18.93 to USD 48.99, a USD 30.06 spread. Package contents and tool configuration account for much of the decision here, so compare the price alongside the included-battery versus tool-only distinction.
| Power tool | Listed price | Price position |
|---|---|---|
| 21V Cordless Hammer Drill Set Electric Impact Driver Screwdriver & 1/2 Battery | USD 18.93 | |
| Cordless Brushless Impact Driver Hammer Drill Combo Kit with 2 Battery & Charger | USD 19.99 | |
| 20V Cordless Harmmer Drill 1/2"in Brushless Electric Impact Wrench With Battery | USD 41.89 | |
| DEWALT DCD805 20V Brushless Cordless Impact Drill Electric Screwdriver Only | USD 48.99 |
Decision matrix
- Choose the 21V Cordless Hammer Drill Set when an included lithium-ion battery, auxiliary handle, keyless chuck, and compact build are your priorities.
- Choose the Cordless Brushless Impact Driver Hammer Drill Combo Kit when the two-battery-and-charger package, 2.0 Ah capacity, and 3-in-1 hammer, driver, and drill modes fit your needs.
- Choose the 20V Cordless Harmmer Drill when a listed 1/2-inch chuck and included 1.5 Ah battery matter more than a faster charging time.
- Choose the DEWALT DCD805 when you specifically want a brushless 20V cordless impact drill driver in a tool-only configuration with a variable-speed trigger and built-in LED light.
Product notes
21V Cordless Hammer Drill Set Electric Impact Driver Screwdriver & 1/2 Battery
The 21V Cordless Hammer Drill Set is a direct fit for shoppers seeking a compact setup with an included lithium-ion battery and an auxiliary handle. A keyless chuck and one-hour charging time keep the core setup straightforward, and the compact, lightweight feature callout gives this yellow-and-black option a distinct focus. It is also positioned at the low end of the listed-price range. The limitation is its package format: with a battery included, it is not the tool-only configuration represented by the DEWALT DCD805. Pick it for an included-battery 21V set where the auxiliary handle and compact format are central.
Cordless Brushless Impact Driver Hammer Drill Combo Kit with 2 Battery & Charger
This Cordless Brushless Impact Driver Hammer Drill Combo Kit makes sense when the kit contents are the deciding factor. Its title specifies two batteries and a charger, while the battery capacity is listed as 2.0 Ah. The description also names hammer, driver, and drill working modes, a 25+1 position clutch, a soft-grip handle, an electronic brake system, and a trigger-activated LED light. Its one-hour charging time matches the 21V Cordless Hammer Drill Set. The clear tradeoff is the listed 3/8-inch keyless chuck, which is smaller than the 1/2-inch chuck listed for the 20V Cordless Harmmer Drill.
20V Cordless Harmmer Drill 1/2"in Brushless Electric Impact Wrench With Battery
Select the 20V Cordless Harmmer Drill when the listed 1/2-inch chuck is more important than a smaller 3/8-inch chuck. This red-and-black cordless option includes a 1.5 Ah lithium-ion battery and is presented in its title as a brushless electric impact wrench. Its configuration differs from the 21V Cordless Hammer Drill Set because it is explicitly listed without an auxiliary handle. Charging time is the main constraint: it is listed at two hours, compared with one hour for both the 21V Cordless Hammer Drill Set and the Cordless Brushless Impact Driver Hammer Drill Combo Kit. It suits a shopper prioritizing the 1/2-inch chuck and included battery.
DEWALT DCD805 20V Brushless Cordless Impact Drill Electric Screwdriver Only
The DEWALT DCD805 is the clear match for someone intentionally shopping for a tool-only cordless impact drill driver. Its listed 20V brushless motor, compact and lightweight design, variable-speed trigger, ergonomic grip, and built-in LED light focus the choice on the bare tool rather than an included battery package. The description also identifies construction, installation, woodworking, DIY, home repair, workshop, and garage use. Its key limitation is explicit: neither a battery nor charger is included. That makes it materially different from the three battery-included alternatives, particularly if your immediate need is a complete drill-and-battery package rather than the DCD805 itself.
Final recommendation by use case
Choose the 21V Cordless Hammer Drill Set for an included-battery compact tool with an auxiliary handle. Choose the Cordless Brushless Impact Driver Hammer Drill Combo Kit for the two-battery-and-charger package and 3-in-1 modes. Choose the 20V Cordless Harmmer Drill when its 1/2-inch chuck is the key specification. Choose the DEWALT DCD805 only when the brushless, 20V tool-only format aligns with the batteries and charger you plan to use.
