The best brushless drill kit for you depends on the battery system you want, the space you need to reach and whether you need hammer drilling. Our three picks cover those choices: the DEWALT DCD794D1 has a 5.88-inch tool head, the Bosch GSR18V-400B22 supplies two 2Ah batteries, and the Milwaukee 3404-22 adds a hammer mode in its M12 platform.
This is a comparison of manufacturer specifications, manuals and exact kit listings, not a hands-on performance test. The recommendations describe useful differences; they do not rank drilling speed, runtime or durability from testing.
Brushless drill kits at a glance
| Kit | Best reason to consider it | Battery and charger package | Main limitation |
|---|---|---|---|
| DEWALT DCD794D1 ATOMIC | Short 5.88-inch tool head; DEWALT 20V MAX system | One DCB203 2Ah battery and DCB107 charger | One supplied battery; drill/driver rather than hammer drill |
| Bosch GSR18V-400B22 | Two-battery kit with 20 clutch settings | Two BAT612 2Ah batteries, 18V charger and bag | No hammer mode; verify tool quantity because the itemized listings conflict |
| Milwaukee M12 FUEL 3404-22 | Hammer, drill and screwdriving modes in a 6-inch tool | One XC4.0 battery, one CP2.0 battery, M12 charger and bag | Manual limits masonry drilling to 3/8 inch |
DEWALT DCD794D1: our pick for a short tool head
The DCD794D1 is a brushless 1/2-inch drill/driver kit. DEWALT specifies a 5.88-inch tool-head length, a ratcheting chuck, an LED and a maximum no-load speed of 1,650 rpm. The short head is a useful reason to consider it when access matters, although the installed bit and battery also affect the space needed.
The manufacturer’s kit list includes the DCD794 drill, one DCB203 2Ah battery, a DCB107 charger and a belt hook. Choose this package if one supplied battery suits your work or you already have compatible DEWALT 20V MAX batteries. The 20V MAX label describes initial voltage without a workload; DEWALT states that nominal voltage is 18V.
- Pros: Short documented head length, 1/2-inch ratcheting chuck and a battery with charger included.
- Cons: No second battery in this kit and no hammer-drill specification. Choose the Milwaukee below if a documented hammer mode is part of your requirement.
Check for the DCD794D1 kit with its 2Ah battery and charger. The similar-looking DCD771C2 is a different model: DEWALT identifies its motor as brushed, so it is not a substitute for this brushless pick.

Bosch GSR18V-400B22: our pick for two supplied batteries
The Bosch uses a brushless motor, an all-metal 1/2-inch chuck and 20 clutch settings. Its 6.3-inch head is longer than DEWALT’s quoted 5.88-inch head; its two speed ranges are 0–500 and 0–1,900 rpm without load. These dimensions and speed ranges describe the tools, not a measured performance advantage.
Bosch lists two BAT612 2Ah batteries, an 18V charger, a belt clip and a carrying bag. A second supplied battery is the main reason to choose this kit over the one-battery DEWALT package if you are starting with neither system.
There is a tool-count discrepancy to check before buying: Bosch’s narrative describes a drill, but its itemized list puts “(2)” before the drill name. The Amazon component list is also ambiguous, while the product photo shows one drill and two batteries. Confirm the tool quantity with the seller; this recommendation does not promise two drills.
- Pros: Two documented 2Ah batteries, a bag and 20 clutch settings for screwdriving adjustment.
- Cons: The GSR18V-400 has no hammer mode. Its manual lists maximum drilling capacities of 3/8 inch in mild metal and 1-3/8 inches in wood; the 1/2-inch chuck size is not a universal hole-size rating.
Select the GSR18V-400B22 two-battery kit, and resolve the tool-count discrepancy before checkout. Do not inherit masonry specifications from the GSB18V-400: the shared Bosch manual separates that hammer-drill model from this GSR drill/driver.
Milwaukee M12 FUEL 3404-22: our pick when you need hammer mode
The 3404-22 kit contains the 3404-20 brushless hammer drill/driver. Milwaukee specifies a 6-inch tool length and an all-metal 1/2-inch chuck. Its selector provides hammer drilling, ordinary drilling and clutch-controlled screwdriving, making it the most versatile mode selection in this three-kit comparison.
The package includes an M12 XC4.0 battery, an M12 CP2.0 battery, the 48-59-2401 M12 charger and a contractor bag. These are M12 components; choose the kit as part of that system rather than assuming a battery from another platform will fit.
- Pros: Hammer mode plus two different-capacity batteries in a kit with a charger and bag.
- Cons: Hammer mode has a defined limit: the operator’s manual lists a maximum 3/8-inch masonry capacity for the 3404-20. It calls for carbide-tipped bits in masonry; do not treat this compact drill as suitable for every concrete-hole size.
Use the Milwaukee 3404-22 product page and Where to Buy route to find the exact kit. Check the kit number and both battery capacities; the 3404-20 number alone identifies the drill rather than this complete package.
How to choose between these kits
Start with batteries you already own, then check the manufacturer’s compatibility list for the exact tool and charger. DEWALT’s 20V MAX, Bosch’s 18V system and Milwaukee’s M12 system are separate buying decisions; voltage alone does not establish compatibility. The Bosch manual directs buyers to the included battery/charger list, and Milwaukee specifies M12 batteries and chargers for this drill.
Match the material, bit and hole diameter to the tool’s manual. Bosch explicitly marks masonry capacity as unavailable for the GSR18V-400, while Milwaukee gives the 3404-20 a 3/8-inch masonry limit. A brushless motor label by itself does not establish hammer capability or a drilling capacity.
Frequently asked questions
Are all three picks brushless?
Yes. Each manufacturer’s page identifies the selected drill as brushless. The older DEWALT DCD771C2 is brushed and is excluded from this shortlist.
Which kit includes two batteries?
Bosch’s GSR18V-400B22 lists two 2Ah batteries. Milwaukee’s 3404-22 includes a 4Ah XC pack and a 2Ah CP pack. DEWALT’s DCD794D1 includes one 2Ah battery.
Which of these can hammer drill?
The Milwaukee 3404-20 tool in the 3404-22 kit has a hammer mode. Follow its manual’s 3/8-inch masonry capacity and bit instructions. The Bosch GSR18V-400 is not the GSB hammer-drill model.
Is DEWALT 20V MAX directly comparable to an 18V label?
DEWALT states that 20V is the maximum initial voltage without a workload and 18V is nominal. That labeling detail does not establish equal performance or battery compatibility with another manufacturer’s drill.
Which one should I buy?
Choose the DEWALT for its short documented head and a one-battery start in that system, the Bosch for two supplied 2Ah batteries after resolving the listing’s tool-count discrepancy, or the Milwaukee for its documented hammer mode. These are fit-based recommendations, not test winners.
