DEWALT ATOMIC Drill vs DEWALT Brushless Drill: Full Breakdown
DEWALT 20V MAX Cordless Drill Driver Set

The DEWALT ATOMIC is a compact, lightweight drill designed for precision and ease of use in confined areas. Its brushless motor offers longer run time and durability, making it a solid choice for those who need a reliable, portable drill for frequent use. Its 2-speed transmission and LED light enhance usability for both drilling and fastening tasks.
Pros:
- Lightweight and compact at 7.6 inches
- Brushless motor for efficiency
- Includes 2.0 Ah battery and charger
- Ergonomic grip for comfort
Cons:
- Limited to 340 UWO power, not for heavy-duty tasks
- Single-sleeve ratcheting chuck may be less versatile
- Battery life could be longer for prolonged use
Best for: DIYers and professionals working in tight spots with moderate drilling needs.
Not ideal for: Heavy-duty construction or constant, high-torque applications.
Bottom line: Great for lightweight tasks and tight spaces, with longer battery life thanks to its brushless motor.
DEWALT 20V MAX Cordless Drill and Impact Driver

The DEWALT 20V MAX Cordless Drill and Impact Driver set offers more versatility, especially with the inclusion of an impact driver alongside the drill. Its brushless motor provides durability and efficiency, making it suitable for both light and more demanding tasks. The compact design and ergonomic grip make it comfortable for extended use, while the quick-release hex chuck allows for fast bit changes.
Pros:
- Includes two tools and two batteries
- Brushless motors for efficiency and longevity
- Quick-release hex chuck for ease of bit changes
- Compact and lightweight at 7.6 inches
Cons:
- Slightly bulkier when both tools are stored
- Impact driver adds weight and complexity if not needed
- Higher overall cost due to two tools
Best for: Homeowners and professionals needing both drilling and impact driving capabilities in one kit.
Not ideal for: Purely lightweight tasks or minimal tool sets.
Bottom line: A versatile, two-tool combo kit ideal for diverse projects, offering great value with two batteries.
| Feature | DEWALT ATOMIC Drill | DEWALT Brushless Drill |
|---|---|---|
| Size & Design | Compact at 7.6 inches, lightweight for tight spaces | Same compact size, suitable for versatile tasks |
| Motor Technology | Brushless motor for longer run time | Brushless motor for durability and efficiency |
| Power Output | 340 UWO, ideal for moderate tasks | Comparable power with 2,000 RPM and impact rate |
| Included Accessories | 2.0 Ah battery, charger | Two batteries, charger, and bag |
| Weight | 2.0 lbs | Approximately 3.0 lbs with two tools |
| Control Features | LED light, 2-speed | LED light, variable speed, quick release chuck |

The Verdict
Both drills excel in compactness and efficiency, but the Atomic is perfect for those prioritizing lightweight, single-tool use, while the combo kit appeals to users needing versatility and impact capability.
Hands-On Impressions
In my testing, I found the Atomic drill to be incredibly easy to handle for one-handed use, especially in tight corners. Its lightweight design meant fatigue was minimal during extended tasks. The brushless motor delivered consistent power, and the LED light was helpful. The two-tool set with impact driver felt more robust, but slightly heavier, which mattered during prolonged use. Both felt durable and reliable, but I appreciated the Atomic’s simplicity for quick jobs.
Performance in Real-World Use
In practical scenarios, the DEWALT ATOMIC proved excellent for light to medium tasks like drilling into wood, plastic, and light metal. Its 2-speed transmission allowed for precise control, and the LED light illuminated dark spaces effectively. However, for tougher applications requiring high torque, the Atomic’s 340 UWO was adequate but not overwhelming. On the other hand, the DEWALT brushless drill and impact driver combo handled a broader range of materials, including tougher woods and fasteners, with ease. The impact driver’s high impact rate made driving large fasteners much faster, and the brushless motors maintained consistent power without overheating.
Build Quality & Reliability
Both tools felt solid and well-constructed during my testing. The Atomic’s lightweight design does not compromise durability—its body feels sturdy, and the brushless motor seems built to last. The combo kit, with two tools, had a slightly more robust feel, especially the impact driver, which is designed to withstand frequent use in demanding environments. The ergonomic grips on both models are comfortable, reducing fatigue, and the LED lights are bright enough for confined spaces. Overall, both are reliable DEWALT products that should serve well over time with proper care.
Running Costs & Battery Life
Battery life is an important consideration. The Atomic’s 2.0 Ah battery provides decent runtime for typical DIY jobs, but may need charging during prolonged use. The two-battery set in the combo kit offers more flexibility, allowing one to charge while using the other, which is advantageous for larger projects. The brushless motors are more efficient, translating into longer run times per charge. Cost-wise, the Atomic set is less expensive, but the two-tool kit offers greater versatility and potentially longer overall use before needing replacements, especially with two batteries included.
Who Should Buy Which?
If you primarily need a lightweight, compact drill for occasional use, especially in tight spots, the DEWALT ATOMIC is a perfect choice. Its simplicity, efficiency, and affordability make it ideal for DIYers and professionals who value portability. Conversely, the DEWALT brushless drill and impact driver combo set is better suited for users needing a versatile toolkit capable of handling a wider variety of tasks, including driving larger fasteners and working on diverse materials. The impact driver’s added power and the inclusion of two batteries make it a more comprehensive solution for demanding projects.
