The Verdict
If you need a lightweight, efficient drill for occasional tasks, the DEWALT ATOMIC offers excellent value. For those who want more versatility and the impact driver, the DEWALT combo kit provides a comprehensive solution.
Hands-On Impressions
In my hands-on testing, I appreciated how lightweight and balanced each drill felt. The atomic drill’s compact size made it easy to maneuver in tight corners, while the impact driver from the combo kit tackled tougher fasteners effortlessly. Both tools felt durable and well-made, with smooth operation thanks to their brushless motors. The LED lights on both were bright and helpful in confined spaces, making everyday tasks easier.
Performance in Real-World Use
During my testing, I used the atomic drill for hanging shelves and assembling furniture. Its 340 UWO was sufficient for most home projects, and the two-speed gearbox allowed for precision. The impact driver from the combo kit handled stubborn screws and bolts with ease, demonstrating its power and speed. Both tools maintained battery life well during standard use, though extended heavy-duty tasks drained them faster.
What struck me was how smoothly the brushless motors operated, offering less heat and noise compared to brushed counterparts. The impact driver’s quick-release hex chuck made bit changes swift, saving time on multi-step projects.
Build Quality & Reliability
DEWALT’s reputation for durability is evident in both products. The atomic drill’s compact body is made from tough materials that withstand daily use. The combo set’s tools felt sturdy, with well-designed grips and solid construction. The LEDs stayed bright, and the quick-change chucks remained secure after multiple uses. The warranty period reassures users about long-term reliability.
In my experience, these tools are built to last, provided they are used within their intended scope and maintained properly, especially keeping batteries charged and clean.
Running Costs & Battery Life
Both tools use 20V MAX batteries, which are common and easy to replace. The 2.0 Ah batteries provide a good balance of runtime and weight, but for heavy or prolonged work, extra batteries might be beneficial. Charging times are typical for DEWALT’s standard batteries, and the included chargers are reliable. Over time, battery capacity will decline, but the 3-year warranty covers replacements if needed.
In my testing, the impact driver set’s two batteries meant less downtime, especially during larger projects. The atomic drill’s single battery was sufficient for lighter tasks but would require recharging for extended use.
Who Should Choose Which?
If you mainly work on light to medium DIY projects or need a drill that fits into tight spaces, the DEWALT ATOMIC is an excellent choice. Its lightweight design and efficient brushless motor make it ideal for occasional use and smaller jobs.
On the other hand, if you want a versatile setup that includes both a drill and impact driver, suitable for more demanding tasks, the DEWALT combo kit offers greater flexibility. It’s better suited for professionals or serious DIYers tackling various materials and fasteners regularly.
Frequently Asked Questions

Which DEWALT Drill Fits Your Needs?
Both the DEWALT ATOMIC and the brushless combo kit have their strengths, making them excellent choices depending on your workload. If portability and ease of use are your priorities, the atomic drill provides reliable performance in a compact package. However, if you want a more versatile set with additional impact driving capabilities, the combo kit offers greater functionality for a broader range of tasks.
