The Verdict
If you need a lightweight, budget-friendly drill for occasional use, the Atomic is suitable. For more demanding tasks and versatility, the Brushless kit is the better choice.
Hands-On Impressions
In my testing, the Atomic drill handled light fastening and drilling in tight spots effortlessly, thanks to its compact size and lightweight feel. When I moved to more demanding tasks, like drilling into hardwood or longer fastening sessions, it began to show its limits. The Brushless kit, on the other hand, felt more robust, with noticeably more torque and a more comfortable grip during extended use. The extra batteries and impact driver in the kit made it versatile for various projects.
Performance and Power in Real-World Use
The Atomic drill performs admirably in light to medium tasks, such as assembling furniture, drilling into drywall, or fastening screws in tight spaces. Its 340 UWO torque is sufficient for most household projects, but it struggles when faced with tougher materials like dense hardwood or large lag bolts. The brushless motor provides efficiency, but the overall power limits its heavy-duty capabilities.In contrast, the full kit with the brushless motor offers higher torque, making it more suitable for demanding applications like framing, deck building, or extensive fastening work. The variable speed trigger and quick-change hex chuck make it easier to control and switch bits quickly, which is a noticeable advantage in professional settings or intensive DIY projects.
Overall, the decision hinges on the scope of your work: light tasks favor the Atomic, while larger jobs benefit from the power and versatility of the Brushless kit.

Both drills share a similar compact size and ergonomic design, with comfortable grips and well-balanced weight distribution. The Atomic’s lightweight build (around 3.4 lbs) makes it easy to maneuver for extended periods, ideal for overhead or prolonged tasks. Its solid construction ensures durability for light to medium use.The Brushless kit, being slightly heavier (around 4.5 lbs), offers a more substantial feel that can be advantageous for heavier drilling. Both tools are backed by DEWALT’s 3-year limited warranty, reflecting its confidence in their reliability. During testing, both units performed without issues after several weeks of regular use, and the LED lights proved helpful in dimly lit environments.

Its single battery and charger keep initial costs lower, but you’ll need to consider purchasing additional batteries if you plan extended use.The Brushless combo kit, while more expensive upfront, offers better value for those requiring a versatile, durable tool that can handle frequent or heavy-duty use. The two batteries included provide extended runtime, reducing downtime, and the impact driver adds extra functionality.
In terms of running costs, both tools use standard DEWALT batteries, which are durable and widely available. Battery replacements or upgrades can be factored into long-term expenses.
