Frequently Asked Questions

Can the FLEXVOLT handle concrete drilling?

No, the FLEXVOLT is designed for general-purpose drilling and fastening, not for heavy-duty masonry or concrete.

Are the batteries interchangeable between these models?

Both drills are part of DEWALT’s 20V MAX lineup, but the FLEXVOLT’s 2.0 Ah battery and ATOMIC’s 1.3 Ah batteries are not directly interchangeable due to different power profiles.

Which drill is better for prolonged use?

The FLEXVOLT, with its larger battery and higher power output, is better suited for extended, demanding tasks.

Is the ATOMIC suitable for professional work?

While capable for light professional use, the ATOMIC is primarily aimed at DIYers and light applications rather than heavy-duty jobs.

Find Your Perfect Match: Power or Portability?

Deciding between the FLEXVOLT and ATOMIC hinges on your specific needs. If you require a powerful, durable drill for demanding tasks, the FLEXVOLT is the clear choice. However, if you prioritize lightweight design and versatility for home or light projects, the ATOMIC offers excellent value and performance.
