In my testing, the FLEXVOLT felt robust and handled tough drilling with ease, especially in dense materials. The ATOMIC was surprisingly capable for its size, making quick work of screw-driving and light drilling without fatigue. Both drills were easy to set up and felt comfortable in hand, but I appreciated the extra power of the FLEXVOLT for more challenging projects.
