## What reviewers say

One whitelisted tester, Pro Tool Reviews, published a hands-on, measured review of this exact DCD999 model, scoring it 9.5/10. It praised top-tier performance that surges with a FlexVolt battery on high-demand drilling, while flagging that peak output requires running a heavy battery. All quotes and measured hole-saw drill times and weights were verified against the source. (Based on 1 review, 1 lab-tested, 2023-05-23.)

Praised: Top-tier performance that crushes competition when paired with a FlexVolt battery; Large measured speed gains on high-demand drilling (84% faster with FlexVolt on the 2 1/8-inch hole saw); Brushless motor, three speeds, and LED light controls relocated to the foot.
Flagged: Requires a heavy FlexVolt battery to unlock the best performance, adding weight.
Disagreement: Single-source only, so no cross-source disagreement could be assessed. Pro Tool Reviews itself notes the weight-versus-performance tradeoff but judges it to work in DeWalt's favor.
