Overview
The DEWALT DCF911B is a battery powered impact driver running on DEWALT's 20V system, weighing 2.6 pounds. The B suffix in DEWALT's model naming typically marks a bare tool, sold without a battery or charger included, so check the listing carefully if you need those in the box.
At 2.6 pounds, this sits toward the lighter end for a 20V impact driver, which matters for one handed overhead work or long sessions driving screws. Some spec fields attached to this listing, including amperage and speed figures, appear inconsistent for a battery powered tool and are not repeated here since they do not read as reliable.

Who it's for
Fits buyers already invested in DEWALT's 20V battery platform who want a light impact driver and are comfortable buying it as a bare tool. Not the right fit if you need a battery and charger included in the box.
Strengths and trade-offs
Drawn from this product's published specifications.
- Light 2.6 pound body for extended use
- Fits DEWALT's established 20V battery platform
- 4.7 rating across 2,926 reviews
- Sold as a bare tool, no battery or charger included
- Some listed spec figures for amperage and speed appear unreliable
Performance notes
A 2.6 pound body keeps fatigue down during repeated driving, especially in overhead or one handed positions. As a bare tool, its output depends on the 20V battery you pair it with rather than anything supplied in the box.
