Overview
The DEWALT DCF923 is a 20V Max cordless impact tool weighing 2.76 pounds bare, sized for one-handed use on fasteners. The listing carries a 5 amp rating alongside its weight, on DeWalt's common 20V Max battery platform.
The spec sheet also lists a speed figure that reads as 2.5 RPM, which is almost certainly a data entry issue since no impact tool runs that slow, so that number is left out here rather than repeated. What is solid is the 20V Max platform and the sub-3-pound bare weight, both consistent with a compact impact driver built for overhead and tight-space work.
- 20V Max battery powered
- 5 amp rating listed
- 2.76 pounds bare weight
- Part of DeWalt's 20V Max tool line
Who it's for
Suits DIYers and tradespeople already invested in DeWalt's 20V Max battery line who want a light impact tool for driving fasteners. Less useful for anyone needing a corded tool or a different battery platform.
Pros and cons
- Light at 2.76 pounds bare for one-handed use
- Runs on DeWalt's common 20V Max battery platform
- Listed speed figure appears to be a data error and can't be relied on
- No description or review text provided to confirm real-world torque or runtime
Performance notes
Weighing under 3 pounds bare, the DCF923 is light enough for overhead fastening without the fatigue of a full-size impact wrench. It draws from DeWalt's 20V Max battery line, so runtime and torque depend on which battery pack is paired with it, information not included in this spec sheet.
