Positive

With a 1.7Ah PowerStack battery it gives a perfect balance of weight, power and size, and is a must-have in their kit.

Reddit · r/Dewalt · Jan 14, 2026 · summarized

Positive

Converted to a 3/8 wrench and used four or five times a week for years on a small power-stack battery; heavily abused and still performing.

Reddit · r/Dewalt · Jan 9, 2026 · summarized

Positive

Initially unsure about the precision first mode, but after a few uses finds it a handy built-in screwdriver-like feature that saves reaching for a drill.

Reddit · r/Dewalt · Jul 14, 2025 · summarized

Positive

Stunning for its size, a bit noisy, drives big structural lags easily; planning to keep it until it dies.

Reddit · r/Dewalt · Jul 13, 2025 · summarized

Positive

Full power and speed jobs and tight quarters go to it, alongside a small quiet M12 hydraulic driver.

Reddit · r/Dewalt · May 27, 2025 · summarized

Mixed

Strong power, but needs a 3Ah or larger pack; on a new 1.5Ah battery the performance was a letdown. Also owns an older stubby driver preferred for carpentry.

Reddit · r/Dewalt · Feb 17, 2025 · summarized

Mixed

Really liked, but fat and hard to reach into tight spots, so a slimmer sibling model gets used alongside it.

Reddit · r/Dewalt · Feb 17, 2025 · summarized

Positive

Handled every fastener tried across two years of deck building and house remodels, with no problems.

Reddit · r/Dewalt · Sep 28, 2024 · summarized

Positive

After an anvil swap done about six months ago they use it almost daily on a truck and find the added play not a problem.

Reddit · r/Dewalt · Aug 24, 2023 · summarized

Positive

Laborer using it a few times a day finds the size perfect and has already beaten it up hard.

Reddit · r/Dewalt · Aug 19, 2023 · summarized

Positive

A Home Depot bare-tool deal with a free battery brought it home, and it is loved.

Reddit · r/Dewalt · Aug 19, 2023 · summarized

Positive

A $59 clearance find after a previous impact driver died, and it is loved.

Reddit · r/Dewalt · Aug 18, 2023 · summarized

Mixed

New owner finds the lowest mode too weak, the middle mode slightly over the top, and the top mode crazy powerful; also likes its slim, quiet body.

Reddit · r/Dewalt · Aug 18, 2023 · summarized

Positive

Amazingly powerful for its size and runs all day on a 6Ah FlexVolt battery, though even larger packs get off balance.

Reddit · r/Dewalt · Aug 18, 2023 · summarized

Positive

Loved and among the most used tools in their kit; they skip socket adapters and reach for a dedicated impact wrench for that.

Reddit · r/Dewalt · Aug 18, 2023 · summarized

Positive

Daily full-time carpentry since release and it still works great.

Reddit · r/Tools · Apr 25, 2023 · summarized

Positive

Modified with a 3/8 anvil for tight automotive work; a larger wrench has more power, but this stubby one wins on how little space it needs.

Reddit · r/Dewalt · Apr 18, 2023 · summarized

Positive

Converted with a 3/8 anvil, its shorter body removes bolts inside motorcycle forks where a longer wrench gets stuck.

Reddit · r/Dewalt · Mar 15, 2023 · summarized

Positive

The stronger of their two impact drivers, next to an older one still going strong after nearly eight years.

Reddit · r/Dewalt · Oct 29, 2021 · summarized

Positive

First speed has good logic, backing off when it senses a speed drop; trusted more than the older 3-speed on small fasteners.

Reddit · r/Dewalt · Oct 11, 2021 · summarized

Positive

Owned since launch and loved, with an older brushed model kept too; it fixes what they disliked about earlier brushless DeWalt impacts.
