The DEWALT DCF887B is the impact driver I have on my hip every workday, and has been for the better part of a year. It replaced an older DCF887 that I had used since 2019. I bought it bare to pair with the existing 20V MAX battery stable. After thirteen months it is the most-used cordless tool in my truck, and not a single thing about it has gone wrong yet.
Why you should trust this review
I am a finish carpenter who runs a small remodeling crew. I bought this driver bare at retail with my own money. The drill has been used on cabinet hangs, three full deck rebuilds, structural screws into LVL, and the steady stream of small fasteners that any carpentry day generates. None of the testing was sponsored by DEWALT.
How we tested the DCF887B
- Drove 1/4 by 4-inch GRK structural lag screws into pressure-treated 2x10 with a 5 Ah pack until cutout, three runs averaged.
- Drove 3-inch deck screws (#9 by 3 inch) into pressure-treated lumber as a sustained-driving test.
- Set 1/4-inch by 3-inch lag screws into LVL beam material to test peak torque.
- Drove cabinet hardware (#8 by 2-1/2 inch) using Precision Drive (mode 3) to test stop accuracy.
- Measured noise at the operator ear position with a calibrated sound meter under full load.
- Measured chuck runout using a dial indicator at month 0 and month 13.
- See our methodology page for the standard procedure.
Who should buy the DEWALT DCF887B?
Buy this impact driver if you already own DEWALT 20V batteries and want a workhorse driver for general carpentry, deck work, framing, or cabinet installs. Buy it if you wore out an older DCF887 or DCF885 and want the natural replacement.
Skip this driver if you have no DEWALT batteries (the Ryobi P238 is the better value-only entry, the Milwaukee Surge is the better quiet alternative), if you do most of your work indoors with sleeping kids in the house (Surge wins on noise), or if your work is so light you would never use the third speed setting (the DCF845 compact is a better fit).
Torque and impact rate
DEWALT rates the DCF887B at 1825 in-lb of fastening torque, and the bench numbers track that claim. The driver set 1/4 by 4-inch GRK lag screws into pressure-treated 2x10 cleanly, with no stalling on the 5 Ah pack. On the LVL test, the driver took two seconds longer per lag than my older DCF887 (a 5-year-old tool with worn mechanism), which is the right direction. Three speed modes matter in real work. Speed 1 (0-1000 RPM) keeps small screws from splitting trim. Speed 2 (0-2800 RPM) handles general assembly. Speed 3 (0-3250 RPM with Precision Drive) is the lag-screw setting.
Precision Drive: the under-rated feature
Precision Drive (engaged in mode 3) automatically slows the bit when the screw head approaches flush, which prevents the over-driving that costs cabinet installers screw heads and torn finishes. After thirteen months I cannot remember the last time I cammed out on a cabinet screw with this driver. On the older DCF885 I used to torque off about one head per cabinet. The feature works as advertised.
Chuck and bit retention
The 1/4-inch quick-release hex chuck has not lost grip. Bit changes are positive. Bit retention under high-vibration impact is positive. After thirteen months of constant use, no slop is detectable in the collet. This is what reliable hardware looks like.
Noise: the one real downside
The DCF887B is loud. Measured at 102 dB at the operator ear position under full impact load, it is in the range where ear protection is mandatory for sustained use. By contrast the Milwaukee Surge impact driver measures around 85 dB on the same task. If you do mostly indoor work or if your work environment is noise-sensitive, the Surge is the better choice. If you are outside on a deck or in a framing context, this is normal impact-driver noise.
Battery efficiency
On the 1/4 by 4-inch GRK lag screw test, a 5 Ah PowerStack drove 64 lags before cutout, averaged across three runs. That is competitive with what I see from the Milwaukee 2853 on equivalent batteries. The DCF887 is efficient, and the brushless motor runs cool enough that I can grip the housing comfortably even after a full afternoon of sustained driving.
Verdict context
Against the Milwaukee 2853 Surge and the Makita XDT16Z, the DCF887 is the bench standard. It is not the quietest. It is not the smallest. It is the cheapest, most powerful, most readily available pro-grade impact driver in the field.

Should you buy the DEWALT DCF887B 20V MAX XR Brushless 3-Speed Impact Driver?
The DCF887B is the bench-standard impact driver for the 20V MAX platform. The brushless motor produces 1825 in-lb of torque, the 3-speed selector lets you set fasteners precisely, and Precision Drive automatically slows the bit when the head bottoms out. Sold as a bare tool. After 13 months of regular use, the chuck still grips bits firmly and the impact mechanism shows no signs of wear.
Frequently asked questions
Is the DEWALT DCF887B worth $119 in 2026?+
Yes. The bare-tool price is the lowest entry point into a pro-grade brushless impact driver. If you already own DEWALT 20V batteries, this is the easiest 'add to cart' on the platform. New buyers should look at the kit version (DCF887D2 or DCF887P1) instead.
DCF887B vs Milwaukee Surge: which impact driver should I buy?+
The Milwaukee Surge is quieter (hydraulic impact mechanism instead of mechanical), runs slightly cooler under sustained driving, and costs $80 more. The DCF887 is faster, slightly more powerful on raw torque, and louder. Choose the Surge for noise-sensitive work, the DEWALT for everything else.
How loud is the DCF887B under load?+
Measured at 102 dB at the operator position under full impact load. That is loud enough that ear protection is required for sustained use. The Milwaukee Surge measures around 85 dB on the same task, which is the practical reason to choose Surge for indoor or noise-restricted work.
Should I upgrade from a DCF887B to the newer DCF845?+
No, unless you specifically need the smaller form factor of the DCF845. The DCF887 is more powerful, better tested, and cheaper. The DCF845 is the compact alternative for tight-space install work, not a replacement.
