Debated this one (845 XR) or the Atomic (850) - note: there are even newer ones coming
So, when the VERY short Dewalt Atomic 850 driver came out it got great reviews and really outpowered almost every other driver in the Dewalt ecosystem. I was sold, but then I started to read reviews mentioning reliability issues (from trades people in particular). Indeed, there were a LOT of them reporting they just didn't hold up. Around this same time, Dewalt released the 840 driver (Sheesh Dewalt....too many drivers!), and it had even more power, but was a little longer and had no speed controls. I assumed Dewalt would release a new XR version to replace their older (but still around) driver and sure enough - this 845 XR came along. Honestly, I'm pretty happy with it overall. Balance, power, control, etc. - all work really well for me. I just used it to install some shower grab bar anchor screws just the other day. No complaints for my uses cases which don't include driving a lot of big lags. The only downside to this tool and even the 850 was that it did not move the bar in terms of sheer power (important IF that is what you need) - especially as compared to Milwaukee and their monster drivers. If you do need that power, then maybe a Milwau....wait, this just in, Dewalt is releasing TWO MORE drivers this year. One is a hydraulic impact (nice for inside use!) and the other is clearly designed to go after Milwaukee on the power front. At first, I regretted not waiting for the new, more powerful, driver they ar releasing, but honestly, it is bulkier, likely heavier and, again for my use case, I'd rather have the smaller tool with likely more finesse (maybe not Makita level finesse, but still good). It is all about the RIGHT tool for the job (which is also why I have the more compact DCD800 drill driver as my every day drill over the BIG 99* series). Nothing wrong with the BIG BOY tools, but overkill for a lot of jobs. I am, of course, tempted by the new hydraulic driver...can't wait!

The Gold Standard for Cordless Driving Power
This DEWALT 20V MAX XR impact driver redefines expectations for compact tools. The brushless motor delivers 1825 in-lbs of torque in a package lighter than most competitors, while the 3-speed selector lets me match power to the task - from delicate cabinet work to driving 6" lag bolts. After six months of daily professional use, it shows no signs of wear and maintains consistent power through entire battery charges. **Key Features:** โ **Precision Control**: Electronic brake prevents over-driving โ **Compact Design**: Fits in tight spaces (5.3" head length) โ **Durable Construction**: Survived multiple 10ft drops โ **Efficient Brushless Motor**: 57% more runtime than brushed **Performance Highlights:** - Drove 500+ deck screws on single charge - Removed rusted trailer hitch bolts effortlessly - Maintained speed under load **Technical Advantages:** โ 0-3,400 RPM / 0-3,800 IPM โ Belt hook included โ LED worklight with 20-second delay **Why Professionals Choose It:** - Actually fits between 16" on-center studs - Provides noticeable vibration reduction - Delivers consistent power until cutoff **Perfect For:** โข Framing crews needing all-day tool โข Electricians running conduit โข Automotive technicians While tool-only, it's worth investing in DEWALT's 20V system. The balance and power make this my go-to for any driving task, eclipsing heavier models I've used for years. **Why 5 Stars?** - Exceeds pro-grade expectations - Innovative speed control prevents material damage - Built to withstand jobsite abuse A rare tool that makes you work faster with less fatigue. The DCF845B has become my most reached-for driver, proving that smart engineering beats raw power alone. **Note:** Pair with 5Ah battery for heaviest tasks. **Pro Tip:** Use speed 1 for precision work, speed 3 for stubborn fasteners. This impact driver represents the perfect balance of power, control, and durability - worth every penny for serious users. It's ruined me for lesser tools. **Bonus:** The tri-LED light actually illuminates the work area effectively.

Two Years of Hard Use and Still Feels Like New
I've been using this impact driver as my main tool for all my home improvement projects for the last two years, and it has been absolutely rock-solid. This has been my workhorse for everything from big jobs, like framing new walls, to countless smaller tasks around the house. It has handled every screw I've needed to drive with plenty of power and control. The brushless motor is efficient and has never once struggled. The most impressive part is its durability. After two years of consistent use, it honestly still feels and performs like it's brand new. It's a testament to the quality of the DEWALT XR line. If you're looking for a reliable, powerful impact driver that will last, this is it.
