DeWalt DCF850 vs DCF887: New Compact Impact Driver Faces Its Predecessor

Introduction

DeWalt’s newest impact driver, the DCF850, arrives with a bold claim from the company: it is their most compact, highest torque, highest speed impact driver ever. That is a strong statement when the tool it replaces is the DCF887, a long-serving favorite that many users still rely on daily.

To see whether the new model justifies the hype, both drivers were put through a series of side-by-side fastening tests using fully charged 5 amp hour XR batteries on each tool. The comparison covered light-duty wood screws, aggressive structural fasteners, and self-feeding bits driven through two by fours, along with a look at the LED work lights and collet quality.

Speed 1: Three Inch Wood Screws

The first test used three inch wood fasteners on speed 1, the setting generally agreed to be for more delicate work. The DCF887 struggled to fully seat the screw, leaving a small amount of the fastener proud of the surface. The DCF850 drove it completely flush.

What stood out was how the DCF850 handled the final part of the drive. It met resistance, paused, and then applied just enough power to set the fastener. The older DCF887 already had a precision drive style that prevented overdriving, and the DCF850 appears to have upgraded that technology further. As a speed 1 test this was not the harshest challenge, but the newer tool clearly got the job done.

Speed 2 and Speed 3: Where Most Work Happens

Speed 2 is where many experienced users spend most of their time on the job, so it is a meaningful setting to compare. In the speed 2 round the DCF850 showed noticeably more drivethrough tendency, pushing the fastener deeper into the finished material. The same pattern repeated on speed 3, where the result was close to a photo finish but the DCF850 again seated the fastener deeper.

That extra aggression cuts both ways. It means more capability in demanding material, but it also means less forgiveness on finished surfaces. Users moving from the DCF887 to the DCF850 should expect a short adjustment period on speed 2 and speed 3.

LED Work Lights and Collet Quality

The LED work lights on both tools are bright, but there is a clear difference in character. The DCF850 uses clear lenses, while the DCF887’s lenses have a yellow tint visible around the corners of the beam. The clearer light on the new model was noticeable even while simply switching gears, and it is an easy preference to justify.

Quarter Inch by Six Inch Structural Fasteners

The tougher stage of the comparison used quarter inch by six inch structural fasteners, run on speed 3 with both batteries confirmed fully charged. Both drivers completed the drives, with the DCF850 again showing a bit more depth at the end of each fastening. For heavy framing and structural work, neither tool left any doubt about getting the fastener home.

Self-Feeding Bits Through Two by Fours

The final test was the most aggressive: one inch self-feeding bits chucked into each driver and driven straight through two by four lumber. Both tools powered through the boards impressively, with no hesitation or stalling from either model.

This is the kind of test that exposes a weak motor or an underbuilt transmission, and neither the new compact flagship nor the made in the USA with global materials predecessor showed any weakness here.

Which One Should You Buy?

The DCF887 remains a proven, comfortable tool that many users prefer for its predictability, especially on speed 2 where it is less likely to blow through finished material. It is the sensible choice if you value consistency and already know its behavior well.

The DCF850 makes sense for anyone who wants the most compact package with the highest claimed torque and speed in the lineup, upgraded precision-drive behavior, and brighter clear-lens LEDs. Be prepared for its extra drivethrough on the higher speeds.

Conclusion

The DCF850 lives up to its billing as DeWalt’s most compact, highest torque, highest speed impact driver, and it edged the DCF887 in nearly every head-to-head drive. The older model is still excellent, but the new tool’s refinements in precision, lighting, and power delivery make it a genuine step forward rather than just a refresh.
