Review: Excellent - Love it. I'm finally migrating from my first generation 20v brushed motor DeWalt impact. I expected it to be less powerful, and somewhat less intuitive. I was totally wrong. The torque multiplication is fantastic, just as good if not BETTER than my old unit (I can't say how it is relatively with the other brushless units, but it's probably a little bit lower performance. Three phase brushless systems are superior in every way you can slice it). It's very quiet, I mean probably less than half the decibels of my original. I set some of the iron works bolts that support my first floor to test; the tool itself makes so little noise it's amazing. The only thing that stood out, noise wise, was the actual impact cycles resonating with the steel beams. My 5 year old was sleeping directly above, and he didn't wake up for any of the eight large fasteners. The speed setting is awesome, but it's not just speed, the torque output is higher on speed two for sure, and I do not mean it makes more impact cycles per second (though it does), the actual torque is significantly higher. The speed setting should not be used as a drive restrictor, even though it probably could be with some practice (ballpark, thumb at arms length with one eye closed type of accuracy). I don't think the few mentions of non intuitive feel are fair or even accurate. Fire off one high friction screw into two pieces of pine, and consider your meatware calibrated. It weighs a lot.... A good deal more than my first gen unit. I'll put it this way, I put one of my 60v flex batteries on, and it was almost balanced just right. Price point is.... Eh. Could be better, but honestly, you get what you pay for. Hydraulic cavitation feels very nice, almost unnatural, but very very satisfying. Overall power is in range of expectations for the class for sure. I'm keeping my first gen for dum dum work, this unit is going to my workshop floor to use with electronics and other sensitive equipment. I frequently use a step down converter to use 5/32 bits with specialty types (no, I don't crank anything down with this, but I sure do break old fasteners free at full force!). The 20m work light is brilliant. Not that I don't already have an entire Division of purpose built lighting... This is just convenient when I don't want to drag another tool out for something quick or unforeseen. Battery consumption is very efficient due to the the phase solid state driven motors. I build these systems at the component level, I know them very well, you can't beat the efficiency and the power at such precision. This is a tank just like most of my DeWalt tools. I seriously doubt I'll be able to break it. You'd have to be a real a***hole to break one of these. I expect it to last indefinitely. I'm not 100% on how the hydraulic housing is configured, and if it will leak in 15 years or something, but I expect it was designed appropriately. Recommended, 10/10 ....and as a very picky engineer, I don't give anything full marks.
Review: A must have - This impact driver is amazing. So much quieter then all others and has light impacts if needed. I have now bought 2 of these I love it so much. I use them daily. They are very well built like all dewalt tools are and so worth the money. I can't really say if the battery lasts any longer with these versus a standard impact driver.

### ⭐⭐⭐⭐⭐ Can you hear me now?
*by D***X on October 22, 2025*

Quiet and powerful. For those that are Delwalt users, this is driver to get. To be fair, here at the end of 2025, the DCF860 is still the king of the driver's, but the DCF870 gets it done. I will take a little less power for the much lower volume when drivinf fasteners. I ran 2-1/2" #9 deck screws in and had to watch that i wasn't overdriving them. I stepped up to the 5-1/8" and its dropped them like a rock. The grip is comfortable as most Dewalts are today. No Hotspots with barehands. It feels solid but I haven't dropped it out of 2nd story window. The compact head will be great for working between studs. But the headline is how quiet it is. With predrilled holes i didnt even hear impacting until I got to the bigger fasteners. Granted this was all white pine. But when driving the aforementioned 5" mini lags, it was quieter than my 12V driving 2" #8's. When i put up plywood sheeting in my garage, everyone for half a block knew it using my old 887. If I'd have had the 870, no one would've had a clue. Its unquestionably by favorite impact these days. Now Dewalt how bout a fluid impact in a lower power form factor for furniture, trim work, and the like.
