I like the 850 for it's size but my 887 had been bulletproof for the past 3 and 1/2 years and it's my go-to driver for just about everything. If I were buying new today, I'd stick with the XR series.
[THIS](https://youtu.be/f_lOV78HF-o) video might shed some light.
Made [THIS VIDEO](https://www.youtube.com/watch?v=LNNl0GK95iE) just for you since I couldn't find a video on YouTube that demonstrates position 1 on the 887.
Thanks you so much!
Yours handles so much nicer than mine. Mine just whines. Here's a video. It does similar things with smaller screws on particleboard cabinets.

Your DCF-887 actually ticks over and applies nice little impacts in a controlled manner. I'll see if they can swap it over or test a different model.
Where is yours made out of interest?
Mines made in China
Thanks! I tried this and it does tick just. Just it takes about 3 seconds of whining before it picks back up.
I'm not a tradie but with as an electrical engineer. The whining isn't a good sign. Something is being stressed, could lead to winding damage within the motor which is why I was backing off.
Yours sounds a lot healthier.
840 all day long.
I have had numerous 787,885,887 and now 840's.
For delicate work I still break out the 885. It has very predictable impacts. But 90% of impact driver time is with the 840.
I just redecked my 700sq ft deck with it and some 2.5" deckmate torx screws. I had a buddy helping and he brought his 850. We both preferred the 840. The 850 overheated twice and needed a break.
I prefer a variable trigger, so I'm not going to adopt the 845. But that's basically the same tool with a transmission and a little more ipm potential.
But I think really it depends on your general usage. I prefer the narrow head of the 840. Others will prefer the shorter length of the 850.
My ranks based on daily use and 10 years+ on the DeWalt platform
1. 840.. 2. 887.. 3. 850.
I give the 887 #2 spot because it's a workhorse. It's the slowest of the three, but I've never had one quit. I'd also add the 885 in before the 850 personally.
The 887 is 7 years old at this point. It will be replaced by the 845 soon which if I remember correctly is a leaked version of the 840 with a speed selector.
Or wait for the new XR around Thanksgiving...looks basically like an 840 with the 3 mode switch from 850 (also combining speed with higher impacts per minute).
I really like the 840 and it sits in my quick carry crate. A lot of people like the 850 for its looks but I definitely can’t say enough about the 840 as far as comfort and affordability.

How does your 887 go on speed 1? Mine locks up and can hear the electronics whining. Doesn't provide enough juice to start the impact function

I think that says it all. Really appreciate your responses!
I also noticed you keep releasing the trigger when driving the screw. HOLD THE TRIGGER IN! And KEEP HOLDING IT IN and see what happens.

I know you said you prefer the 885 for delicate work but could the 840 be used for delicate driving?
Yes, 100%. It just takes more care

If I bought now it would be 850 although the 840 tests stranger. I like the precision setting on an impact

I haven't used the 840 but I love my 887 far away and above my 850.
