Dewalt's QUIET New Impact Driver!

[@KjWilliams_]

Glad to see you back tinker. One of the most informative tool channels on youtube! The 870 has been my go to impact driver since it came out. So nice to use.

[@TinkerWithTools]

Thanks it felt good to be doing something normal and not moving stuff! Yeah I am enjoying the 870 so far! It has a nice blend of size and power while being really quiet for an impact.

[@KjWilliams_]

@ hopefully you’re almost done moving cause i know it’s no fun and I couldn’t agree more!

[@TinkerWithTools]

We are moved in, but now it's all the unpacking and set up/organization. Apparently making sure the kids have a place to sleep is more important than setting up my shop. 🤣

[@GregBrecker]

Thanks Tim. Good luck with the new place!

[@Adrian_Anderson]

We can't forget that Team Green also has an oil impulse driver. The Hikoki WHP18DA.

[@TinkerWithTools]

That one is easy to forget since it’s not in the North American market and the import tool only is going for about $340 right now. Makes the Makita seem reasonable.

[@engineer_alv]

Wouldn't using the exact same battery close the performance gap between these two? It looks like a 1.7PS on the DCF870 and the better performing 5 PS on the DCF860

[@TinkerWithTools]

@@engineer_alv there is a chance of it yes. Still getting settled in the new place and didn’t have access to more than a few batteries. Further testing will be done on like batteries.

[@nils1953]

I'm interested in the controllability of the impact. I've always found DeWalt to be lacking in terms of trigger control and impact control compared to Makita. Does this style of DeWalt impact remedy that gap? I'm just looking for an impact that I can control and not overdrive fasteners etc.

[@TinkerWithTools]

The control of the impact improves on a hydraulic in my opinion. I have enjoyed using this one so far and found it to be pretty precise. The trigger is still very Dewalt though. I don't think it's a bad trigger by any means but if you are looking for Makita levels I don't know that you will be fully satisfied here.

[@devonboyer626]

You also might just need a little more practice with the tool. I use an M18 Fuel impact, and on speed one that thing is great. You can literally feel when it's about to impact and stop it right before. Metabo HPT makes very controllable impacts (similar feel to Makita), and for a good price as well!

[@georgedavall9449]

Impulse/Hydraulic/Surge, w/e we want to call it, DOES add to the ability to control the tool, especially with smaller fasteners, in more delicate applications. It also is much smoother. As far as DeWalt goes, their triggers have always been some of the best, maybe not quite up to ‘Makita standards,’ but still good. The internal ‘wipers’ do get worn in the trigger area, and can lead to less trigger ‘feel,’ as well as loss of VS. Hope that helps?

[@nils1953]

@georgedavall9449 maybe, I ordered the Makita TD173D from Japan. Partially because the DeWalt hydraulic is even more expensive, and I do not like the trigger on my DCF850 (the speed mode selector has a mind of it's own so I can't rely on speed 1 for control). But also partially because I have an additional Makita battery laying around and I would have to buy another Dewalt battery. But I think if I need another driver after this one, I'd go with a hydraulic one, they look awesome to use with their tiny impacts on low speed.

[@allenriff9242]

Are you going to do a video on the new Makita XDT20?

[@TinkerWithTools]

@@allenriff9242 I have a video already on the Japanese version if you don’t want to wait but yes, when I get the new impact I will be doing a video.

[@markm0000]

Thanks for the video. My 850 gets loud with extended use. Just on the hearing loss alone I’m wanting to upgrade. I wish someday there’s a square anvil mod for this hydraulic impact.

[@TinkerWithTools]

TTC did a good video on the torque levels with it but given the standard applications with a square anvil I don't see it being as useful in that scenario but that would be cool.

[@TinkerWithTools]

Maybe I will have to sacrifice my old surge to see if it's even possible.

[@markm0000]

@@TinkerWithTools The reason why I like having a 3/8 anvil on my 850 as a mechanic is being able to use impact swivels, deep sockets, and special stuff like crows feet, turbo sockets for studs, large hex sockets, etc etc. It’s way easier than trying to get a ratchet into a cramped spot and having it slip and bust open my knuckles. The standard impact driver bits are very limited and I’ve snapped several of those hex to 3/8 adapters as you know.

[@markm0000]

@@TinkerWithTools why I like using the 850 so much is because of the weight. With a power stack battery it’s light as a feather and sometimes I’m working on something with my arm extended out and having a larger impact wrench like the 921 gets really heavy really fast and I don’t need to be busting 300 ft lbs on every little bolt.

[@MP99.]

much different sized batteries. Does that change anything when swapped?

[@TinkerWithTools]

I’ll be testing that more in future videos but both of these batteries are pretty performant.

[@calebcrockett1085]

I’ve said it since the first week I had my 870, it is the best impact for 90% of people! Carried a 850 for years at work and recently upgraded to the 860 but wish I had the 870 first.

[@TinkerWithTools]

I can get behind that statement.

[@SupremeAssemblies-x2j]

I dont get why they didnt add the LED buttons and light feature on the 870…

[@soundslight7754]

Thanks for sharing. In my opinion there isn't enough improvement to warrant a new purchase. I'm underwhelmed how small the difference is. I think the 860 still rocks! On the positive side, since I got a 1/4" hex shank chuck, the drill use has dropped significantly, most of jobs adequately handled with my impact driver which is a lot more civil so every little drop in noise level in the tool matters

[@TinkerWithTools]

As for improvement are your referring to the noise or were you expecting it to be superior to the 860?

[@soundslight7754]

@@TinkerWithTools Noise level

[@TinkerWithTools]

@@soundslight7754 it doesn’t really come across in the video unfortunately as the mics compensate a bit for the difference in volume. In person it’s pretty pronounced.

[@soundslight7754]

@@TinkerWithTools I can understand you, have to get hold of one of these to try out

[@calebcrockett1085]

The noise difference is substantial, love my 860 but for 90% of stuff the 870 gets the same thing done and is much easier on my ears. It’s enough of a difference the wife will tell me to go get the “fancy one” so that it’s quieter lol

[@taylorshin]

Boy.. finally!! Now my 850 don't have to work indoors!

[@TinkerWithTools]

It seems to be a solid impact so far.

[@TinkerWithTools]

Thanks George!

[@georgedavall9449]

@@TinkerWithTools My pleasure my friend! Hey, so what’s your thoughts on Ridgid’s heavier duty drills/ impacts? I know You didn't care much for the SubCompact line, and I searched for a review in your channel on the bigger models, but maybe missed it? I’m thinking of taking advantage of the Holiday deals, and getting into that battery platform, as I have a certain tool in mind, by Ridgid, for use ‘down the road.’ Thanks!!!

[@TinkerWithTools]

The sub compact I didn't like because of the slow ramp up that is present on those drills. As for the heavier duty drills, the high-torque hammer drill is a solid drill and their newest batteries (EXP batteries) are pretty nice. I have never been a huge fan of the Ridgid impacts but they aren't bad by any means. When you can get Ridgid on sale, I think that it's a good deal. When you are paying full price, my own personal preference would have me spend a little more to get a tool that I prefer more.

[@georgedavall9449]

@@TinkerWithTools I appreciate the reply and appreciate You Sir. I am inclined to agree with others that have posted about the ‘ramp up’ and how it might be for control? But I think your comment is very accurate, and I concur, and it is a help. I have heard their impact wrenches are solid. You proved the EXP batteries offer a ‘boost.’ Tools have a bright future with the newer battery technologies on the horizon. Thanks Tinker !!!!! 🤝

As long as he doesn't average over 85db in an 8 hour period OSHA says he doesn't need hearing protection. A few runs of some impact drivers for testing will cause ZERO damaging to his hearing.

Nice review!

[@TinkerWithTools]

Thanks!

[@peterc9166]

We had this conversation now we need the 12v refresh

[@TinkerWithTools]

I assume you are referring to the M12 surge? It's actually a few years newer than the M18 version. But I would take a refresh of both!

[@dreambuilt-l9294]

I definitely agree!!

[@snakesonn3590]

Been looking forward to see your video on this one!

[@TinkerWithTools]

it's a good impact. I'm excited for the next few videos on it!

[@snakesonn3590]

@ do you think it would be worth upgrading my 850 to this one?

[@TinkerWithTools]

They are different tools. A hydraulic impact will never match the raw torque of a traditional impact. But if all you are doing is driving smaller fasteners, then I do find myself liking a hydraulic impact more, especially indoors.

[@snakesonn3590]

@@TinkerWithTools thanks for the information

[@GoldMineArcade]

The 870 looks slow

[@TinkerWithTools]

If you are comparing it to one of the 2 or 3 fast driving impacts on the market yes it will be slower. I’ll have future videos against other competition.

[@philipeli1192]

Big waste of money for most,I have an 850 and 2 885,and a 845,I like the 845 the best.

[@TinkerWithTools]

It will depend on what you focus on or value you the most. The impacts you mentioned will certainly all accomplish the same jobs as this impact but then again, your 885 is the oldest model you mention and the 845 can't do much more than in can, it just does it faster and more efficiently.

Well I am tired currently but the talking portions of this video are filmed out in a cold, poorly lit garage. That will play into it.

[@gnshp8167]

I don't see a point in an oil/hydraulic impact at all. Its slower and has less power than a normal impact and for example an M12 drill will have more power, is more versatile and quieter anyway.

[@Vanman_fr]

The dcf870 is actually more powerful than some of the older dewalt impact drivers like the dcf887, dcf845, dcf809 and, dcf850. Ive been very impressed with it.

[@TinkerWithTools]

I think that it comes down to preference. Some people prefer to use an impact for most things and prefer the way that it operates versus a drill. This gives them a quieter impacting option. Additionally, the hydraulic impacts are smoother than a traditional impact so it improves on that as well. I full admit it's a luxury tool but I turn to it mor than a traditional impact for a lot of things at this point.

[@jetsetjoey]

*I'll gladly take the 30% increase in power of my DCF860 vs. the 10db reduction in noise of the DCF870...*

[@TinkerWithTools]

The reduction of 10db is not equal to a 10% reduction in noise. It's actually closer to half of the noise reduction. Sound doesn't progress in a linear fashion but instead on a logarithmic scale.

[@jetsetjoey]

@@TinkerWithTools, OK, then I’ll add that the difference that I could “here“ via my high-end, Altec Lansing speakers, conveyed by your video, was almost indiscernible. I’ll still take the 30% increase in power...
