*Awesome impact **MyBest.Tools** Takes tires off in a second. Plenty of power for what I’ve used it for - rotating tires. Using it on 3rd setting for removal and 2nd setting for tightening lugs.*
Forget the haters - it's true this didn't really prove anything but these goofy things are fun to watch :-) I'm looking to get one of these 899's because I want to learn some more car maintenance so I'm going to tackle a bad water pump replacement on an old honda. Apparently those crank pulley bolts might come right off with a special tool and a couple breaker bars, or if you're unlucky you might spend 3 days throwing everything at it. I don't have a garage to work in so I can't afford to get stuck once I get started - hence looking to have the big guns ready from the start. Thanks for the demo.
Thx man I appreciate that 👍. And for your crank shaft I would try the impact first you might be surprised... and if that doesn’t work out then get the special socket that is just super heavy and increase the torque of the impact that combined with the 899 and you will be fine for any project 🤙
the problem with ur test is ur literally clamping down on the bolt itself its kinda of skewing things, ill tell u from personal experience with both since both guns have been out, the 899 is n absolute beast itll snap bolts all day long, also the numbers arent technically speed settings, yes they affect that but the numbers refer to what torque level u want, 1 being snap any bolt, 3 being turn the world when u hit the trigger
after buying the 889w/5ah. bat. then before it was delivered I was offered I the 899w/4ah bat.,charger, an bag for $20 more so i bought it thinking to send one back . long story short thanks to your video i think i,ll keep them both
A salesman, Why don't you RUclips creator go to a auto salvage yards and start testing these impacts on rusty bolts instead of these new bolts, action speaks more than 20 minutes of words.
I’m pretty limited on the size of bolt I can find in Canada ☹️. I just purchased a worx pegasus workbench but my first choice would have been the keter but unfortunately it is impossible to find in Canada 😩
Yeah he forgot to try the older one again because it was turning but had a new set up for the new items didn't turn it again with the older model the old one would do the job too 😉 lol he was all about the new one from the Start of the video if you asks me
Shane Clews I don't know I was hammering in it for a while before it started tuning in the vice. I think compared to the Milwaukee HD 18 that extra 50 ft-Ibs may be the key.
I tried to actively search for Dewalt 899 on yt, only found a few, the same for days, suddenly something happened and now there are huge amounts of dewalt 899 videos here on yt. Is this some kind of block against dewalt, throttling down their brand.
If you wanted to measure the bolt sheer strength, that would be one way to do it. But you can't directly use a torque wrench to measure an impacts torque.
"I hope they're going to stabilize battery platform"... are you kidding right now? The 20v Max line came out in 2011... "keep changing". Except they did the 18v and then the 20v... that's the only relevant change for the video you're referencing. Both batteries are 100% interchangeable for the impacts you're using.
@@jasonmorehouse3756 There is some confusion over the battery formats here.

I used ruclips.net/user/postUgkx4ynqaujg7rZKFapA8s29kTpRszJGa3-K this for the first time today to replace the front wheel bearing on my rwd 98 dodge dakota. This had absolutely no issue removing or reinstalling the lug nuts and it took off the axle nut without any struggle. Sounds like it's got some muscle to it. Time will tell
Weakened bolt woth one then finished eith other. Say its m10 but thay doesnt matter as much as the grade of the bolt which measures tensile strength. Dont hate on videos very often and OP seems like nice guy, besides putting puppies in vices, but should think through tests before filming
“Chuck”? impact wrenches have a drive “Anvils” not chucks, hammer drill drivers have chucks, lol Yeah I know, the guy said it chuck, he meant socket I guess.
177bandit Sometimes you have to break it otherwise you need to use a torch or a cutting tool to remove the rusted bolt so in my opinion it’s a lot safer to break it then using a torch and heating up the metal.
patdud1979 sometimes you spend more time drilling when you break bolts. it takes 3 mins to heat to up bolts to remove. if you know how to properly use a torch, there is no need to break any bolts!!
The 20 volt drill is an 18 volt it's just sold in America as 20 volt because the battery can produce 20 volts and the flexvolt battery can be used in anything 18-volt up to 50-volt I think it's just because Americans think bigger is better you're actually getting the same thing branded in a different way
I see 3 flaws in your test. As mentioned earlier, use the same amp battery on both impacts. Place a higher amp battery in your car and see how much stronger your starter becomes. Use a different bolt everytime, each time you torque a bolt it stretches and weakens. Last but not least each test should be timed. That's the deciding factor if all else is equal. Good luck.
That's only because of lower resistance with the bigger lead acid battery that keeps voltage closer to what is printed on the battery. You can use high discharge lithium batteries that are low amp hour rating btw, but still achieve the same thing...Done all the time in R/C cars where you want lightweight, but super high discharge capability. So not entirely accurate of what you say that bigger is better.
Why don't video makers edit out their cock ups? Fitting a 17mm instead of a 19 for a 12mm bolt makes the operative look comical. Easy mistake just edit it out.
The entire premise of your 'test' is fatally flawed, because you didn't set up (or bother to mention) the critical ENVIRONMENTAL CONTROLS that are in place to develop a clear and factual conclusion. You are comparing two different impact wrenches made by the same manufacturer, that have a 75% difference in performance. (400 ft/lbs. vs. 700 ft/lbs.) That is frankly...ridiculous. So what's the point of this video? That one impact wrench is more powerful than the other? Common sense would tell you the 899 would win the 'test' easily. Did you do any homework PRIOR to running this head-to-head comparison? I mean really simple things like...WHAT IS THE MANUFACTURER RATED SHEAR STRENGTH OF THE FRIGGIN BOLT YOU BOUGHT IN THE FIRST PLACE? 60,000 psi bolt tension? 70,000? 80,000? Videos like this can in some cases be both educational and entertaining at the same time...but this one was the rare exception that missed on both points. Note: Impact wrenches create tremendous HEAT when you engage the the fastener with a socket for an extended period of time (> 1 min) at high torque ratings which exceed 1000 blows per minute. That withering heat will tend to breakdown the tensile strength of the steel faster by 50% or more causing it to eventually yield to any twisting or hammering force being applied. If it fails to twist for whatever reason, it will eventually snap off the bolt head. So it just becomes a matter of time before the fastener fails (snaps), if enough heat can be generated in that short time frame. (when combined with a high BPM being applied by the impact wrench anvil) Progressively larger diameter bolts (of the same grade) will require more torque, and time, to achieve the same result.
What a stupid comparison. U aren’t using the same type 20v battery. The dcf 899 has a 5 Ah battery in it and the dcf889 has a lower Ah battery. You can tell by the labeling on battery. Why don’t you do your little test with both tools loaded with the 5 Ah battery so you give people an accurate comparison.
I looked up the DCF889 specs online, it only tells 400ft-lbs of max torque? damn, that gotta be fastening? or both, no where Dewalt mentions the breakaway torque!

7:11 when the video starts

Because he says he's going to squeeze puppies
Two wonderful tools if you ask me!!

How has the 889 held up? Just ordered one hoping the breakaway is higher than the max 400 they advertise.
i saw the nuts spinning in the vise with the 889 too
Just brought one today, can't wait to use it.... 18v
A salesman, Why don't you RUclips creator go to a auto salvage yards and start testing these impacts on rusty bolts instead of these new bolts, action speaks more than 20 minutes of words.
Because not everyone is as clever as you are. That’s a pretty bright idea you had.
Yeah because that's where real action is
...i'll bet the 889 would have sheared the M12 bolt if you used a shallow socket.
I think the GRADE of the bolt would be more important. Try M12 Grade 8 and see what happens. Good video.
I’m pretty limited on the size of bolt I can find in Canada ☹️. I just purchased a worx pegasus workbench but my first choice would have been the keter but unfortunately it is impossible to find in Canada 😩
both would have done it but if you watch your own video you will see the bolt turning in the vice, hence losing torque to sheer it
scott dephillips sr. good thing I did some more test and more video 😉
'hence'
Yeah he forgot to try the older one again because it was turning but had a new set up for the new items didn't turn it again with the older model the old one would do the job too 😉 lol he was all about the new one from the Start of the video if you asks me
Im buying an 899 but in 18v. I think both 18v and 20v have the same capibilities.
The 20v thing is just marketing by dewalt so yep all compatible 👍
Impressed.
Nice video
The short wheel socket would have been better than a deep roll socket
What’s a short wheel socket? never before I’ve heard that term. They’re called shallow sockets and/or either long sleeved/deep wall sockets.
had the bolt not have ground round in the vice. the 889 might have sheared it.
Shane Clews I don't know I was hammering in it for a while before it started tuning in the vice. I think compared to the Milwaukee HD 18 that extra 50 ft-Ibs may be the key.
Yeh I suppose it may provide the extra power to break the 8.8
Shane Clews the 899 add no issue with the m12 ;) now I just need to find an m14 and m16 to push the limits 👍
I look foward to the results
longer socket make impact lose torque
that's allot of puppies indeed
I tried to actively search for Dewalt 899 on yt, only found a few, the same for days, suddenly something happened and now there are huge amounts of dewalt 899 videos here on yt. Is this some kind of block against dewalt, throttling down their brand.
Who’s known 🤷♂️
Does this mean I have to register all my m16 bolts?
newton raymond I'm sorry that's a yes 😟 lol
I yes got one more video from you nice
Thanks. Bro from Dominican republic.regard
Would it be better to test with a torque wrench?
bill R Different test for different applications sometimes you need to sheer the bolt to remove it! So it is good to know witch impact can do it.
If you wanted to measure the bolt sheer strength, that would be one way to do it. But you can't directly use a torque wrench to measure an impacts torque.
Probably need to do a video on vice quality. 😉
Lol
Sorry for ultimate, the battery model dcf883 and dcf899 are same
Its hot? Wonder why🤔

diego h perez thank you I’m glad you like the video😁
Your first time using a impact gun
its not a drill its an impact wrench
Maybe on your next video you should change out that Chinese vise for a USA...LOL Video was very useful, Thanks..
lol You’re welcome
Yes my friend you’re the best friend thank you very much
You gota use the same amp batteries dude not a far fight
talk about repeating yourself,wow!
Are betteries interchangeable? 889 and 899?¿
song luc yes you can interchange them.
Well that’s not an accurate test the bolts already been hot so it’s weak

Michel Mateo Vasquez yes it is compatible 👍
where did you get the bits from?
theandroids the bolt are from home Depot / impact from Amazon / and the socket from Canadian tire.

some are more difficult then other to put on you just have to turn the socket and sometimes give it a smack to get on there.
