Our lifetime of TOOL RANKINGS : torquetestchan...
Today we open up the mystery yellow tool DCF961 to find inside it looks A LOT like the yellow tools you might own at home. Hmm, curious.
*IT TURNS OUT THE DUAL GEAR DESIGN IS JUST A COMPOUND PLANETARY* the sun gear drives the larger diameter and the smaller ones mesh with the ring gear for further gear reduction. Which makes sense as the larger diameter gears are helical. Seems thin for a gear spinining 3lbs of weight, but never seen it before on an impact so we have no idea.
*Can you swap in a 3/4" anvil?* Unfortunately not. This one's anvil is very long from the nose cover thickness and gusseting. An existing 3/4" wouldn't even poke out.
We think the 1/2" anvil on this example (mixed with how clunky & jumpy this brand's impacts are) holds this tool back more than you might expect. It's like a fire truck stepping down to garden hose diameter. Both this and the curious VTEC like behavior of it makes it, believe it or not seeing these numbers, not well tuned for our tallying. Looking forward to seeing more on this as we see it pop up in places.
Maybe I'm being dense but do you have access to any extended anvil 3/4"-ers? Like that IR 1" lithium you had. IR make 3/4 extended air impacts as well but idk if they're common
@@cian.horgan The problem is you usually need to keep it in the family. The DCF900 anvil fits in that hammer shape, but other anvils shape wise wont.
@@TorqueTestChannel ah yes there's the density, makes sense. Nothing a quick trip to a hacksaw can't fix, who needs carefully engineered harmonics when you've got BEENZ
The one-inch anvil tools come with dual-handle designs. Would the torque figures change if you pressed this tight onto the bolt [test equipment] using both hands?
It's got Vtec bro!
Plot Twist: Dewalt themselves leaked this so that TTC would test it, tear it apart, give feedback and then they'll release the improved version later this year.
I hope so
Theoretically possible, but if that was the case, it would come out next year, not this year.
Manufacturing is slow, especially if you're as big as Dewalt or Milwaukee or Makita.
Theyre sloppy with prototypes. Everything from cabinet jacks to blades to tools. If you know a sales rep or tool development team member it's pretty ez to get.
@@andrewilliams9705fuck yeah
They should have sent it to Shop Tools Reviewed also if it was.
"oh great I can finally get a decent unbiased tool review to see who I'll go with"
*channel accidentally starts a nuclear arms race between tool manufactures*
It’s worth it tho
Thinking about vibrations, you can get gloves with accelerometers to monitor vibration exposure for H&S reasons. They would be a good way to quantify exactly how violent each tool is to hold
Or do it how project farm does it
one thing is shaking, and another is kickback like makita does. and also another is just the pure torque. i think sensing it by hand is the most precise, because it is like the user will feel and not how sensors feel
I suspect this sort of 'arms race' wouldn't be happening to this extent if folks like TTC weren't doing things like this.
Agree totally
That’s funny…. Wait.. You’re being serious?!? That’s a silly thing to think. It’s human nature to keep pushing the limits, since the beginning of time. Why would impact drivers be any different?
@@savage6394 Economics and the law of diminishing returns comes into play here. We are not talking about climbing a mountain just because it exists. It's the same concept as concept cars. The boundaries being pushed are not always meaningful economically.
Agree. Think just 5yrs ago. Dcf899 was tops (in yellow at least) down about ½ power to this lol. Wild stuff. Competition breeds innovation. DeWalt got lazy, M18 handed them their butts, and now Yellow is reawoken. We all win.
@@Dustin2112 spoken like somebody who doesn’t understand the more power motto. Just because it doesn’t make sense to you doesn’t mean it shouldn’t be made.
Great testing as usual.
Do I NEED it, no
Do I WANT it, yes.
😂
As soon as I seen it I was like I just got the 900 in December now this comes out tempting me.
@@a1racer441 TTC said it best "This is not a replacement for an impact wrench. It's the 'store in the bottom drawer, only take it out when things get apocalyptic' sort of tool." IMO that description fits this tool the most. I just bought a DCF-900 because they're on sale for $299.99 at lowes and I couldn't pass up that offer. Especially because the 961 is $370.
@@Asmith-1111 the 900 has been awesome though I have zero complaints it's a beast.
@@a1racer441 I haven't had the chance to use mine yet, but considering that my first big impact wrench is made by Kobalt, I'm excited to get the chance to use the DCF-900.
I think DeWalt has been watching and paying attention. 😊
I think the same...they get the products right it looks like they watch the channel👍
Glad to see DeWalt was tired of being in the middle of the pack with their impacts and just decided it's our time to shine.
Power wise, yes. However, they look like a pain to use. If I needed one of these everyday, I'd buy the Makita XGT 3/4 inch
@@luisprieto4589 oh definitely I have the 900 and it's a handful but it does get the job done faster so I don't mind too much. Would not recommend using all day on any high torque especially if you have to use on a ladder like I was. Really hope they offer it in 3/4 and maybe in the future a one inch 60volt version.
They are stepping up their game and I have recently jnvested in them buying batteries and 891 and new flexvolt 416 grinder, however, their brand is a big chaotic mess. Milwaukee is a better brand over all, higher quality and more consistent with everything, though every single motherf*r and their dogs sisters brothers cousins nephews wife's kids uncle literally have Milwaukee, and I'm sick of looking at, I thought I'd get the few DeWalt tools to suit my needs for my job which happen to be better than their Milwaukee counterpart. And go from there.
That's a compound planetary gearset. The sun gear on the motor engages the large diameter of the planets, while the smaller diameter engages the ring gear. It gives additional gear reduction.
kind of like a differential in a car?
Yeah, you're getting a gear reduction in the planetary as well, but the observation that there is less surface area to move that weight is spot on.
@@n54single I guess so think of it more like using first gear and the diff is the second reduction..
@@brettwalkom948 well first gear is a reduction gear but by no means a planetery gearset. but a diff i think is a based off a planetary gearset
@@n54single it's still a reduction.. I was just simplifying it.. diff is also a reduction hence double reduction
Wife: Why do you have twelve 1/2" drive impacts?
Me: I dont know.
Fixed answer: Cause there isn't any good 3/4". That may change this year.
I have 5 for now lets see what comes out next lol
Also me: (quietly to myself) that you know of...
In regards to your constant video releases, I think no matter what content you decide to go with it will be a good watch. With TTC its not about what youre doing, it's the delivery in which you do it. From your wrench videos, to your lights and cut off tools, you offer a ton of very useful hard facts about the products you use. This I feel is the draw to channels such as yours and Project Farm, a huge spread of realistic information that can be either useful or non useful, but due to this caters to a large variety of viewers. If you stick to your deliveries I feel youll continue to make excellent content that helps many people.
Hey dewalt corporate: don’t hunt down the person that leaked this product. Give him a promotion and a raise. This right here is building anticipation for this product to release. I’d expect them to fly off the shelves and be hard to keep in stock.
So how do you know this wasn't dewalt doing this themselves? Free advertising except the cost of some mail.
This reminds of the "stereo wars" in the 70's. Pioneer and Marantz going back and forth, producing MONSTER stereo receivers. Then Technics came out of nowhere, with a 330wpc monstrosity to settle everything! 🥴
Carver made some beasts too.
@@Comm0ut Yeah I've got one of his Sunfire amps. Think ours is 200 wpc but I know he made some 400 wpc as well.
@@Comm0ut Those were commercial amps pretending to be consumer products.
So that means the random Amazon impacts are like SounDesign and Coby?
Dang, just bought a DCF900 after I saw your review. Now I need to wait for the DCF961. Pretty excited.
I'm lucky, my shop buddy carries the "red brand". We use both pretty often. This has been a fun ride, none the less. Thanks for sharing this data!
I wonder what this tool would do if it could take advantage of those 60 volt contacts 😈
We did expect a DCF961 to be flexvolt, curious why it's not. Probably easier to re-use the electronics from the latest XR model
@@TorqueTestChannel I'd keep an eye out for one of the larger anvil sizes to be Flexvolt because this gun feels like it's the start of a new generation for DeWilt. If I had to guess they're probably going to go the 1" anvil route with the same hammer and they'll prefer that FlexVolt battery since more voltage means more motor speed, and more motor speed means, possibly literal, wrist breaking torque with that three pound hammer
You guys are unreal! Nice to see they did make some refinements to their guns, and the regular, smaller, lighter 5ah only loses 5%.Thanks!
To think it all started with an old school half inch and a home made dyno !
The shame we had as Dewalt guys a couple of years ago with their previous generation is no longer!
what generation? just getting in to dewalt,, is the specific stuff to avoid?
@@charlieward7606 All of the recently released stuff is great. Also, the 3-mode switch on the new Impact Wrenches is so awesome, you'll never want to use anything else. Check this site's reviews of anything you consider buying to make sure you don't get duped into buying any impact wrenches from their previous generation.
@@SvdSinner thanks man, yeah im a mechanic, the dewalt impact is one of the reasons i went dewalt ahaha makes some weird noise but looks good for crank pulleys and i aint got snapon money xD
If its 2 pounds and moves up to 3 pounds, that is a 50% increase, not 33% increase. You compare the difference to the starting weight.
I heard the collective cheer across the world when that sucker hit 1000!!!
Love the simplicity of the hammer/weight to increase power.
I just wanted to say that your channel is one of my favorites. If I'm looking to decompress and turn my brain off from all the stresses of daily life, it's great being able to tune into a pure review channel that isn't bogged down with countless gimmicks or thinly veiled sponsorships. No current events to stress over. No host trying to present some nonsense personality quirk attempting to differentiate themselves from the sea of other "quirky" hosts. No fluff, clickbait, or trying too hard with terrible jokes. Just a cool breakdown of how power tools perform with amazingly detailed explanation, no frills but also well done videography, and technical information coming from someone who obviously has a wealth of experience. I don't know why it provides such a great mental escape for me, and if you explained it to someone it would probably sound very boring, but it's not. I don't even use impacts very much. I guess it's like listening to wave or rain sounds.
Anyway, this entire comment probably sounds like a backhanded compliment, but it's definitely not. I just wanted to say keep up the great work and I appreciate the work you guys do!
My DCF900 already barely fits in my toolbox. Guess I’ll have to get a new box when this does come out.😂
This is the way
The 900 it's a beast already😱
I would LOVE to see it come out as 3/4 with a handle option, like the 999 sorta
Makes more torque than any Honda! 🤷😅
definitely more than a prius
Can't wait to pay $700 for it on the Mack truck.
Wow dewalt is back Taking everyone's lunch money trying to compete with everyone.. So very nice to see dewalt competing and making better tools
I really hope they make this in 3/4 drive. I was about to replace my dcf899 with the 900 but this would be even better at work. I have the 891 and I love it. More than enough for the lighter duty stuff.
This! I can't imagine your 1/2 sockets last very long on this new tool.
2025: 4lb "sledgehammer" version.
For the accelerometer stuff, measuring that in a real, meaningful way is going to be a really big pain or expensive. It has to be attached very rigidly, otherwise you won't really be detecting the true acceleration of the battery. For a small accelermeter, like what's in a phone, it wouldn't be too hard, but that kind of accelerometer (capacitive MEMS) isn't going to give good data since they generally top out at around 400Hz. Obviously for what an accelerometer in a phone is used for this isn't a big deal, but this use case is very different.
This is fits into what industrial accelerometers are used for, but are also way larger since instead of using some microscopic MEMS magic, they generally use piezoelectric crystals instead. This gives them a way higher max frequency (10kHz+), but reading most off-the-shelf industrial accelerometers is a pain without the proper equipment. Most of them are also large enough that I think the extra mass of the accelerometer along with the mounting for it would probably end up changing the vibrations noticeably, especially on smaller batteries.
We've actually been looking for small accelerometers we could mount in different parts of paper machines to monitor bearings for my job, and the smallest we've come across that doesn't require a bunch of extra analog electronics to deal with the signal and has all 3 axes is the TE Connectivity 830M1 series. They're about 0.6" x 0.6" x 0.17" and just output a voltage proportion to the g-force for each axis. You might be able to superglue it upside down onto the battery and then solder wires on to the pads on the bottom to run them into an oscilloscope for testing. Let me know if you want help with that stuff, part of my job is designing industrial electronics.
Sounds like a great place for a Chinese flex PCB. Dead bugging a leadless package is delicate work and quite fragile.
a fun thing to do would be to test tools with a power supply instead of a battery just to see what the theoretical max torque of a given tool is.
These batteries are actually much more capable than most power supplies. You’d need an insanely large power supply to match.
Power supplies are also not usually great at sudden changes in load.
A custom battery pack with 4x the cells would probably be best.
they tried that before. it's worse . batteries can provide more power quickly. yes a large power supply made of batteries with big cable might work.
Please make a video on the Swench, it's a manual impact wrench from power hawk technologies, it should be really interesting to see how it goes!
I have never clicked so fast
Just know that if you have an old 18v DW059, you can use Dewalts trade up program to get this beast for like $150.
At what point do the 1/2” sockets become the weak point with 1000 ft lbs?
For an accelerometer, go with Kistler Instruments. Piezoelectric (so you need a charge amp) but they offer brilliant pre-sales support (I used to be a UK sales engineer with them) Not cheap, but you will be analysing everything once you get one!!
Dewalt : vtec just kicking yoo!
V- TEC kiks in : yoooooooo
Bolts: 😭😭😭
You know you want to 3/4" swap it...
I second this idea! 3/4 swap it! If you can, without damaging the tool.
Dewalt just dropped the Nuke and told them “kill’em all and let God sort them out”. Me thinks Dewalt got tired of the Milwaukee Myth.
Would be awesome to see you test a Indy or nascar 350psi impact.
dewalts definitely been upping their game the last couple years. I hope they come out with a new series to compete with the Milwaukee's m12 series
The dewalt 12v impact wrenches are stronger then the m12
@@FusionBoost2.0 was about to say they already did lol.
@@SouthJerseyBaitReviews he missed that video🤣
@@FusionBoost2.0 I meant with how compact the batteries are
@@doorlessmoon2886 the slide packs have not really affected anything... And the compact style batteries in the Milwaukees are useless really, you need to run the bigger packs which negates it being compact
I would be interested in seeing this with the cheater sockets you reviewed a while ago. Just max out them beans!!!
Great analysis and testing. That said, I wouldn't use a 1/2" impact at these power levels as it's going to beat up and destroy my sockets. Definitely hope this is 3/4" when it comes out. If that's the case I'll hope it lands at closer to 1100 ft lbs in final form. As a retired auto tech though it's rare I need anything beyond a standard high torque 1/2" on a vehicle.
As a side note: that was pretty amazing you had two different impacts land exactly at 1000 ft lbs. I mean the odds for that to occur have to be pretty wild.
I’m a dewalt guy all the way and I really hope to see more on this Ludacris impact wrench
Dewalt take my money!!!
Great video as always! Would love to see this beast with a 3/4 anvil swap.
I would bet your channel has been brought up in a few board meetings!😂 love to be a fly on the wall for that!
Since the anvil is swappable with the DCF900, curious if the DCF897's 3/4" anvil would drop in
This impact going to take the wife, kids and you're lunch money 🤣
Power stack is the ticket !!! They have tested batteries and it beats all of them.
If you're going to measure acceleration on the battery you'll need to also build a linear accelerator to slam the batteries to a stop so you can establish how many G's it takes to damage the packs or the batteries in them. So an air cannon with a sled down a pipe. I can't wait.
its pretty clear Dewalt is willing to trade operator comfort for shear torque numbers, which ONLY makes sense for prosumer type users, You run one of these all day and you will require Makita smoothness. An integrating accelerometer mounted on the handle would allow you to score the amount of discomfort they design in and maybe dissuade them from this tradeoff.
Honda would be proud
VTEC!!
I love this channel.
If you are looking a cheap starter accelerometers plenty of people have hacked wii remotes to give output values. While it wouldn't look pretty it could give you an indication if this is an area worth testing and what sort of results to expect. This could also inform what grade of meter you need. I have just purchased a DCF880n and would love to see it on the dyno if you get a chance.
If the dogs are the same size, is there a 3/4" anvil you can swap in to test?
This is a good question and i'm surprised we didn't address it. Unfortunately not. The nose cover size and thickness from gusseting makes the anvil itself super long on this, a 3/4" anvil from another DeWALT wont even poke out past the nose cover.
@@TorqueTestChannel Lets hope a machinist is watching and makes you a 3/4 long nose anvil.
@@fluke196c It has to be forged usually from a high nickel chromium alloy, these just get absolutely brutalized
eh, testing an unauthorized procured prototype part from a company that makes 1.8 billion a year is playing with fire my guy.
as much as I like testing, this is a fire that's gonna burn you.
I watched this video when you first posted it and you always deliver awesome content of course. I just got a email from harbour freight about their new Bauer high torque impact with a 3amp battery. Just hoping you shed some light on the real torque specs! Always watching. Much appreciated!Thank you!
I hope they make this in a 3/4 inch anvil, or at least have selectable power modes... Otherwise you'll be wallowing out every socket you have. 😉
this channel is starting to impact (pun intended) the field and i love it.
I love the quote that “we don’t reply to any emails from them” inferring that they may have sent an email to take your vid’s down on this unreleased tool that you guys blatantly ignored
I've been watching for a while and it is amazing how far we've come in cordless impacts in a year
Love seeing you roast the Honda boys🤣
"Brooooo the VTEC just kicked innnnn"😂
Well, I was right 1000ft-lbs....but just lol
Can't wait to see more on this oddity of a tool. I have found that with my other Yellow impacts that when putting a good amount of pressure on the back of the tool it will remove stuck bolts that were unable to be removed in any duration of time while not putting pressure on the tool. I would love to see how much of a actual applied TQ difference there is when the tools is able to be wrangled in a little more.
Can't wait to torque to spec oil drain plugs in the shop
This thing is a monster.
The one-inch anvil tools come with dual-handle designs. Would the torque figures change if you pressed this tight onto the bolt [test equipment] using both hands?
I would have liked to see what the XGT's battery looks like on high-speed.
Impressive is this DeWalt DCF961 1000 ft lbs more juice than the Makita, i will still stay with Makita for the reason you pointed out it is put together little better and Makita is balanced better, i made this comparison with all the brands i tested, Makita came out ahead for me overall, I have Carpal Tunnel in both hands and the balance /comfort from Makita got my purchase and never a warranty claim with any one of them i own yet, I just wish they made a cordless ratchet as descent as a Milwaukee unit/units, in the meantime it'll have to be air powered for now, Hats off to DeWalt for bringing out the DCF961 BUBBA Impact of cordless wrenches, wait'll i tell my nephew about this ,he'll go place on order on Monday morning 😂
Impressive! But the 3/4 XGT is still a better tool for actual use
I’m excited for the direction you all are potentially pushing tool makers
ADXLs 345 would work fine, probably wouldn't be too difficult to setup with an Arduino (I've only run them off pis). But they're fairly precise accelerometers and definitely small enough to bolt onto most batteries.
We need to see the makita 3/4 xgt (well all the xgt's) with the higher ah batteries. I've tried the 5ah & 8ah. The 8ah makes a massive difference, use it mostly on m20 bolts for changing Shredder blade's and if the 2.5ah doesn't move it the 8ah does, even though the bolt is destroyed in the process
I think the power output of these will see an uptick of upset mechanics with buketfuls of snapped or cross threaded bolts.
I Hope they do release it in 3/4, I'd like to have one for those rare very tight bolt instances, I'd rather step down to 1/2 than step up to 3/4, since when stepping down the lost torque wouldn't be so bad.
After very little loose my dcf961 broke the anvil internally. Though the nut was tight, it was a lug nut on a honda accord. Sorry Dewalt but can't recommend... definitely a monster for the short time it worked.
Oil mechanic here im seeing if you can do a review on pneumatic 3/4 impacts my pawn shop husky is dying... should i go IR, or snap on? Matco currently has theirs for 940 on sale??? Review or opinion? Thank you bro im getting a dcf900 soon
Wow, the sacrilege of taking apart a Dewalt with a Mikwaukee. Its like having a Ford tow your broke down Chevy. 😅
EDIT: Wheel studs and similar type things will become hard to get as those manufacturers get rich -> from all the broken and stripped bolts and studs that will become commonplace as these impacts hit the market.
Am I the only one that let out a loud “YEAH” when the dyno hit 1,000 for the DeWalt? 😂
Nope. I did it too.
I think the power stacks have a lower internal resistance vs typical lithium cylinders like 18650s. So I think amp for amp, it'll show less voltage drop. This will change if we see Tesla's tables design enter battery space. They will probably dominate.
This needs to come out so you guys can do whatever crazy thing to one in order to double the input speed and start shearing anvils like toothpicks (coming from a member of the red camp)
You need to hire Dwayne Johnson for the new Dewalt.
Look into piezoelectric pickups to see the vibration waveforms.
Could you test the Fein ASbe 648, it is powered here in Germany at 230 volts. A good old machine. I like it a lot and it busted a lot of bolts in my life. Just for the Fein tool history. It says it can do 400 nm. But I know it can do more. Or my do more 😂 so a small old school power tool test
Jeez….. 1000lbs. You may want to invest in some sort of blast shield. I would be afraid of something violently exploding at that torque.
Thanks for saying "vibration DAMPING." You win the internet/language points today!
Lol if it carries a secret/codename it must be *Goliath* , just laying it next to anything makes it look like one of those fun-house mirrors where your friend looks like a giant, and you (I) look like a mushroom cap 😂
As you guys start testing battery movement are we gonna get to see how a batt strap plays into it all in high speed? Would love to see it.
it's been my experience with a powerstack on my MAC TOOLS 1/2 INCH impact that the powerstack sags in output after 1 bar of battery use
They're making the tool more robust, and possibly adding in a lower speed setting for lower torque applications, because it's easier than designing the thing not to shake around like it's in a Benny Benassi video?
You say you accept no sponsors, but I remember a video where you said you were going to be working with Astro Tool maybe? It was some company like that.
Realised the Idea of the accelerometr and Gyro with a cheap arduino Chip and Code sadly i dont have the Code anymore but im pretty Sure there ist someone Out there capable of programming this, Just an idea
I'm still using a 899 day in and day out when this is available to purchase I'll upgrade I just hope it has the longevity of my 899
Looks like 950 to 1000 is the max range. The batteries just change how much torque is under the curve.
Ya, so just threw both arms up when it hit 1000... at work break time at my engi-nerd pc. Then looking around, I don't think anyone saw me.
i just got the dealt mid range gun. 600 ft lbs . it's really powerful. 190 bucks so not too bad.
Going from 2 pounds to 3 pounds isn’t a 1/3 increase. You start at 2 pounds and to get to 3 it’s a 50% or 1/2 increase. But if you start at 3 and go to 2 it’s a 1/3 reduction.
Still looking for a 2 stroke 250cc dirt bike engine powered mega high-torque impact.
I choose to believe that dewalt and milwaukee were golfing one day, talking about market shares. Somone from milwaukee made an offhand comment about how someone has to be second at the same time as teeing ahead of a dewalt engineer whose name was before his on the paper. The engineer laughed it off. It was late in the day and everyone else called it early and went home but not the engineer. He went to the workshop.
