*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.

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 suspect this sort of 'arms race' wouldn't be happening to this extent if folks like TTC weren't doing things like this.

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

"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*

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.

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.

Great testing as usual. Do I NEED it, no Do I WANT it, yes.

I think DeWalt has been watching and paying attention. 😊

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!

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! 🥴

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.

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 would LOVE to see it come out as 3/4 with a handle option, like the 999 sorta

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!

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.

Wife: Why do you have twelve 1/2" drive impacts? Me: I dont know.

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.

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!!

Love the simplicity of the hammer/weight to increase power.

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.

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!

To think it all started with an old school half inch and a home made dyno !

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.

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!

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

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.

I’m a dewalt guy all the way and I really hope to see more on this Ludacris impact wrench

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.

I’m excited for the direction you all are potentially pushing tool makers

this channel is starting to impact (pun intended) the field and i love it.

I've been watching for a while and it is amazing how far we've come in cordless impacts in a year

Very cool. Vibrations would make it too much to use often, but it does look like a great tool to have at the back of your drawer for those days where nothing else works.

Hi TTC, I recently have acquired some of the dewalt 12V line of impact wrenches and ratchets. The DCF903b is the 3/8 impact I’m working with. I have yet to see a video that has your level of comparisons with this tool against its closest competitors and 20v version as well as the variability of the 12V battery options. Was really hoping to see it in action on your channel before I go buying different batteries or investing any more in the 12v line. Thanks in advance! *Edit: if you’d like to borrow it for testing I’m more than happy to share!*

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?

My DCF900 already barely fits in my toolbox. Guess I’ll have to get a new box when this does come out.😂

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.

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 use these types of tools daily and I am impressed by them but you guys do a great job making them so much more interesting

It's finally out!!! I've seen a few in stores yesterday!!!!

Great video as always! Would love to see this beast with a 3/4 anvil swap.

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.

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.

Thanks as always for the tests and ratings.

Love seeing you roast the Honda boys🤣 "Brooooo the VTEC just kicked innnnn"😂

I heard the collective cheer across the world when that sucker hit 1000!!!

The shame we had as Dewalt guys a couple of years ago with their previous generation is no longer!

Did you high speed video the Makita 3/4” to compare the battery vibrations? Looking forward to your accelerometer testing!

Just spitballin here could be cool if you had 1-2 batteries with leads coming off the terminals to display voltage during the run for each brand. Extremely cool and informative keep up the great work!

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.

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.

Awesome work as usual!!

Hey! Know you guys get a million suggestions but I think modifying an impact wrench to alternate directions between each impact would be up your alley, I've heard the tip of moving a seized bolt back and forth with a ratchet to help break it loose and I was wondering if it would translate well to impact use

Yes, I’m glad this come out when it did as there are a few heavy hitters releasing HT’s within a few months of each other and like dewalt, metabo hpt is also trying to make it as hard as possible to distinguish the new from old model 🤷🏻🤦🏻‍♂️ unfortunately tho the mhpt didn’t bring the beans quite to the extent dewalt did 😢 with their high torque models I I was quite excited to see the mhpt as I figured it’d be similar to the xgt 3/4 but no dice there on to the show

I would bet your channel has been brought up in a few board meetings!😂 love to be a fly on the wall for that!

it would be interesting to see the results of the heavy housing and the higher speed gears. please try it

Regarding the planetary - there are two stages in the newer versions gearbox - motor drives the three big gears in the planetary carrier (first gear reduction) and then the second stage is comprised of the smaller gears going around the ring gear, which causes the planetary carrier to rotate.

I'd like to see the vibrations tested. Wondering if that is why my large battery cases crack so much or if the plastic sucks and I can just never drop them. I use a digi-key m1528-1011-ND ounted in my car connected to my efi ecu.

Love to see that I’ve got a few of those 9ah flexvolt snow I need this impact !!!

Thanks for sharing guys, hopefully yellow dull that shake and bake down somehow. It doesn't seem to bode well for tool longevity.

Since the anvil is swappable with the DCF900, curious if the DCF897's 3/4" anvil would drop in

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)

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

This was published as I finished the other video and missed it. Was waiting for it.

Great info on these. 😎👍👍

I have a DCF900 that the battery is floppy on already. It connects firmly, but I guess the rubber isolators are already worn out.

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 would have liked to see what the XGT's battery looks like on high-speed.

I think the 3/4 could be a flex volt tool next with a 54volt motor powering that bigger ring gear maybe. It's would explain a lot of the design issues in this test model.

I wonder what the power curve would look like if they had a 'launch mode' where VTEC was kicked in from 0 ft/pounds, I'm guessing it would be right up there with the Makita.

At what point do the 1/2” sockets become the weak point with 1000 ft lbs?

Just know that if you have an old 18v DW059, you can use Dewalts trade up program to get this beast for like $150.

Thanks for this video, really informative. Now I can scoop up a DCF900 for a reasonable price, they are down to £158 in the UK. Just a note: no 6Ah or 8Ah XR batteries available in the UK only the 6Ah 9Ah 12Ah FlexVolt batteries (and the 15Amp beast).

I would be interested in seeing this with the cheater sockets you reviewed a while ago. Just max out them beans!!!

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.

I love this channel.

I think the power output of these will see an uptick of upset mechanics with buketfuls of snapped or cross threaded bolts.

Look into piezoelectric pickups to see the vibration waveforms.

With the massive amount of torque some of these things are making do you have any idea how much torque the anvils can handle? Might be an interesting test if you have the equipment to find the breaking point of 1/2", 3/4", etc. anvils. Maybe find out if any of the manufacturers are using different materials.

I love you channel -keep going!!!

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

Dewalt : vtec just kicking yoo!

Hey TTC, love the content you’re putting out. I really liked the Amazon brand 1/2” impact wrench videos and would love to see more videos comparing more Amazon branded tools, particularly 3/8” cordless ratchets and impact drivers, to see how they stack up with name brands

Thanks for saying "vibration DAMPING." You win the internet/language points today!

Dude, your narrations are hilarious. 😂

Great video! Thanks!

Very exciting, thank you

Great video thanks for sharing

Watching this video in particular, do those bolts on the either side of the machine ever come out from the vibrations?

Is their a Dewalt to Craftsman battery adapter? Their so similar

just a guess....but is that planetary set designed to be 2 speed? Just the second speed mechanism missing?

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

Could you test an aeg 3/4 high torque.

Would the new hammer assembly fit in the ridgid? 😅

i just got the dealt mid range gun. 600 ft lbs . it's really powerful. 190 bucks so not too bad.

Seesii makes a right angle impact might wanna check it out

omg this is beastly im going to try to get work to buy this for me!

Can't wait to torque to spec oil drain plugs in the shop

This is just a great channel.

I wonder what this tool would do if it could take advantage of those 60 volt contacts 😈
