Let's take a slow-mo peak inside air tools and cordless impact wrenches and impact drivers to see how they work. Even if you already KNEW how they work, it's pretty cool to see it first hand in high speed video we think!
Torque of TTC is working in product development for Astro Tools who also make impact wrenches (air). TTC is not the only testing out there, always consider multiple sources when looking at a tool!

hi so Milwaukee and Ridgid use the same parts ??
@@jay-od7kh Sometimes, not often interchangeable.
I'm just here to say it's not about speed when it come to auto machine I only use power tools to take nuts and bolts off.. they dust collector in my tool chests.

I love channels that invest the sweet, sweet RUclips bucks back into things like high speed cameras, giving us even better content 👍.
True now maybe you should invest into the Chanel (merch) because I bet they'l love it

There not many
A high speed camera is worth about three lifetimes
I’m so amazed how the hammer feature doesn’t wear off quickly
get a Ryobi and then you'll find out how fast it's done
You mean wear on the hammer surface? It's easy to control with electric designs as the motor is only going to put out what it puts out.
(Well, unless you're like me and wonder what happened when you put 120VAC to a12 DC motor, lol)
Air designs you could theoretically over-speed, but most air systems are standardized.
You mostly run into that problem in hydraulic powered tools as small changes in flow make big changes in power.
Id make a new 1 at work myself , those tig welds on the 1 look small but clean ,probably robotic
I love these videos, especially the slow mo, and getting inside and seeing things work is what drives me to want to learn more.
I know to come here for impact wrench reviews. Look at just how passionate this guy is. I'm very impressed!
This is an excellent video and when I was 21 years old and in junior college and taking engine rebuilding we got to learn how an impact wrench works. This video goes into great deal on how it works and gives one an excellent illustration of how it works. Thank you.
Fascinating stuff there. I recall in my high school physics class the teacher explained how angular momentum could be conserved in elastic or inelastic "collisions" of rotating shafts, but I could tell he was having a hard time finding any examples of this - here we have it! Now planning to become a high school physics teacher myself I anticipate I'll show some of these clips to my future classes. Another cool thing about the physics here is that some of these have the hammer bouncing back rather than simply stopping - that actually increases the momentum transfer as there is greater momentum change (going not just to zero but negative). And the spring doesn't just push the hammer forward, it stores energy then will spring the hammer forward potentially faster than the motor.
This comment should be pinned .02
For your brighter students, I'd introduce energy methods for solving collisions. Basically, the "torque" you get out of this thing is actually rooted in the kinetic energy stored in the hammer and dumped through the anvil. This one isn't conserved, there's plenty of waste going on, but enough makes it to the shaft to be very useful. Anyway, since everything is basically a spring, you can store energy throughout the whole system just like when using a spring. The relationship is linear as well - it's just Hooke's law. Where things get interesting is what happens once static friction is broken. Whatever energy is left after tensioning the entire system up to its point of either yield or maximum allowable static friction has to go into causing "permanent" rotation or deformation.
Showing some of the high speed video will demonstrate how every hammer blow adds just a little bit of rotation to the fastener, which gets smaller as the video progresses due to more energy being required to overcome the static friction holding the thing in place.
This might be a good introduction to energy methods for impact analysis, should any of them wish to take up mechanical engineering later on.
10 seconds old and 10 likes? You guys are bananas
Keep up the quality/interesting work, and just wait 'till you see what happens when you get to 1MM subs!
You're the best
I'm no psychic, but I smell a ProjectFarm collab in the future.
ruclips.net/video/xQzqNnWG21s/видео.html 8:42. forgot to remove editor notes. Just fyi
@@af099 haha we dont have an "editor". That's a card telling you we're clipping the footage to save you 20 seconds of me just flipping the Milwaukee from forward to reverse. An example of how something that took 0.5 seconds is 20 boring seconds of a slow moving thumb :P Did spell "forward" wrong there though, like a real smart guy.
Very cool to see these in action. Thanks.
Thanks FarmCraft! Enjoy what you do as well!
Retro-engineering is just the best science ! Disassemble and understand its operation is so satisfying to me ! Ty for this one, wish you the best !
Why does this channel not have a million subscribers. Dude you’re killing it
Not many people like us left, Starbucks crowd is taking over.
@@honchoryanc I love Starbucks but I also learned to wrench on stuff as a kid. This is incredible we get this type of info and content for free

World's most overused comment goes to Caleb.
@@svn5994 don’t understand but thanks for piping in
Once again, I learned something new. I never even thought about the mass difference between the air and cordless hammer drills before. I will say, however, for screws and even some mechanic operations, the cordless impact is much more convenient, but I know when to bring the big guns (air) out.
I love how you don’t just show us videos but you teach us as well.
The algorithm brought me to your video, I had ZERO idea this is how impacts operated. I've had my milwaukee impact for almost 7 years, abusing it every day for work. Seeing how it uses a rotational hammer and anvil is even more surprising since it's still kicking to this day haha great video🤘👌
This is the best video you've done. Although being a 25+ year mechanic I've never fully understood an impact until this video. Thank you
Very true !!!
Learning the whole different theory of operation with cordless (or corded for that matter) over an air tool was cool. Nice work
thank you for showing me what is inside my IR air impact. it was really neat watching it work in slow motion.
I just watched your video about torque loss while using adapters and immediately recognized the love of the scientific method. No surprise the second video of yours I watched openly discuss the "for science" ethos you have. Love it, thank you so so much for making this information available to the world. This is very special work you are doing!
Incredible video, probably the best one out there showing and explaining this topic!! Very, very thankful for this! You all are doing God's work! I've become a subscriber.
When I first bought my house, I used to frame walls and things with a hammer and a bunch of nails. Then I discovered impact drivers and construction screws and now framing is my favorite job to do! I have an electric, corded driver and its so good at sinking construction screws into 2x4. And every screw pulls things together more and more. Unlike hammering nails where you are tightening the one you are hitting and loosening all the rest.
Great content yet again which is to be expected from you guys. This explains n shows what the different hammers n anvils are doing better than anything else out there. Thanks for all the work you guys do to bring straight up honest content to us, the consumers
I really dig this sort of content, and appreciate you're not using clickbait titles/thumbnails.
Great job on the video! A point of clarification when speaking about fastening, dynamic torque refers to a fastener being driven at a relative speed while in continuous motion. An impact tool by design drives the fastener with strikes and pauses which requires the fastener to overcome static friction each time, stealing a portion of the applied energy away that was intended to developing the clamp load needed to properly secure a given joint. The up side to impact tools is that they reduce the reaction force felt by the user allowing for for higher torques to be achieved without the need for torque reaction devices! When joint loading accuracy is of the utmost importance a DC electric fastening tool is the tool of choice as it tightens in a truly dynamic manner! Lastly, we can limit the negative impact of the variation in friction of a joint by using a torque + angle tightening strategy as it relies less on applied torque and more on mechanical rotation to drive the fastener!
I used impacts in refineries and I never realized they worked that way. Great video!
8:42 FROWARD! Let's all go FROWARD!
This has become one of my favorite channels. Great content guys, keep it up!
THANKS for Showing how it Works, nice. Greetz from Germany
Thanks heaps guys! Your new high speed camera looks the best of all I get to see on youtube. Staying put here for your acquisition of a F1 hammer!
*Because... SCIENCE!*
*You consistently put out awesome videos! THANK YOU!*
This exposé has real impact. Awesome.
WOW! I always wondered how these impact drivers worked...very informative and entertaining! Incredibly well-done!
First time watching any videos from this channel, but I wanted to tell you, job well done! I thoroughly appreciate the meticulous detail you had explaining this. I'm excited to watch all your other videos! Definitely liked and subscribed!!🤜🏻🤛🏻
Very professional! It's really a lot of work to create a video like this, I appreciate it. Thanks very much!
I do trim carpentry, but I love this channel! Great to watch with my boys.
Superb display of how these actually work. As an ASE Master Mechanic with over 30 years' experience, I still use shop air except for interior and 1/4 drive work. I love my Mac Racing 1/2 inch twin hammer air guns which are about 20 years old now. Even with hard daily use they only need seals and anvils about every five years. While other tech's use battery power almost exclusively, I drag the hose around for two primary reasons.
#1 The air is there and it has zero (0) effect on my commission. Shop air is expensive for the shop, but free to me. I've never asked the boss to buy my batteries, but I'm sure someone has and they still don't. New batteries work well with daily cycling but they still run out of power a lot compared to the compressor which has a worst case down time of 1 day every 15 years.
#2 Extreme and unforgiving power. In the real world, we don't use the recommended 90 PSI. That air hose has 130-140 PSI. I know when I put a massive socket on my gun and put that socket on the front crank bolt of a Lexus, two things will happen.
The gun will leave unless I hold on very tight with both hands and the bolt will come out. It always works.
Awesome video!
Phewieee!!! I rewinded - fast forwarded - repeated - played backwards and I still have no idea what this impact wrench does, but it sure looks cool.
Didn’t think I would be using a torque test channel video to study for my AP physics test, however this was surprisingly useful
This is the best/most important youtube channel in existence. You should do an episode on 1/4 drive ratchets.
Snappy 72 vs Gearwrench 120XP vs Harbor Freights finest vs Amazon's top rated!
I like learning about what I'm using. Half of the science made sense to me. Thanks!!!
Your attention to details is outstanding!! Thank you very much!!
Love this channel, between this and project farm it really gives you the foresight to get the best for you money keep it up guys
Simply awesome Sir.
I love videos like these.
Fantastic! Thank you for filming this. 👍
Amazing video! Impact drivers: incredible engineering.
I would’ve like to have seen the paint lines on all sockets also during the super slow mo (just to see the normal rotation of the socket vs. the hammer/dogs rotating)
Great video! I love my Snap-on and IR air impacts but also love the convenience of my Milwaukee 2767.
Very Knowledgable !. i'm impressed. And thankyou .
I will take my air tools any day when in the shop. When in the field, the cordless tool are hard to beat. Horses for courses.
This is the best informative video on impacts I've ever seen, really appreciate it! Personally I run air whenever possible. Easier on the hands, faster, and much more manly vroom vroom. Cordless is great when there's no air available, or you're inside of a bin, etc.
They're actually getting better than air..
@@3nigma.3nc anvil speed, torque vs weight, reliability...
@@-tr0n cost too
This makes me realize something. Sometimes after running an impact the anvil is stuck and won't turn till I hit the trigger again. That is probably when the hammers have slid on top of the dogs on the anvil rather than just engaging. Always wondered what caused that bind!
Brilliant video ! 👍
Wonderful video.
Congratulations on the high speed camera purchase. Should be able to have fun with that.
this helps me understand my tools better. thank you
This is the kind of content that deserves to get paid for. Useful and not trash that any loser can make like 99% of the rest of the content out there.
You really do have to see a hammer-drill in action to understand it, it seems. I tried the wikipedia page on them, and it didn't click until i watched this. Thanks for making this video. I learned something today.
Very interesting. I have wondered for some time how an impact works. I have used them for over 30 years.
Brilliantly Explained. Thanks
Fantastic video. Super clear explanation and video , with a pleasant non rambling speaking voice , a rarity on RUclips .
here's something interesting you might not have heard of . In Germany , where i live , i had a log style house built six years ago and noticed during the construction of some structural beams that the workers were NOT using impact wrenches on large screws . They said it wasn't allowed . The reason being that the impact action tended to ream out the holes in the wood when the screw is being installed .
Yeh, that makes sense. These things aren't exactly torque limited (like yonder Makita drill, for example). They deliver a fixed amount of energy (per ugga-dugga). While the screw is going in, that energy goes into driving said screw a little bit at a time (but many blows each second). Once the screw is fully seated, that energy still has to go somewhere. It's not like the torque-limiting clutch on the drill, where a bunch of spring-ball detents just let go (though that makes a similar sound), this is a big hunk of metal spinnamathingin' like crazy one moment and coming to more or less a complete stop *through that screw* the next. Where wood is concerned, when it can't cut it'll just shred.
Really really interesting, and very well explained. I never knew, I thought it was some kind of in-line hammering. Thanks!
Always cool to see how stuff like this work
Good shots and info, Keep it coming, and THANKS!
Thank you!!!! I've always wanted to know how a brushless motor actually works. Very little videos on RUclips on this subject.
Great channel i always pull up these videos to put down some erroneous claim from a co worker like and im not kidding you. Bosh is just as good as Milwaukee. Dude said it with a straight face and still stands by it for every tool they make even though i pulled up some videos of your of bosh getting obliterated by everyone.
Well power is out here so great timings on video
you guys are great!
Thank you very much! I learn so much from you guys! I really appreciate what you do!
LOVELY & BEAUTIFULLY EXPLAINED, THANKS BRO
Thanks for this very interesting video. I had no idea how an impact driver works. Now I know what I should look for before buying one.
You make great videos, very interesting and educational, also puts these companies claims and advertising to the test which is good for us i.e. their customers. Keep it up!
Nice explanation and use of high speed camera.
Really informative video - thank you for taking the time to make this!👍
Cool, interesting to see that it is such a violent mechanical process
Very clearly explained how this works. Always wondered (and somehow youtube knew!)
A great professional and thorough job here. I learnt heaps.
Neat! Thank you for all the free information.
Great job! Quality content as always!
Cheers guys. Yall nailed it once again
You did a great job by explaining the way how these devices work .a trillion thanks
Thank you for your great videos.
Very nice. I thought I had some of what's going on in there figured out. This refines it so thoroughly and without getting into formulae. That's interesting about getting the hammer to skip a dog so it has more time to accelerate for greater impact.
I used to split a lot of wood and I keep trying to tell the guys that want to show off their muscles - get the maul swinging faster with hand speed and quit trying to hit the wood "harder" which is far more tiring. Car 'B' colliding with a wall 3x faster than Car 'A' is hitting that wall 9x harder.
Wow! Love the science!! Thank you so much for the content and information. Cheers!!!!!
thanks for this clip. i thoroughly enjoyed it :)
Gotta love cutting up power tools.. um, for science! 🙌🏻
This video made a big impact!
I finally seen the inside of a drill I’ve been using for 7 years straight !!
How cool was that! 👍✨✨
It so cool and how it works. Thank you so much for showing how it works
very nice, impactful video
Thank you!
Another awesome video from this highly professional channel. 👍🏼
I would like high speed camera footage of money flying out of my wallet buying tools based on the results of TTC tests ...
Very interesting and informative vid!
Nice, at work we use that Milwaukee and some mixed Air ones (we also used to have some cordless Makita but they sucked) and while the air ones are ok, I still prefer cordless by far... just sucks as we just broke two of em xD
I especially love how its running way smoother over all, when screwing and no hammering is needed.
This is truly a mad science channel
Thank You!!! Very clear and understanding informative video!!!
Thanks for the lessons
Wow! Amazing video
Excellent video thanks
You deserve a subscription for for you dedication, if it wasn't for you, I wouldn't have ordered 7 impact wrenchs for my workshops.
I'm always fascinated by how you can put them back together again.
I'm not impressed easily, this video of information is simply amazingly informative as much as I know about mechanics etc I learned much more about impact devices that I've always wondered about !!! All the best to you and yours Sir.
