Exactly How Much Power Are You Losing w/ Impact Drive Size Adapters?

[@TorqueTestChannel]

Something we tested yesterday just after making this is low-profile adapters like: amzn.to/3leaKL3 & amzn.to/3sAp0lE These lessened the huge 3/8" to 1/2" loss down to 10-16%, so it must have to do with the anvil being pushed out and away from the square drive on the socket, which doesnt help with that vibration either (see 2:52, the socket is a blur). Likely for the same (less) vibration reason, we also saw less % loss on weaker guns. For instance a 3/8" M12 stubby and our knock-off makita saw consistently less % loss, but still the same relationship between adapter types as in this episode. Torque who started TTC is working in product development for Astro Tools, always consider multiple sources when considering a tool!

[@xephael3485]

Torque rods work by actually bending and absorbing the impact... I presume all other adapters are subject to this as well as perhaps longer sockets depending upon the material they made of...

I just went down a 1.5hr youtube rabbit hole to find out if 3/8 square drive impact wrenches can be adapted to 1/4 hex, to save myself buying a "weaker" 1/4 hex impact driver. After sloshing through so many "cool" and "manly" fellas doing niche reviews, I find this. A truly genuine, no BS, channel devoted to presenting real information via the scientific method. In the first three minutes alone, you distilled far more important information than my entire rabbit hole. Thank you. Instant fan here.

[@caseofruns735]

How have you enjoyed your stay here

[@merlinfanboy556]

I went with a 1/2" one instead of 1/4" hex because I might not need the full power when driving regular screws but I absolutely will need it when changing the tires of my car. The max my impact wrench can do is 300Nm so plenty even with a bit of loss.

[@user-cs1ne8gx9u]

In industrial settings everything is 1in air hose and chicago fittings. Plant air is usually not anymore than 130 or so psi but flow is never a problem. Some of the bigger guns will use 2 1in lines, 3 men and a crane to hold the weight. Nowadays that type of work is usually done with hydraulic wrenches or super nuts. Great work guys.

[@fltchr4449]

I was looking a specs on 1" wrenches and they want somewhere around 50 CFM, compared to something like 5 CFM on 1/2" wrenches.

[@MrMartinSchou]

I wonder just how much force is lost due to fitment of the adapters. I.e. will a really tight fitting adapter fare measurably better than a loose one?

[@TorqueTestChannel]

We've tried 6 brands with no correlation so far, including Snap-On. Edit: Though if you're increasing rather than reducing, these seem to make a difference: amzn.to/3leaKL3

[@CarbonatedGravy]

Probably could matter, any kind of slop in fitment takes up some of the impacting force but also you can only make it so tight since you need to be able to get them on and off easily enough so the difference is probably very small

[@geojohnson5613]

Thank you for this video showing the results of using adapters on impact wrenches. This was surprising and quite informative. Now I know why the Earthquake XT 3/8" impact I recently tried was much weaker than advertised. It would not break my lug nuts loose which were torqued to 140 ft-lbs. I was using a 3/8" to 1/2" adapter on it. I found the advertised tightening torque of 160 ft-lbs to be 110 ft-lbs as verified with my Snap-On torque wrench. That's very close to the 27% reduction you demonstrated. Wow! I returned the Earthquake XT 3/8" impact to Harbor Freight and replaced it with a 1/2" Ultra Compact air impact. I have not had a chance to try that one out yet but I will definitely keep in mind the effect of reducers and extensions. I assume these adapters would affect an air impact wrench the same as a cordless impact?

[@CameronDC-Grimes]

Yes I haven't tested it myself but physics says extending where the turn point is, or having tiny gaps in connectors will reduce torque strength. I imagine the U-Joints for angles also reduces it quite a bit. I imagine a 3" reduces it less than 5" and 10" extensions. If you had a swivel/Universal joint socket on the end it could increase the loss by 0.5-2x depending on where it's at? (The nut/bolt end or directly connected to the wrench/ratchet/breaker) I have no clue how much loss there will be on combinations of different types of varying sizes and drive adapters used with swivel sockets/adapters

[@CameronDC-Grimes]

I also bought only ½" drive sockets and I'm getting a ½" dr Ryobi One+ HP 18v brushless Impact Wrench.

[@parkerdalo3248]

3/4 air would still be interesting. As you stated most people are not getting the advertised torque ratings due requiring such a high static pressure. The video would be a nice way to determine if the 3/4 is worth it over a 1/2 air even at the lower pressure. If the 3/4 air still gets a significant amount more torque, then there still might be a place for it in the tool box.

[@willc5979]

I currently work at fedex as a diesel mechanic. I was curious since I run my 3/4 snap on impact. Our lines are run at 140psi and it drops to 100psi. Our shop uses 1 Ingersoll rand compressor and the shop is large. By size it can fit about 24 single axle semi trucks inside the shop. I'm sure there are a lot of other heavy duty mechanics that watch your channel. Would be nice if you could one day test the 3/4in air stuff.

Overall I'm glad I bought the 1/2 inch because most of my sockets used are 17mm, 19mm, 24mm and most often are 1/2 inch drives.... the minority of sockets are 3/4 and even the bigger ones nowadays are made for 1/2 drive.

So In our shop with a regulator we run our compressor at 175-180 piped 120ft with 3/4" black gas pipe and roughly 400ft total for the 3/4" loop left right and center runs. At the regulator we can very easily hit 90psi dynamic pressure. The compressor is an 80 gallon Devilbiss compressor twin stage @15hp on split phase 240v phase2/3 motor rated at 25hp 3ph. The DeVilbiss 80gal tank is dated 1945 and has max working psi of 230. The First stage appears to be a 1970 twin cyl dual displacement vertical pump and second stage is a 1975 V-twin type single displacement pump. Its clearly custom or Frankensteined together to make the ultimate shop compressor. This configuration has been in operation since 1978. The max dynamic pressure we can hit at the regulator is 144 psi for about 8 minutes, 120psi for about 12.5 minutes and 90psi for about 15 minutes coming down to about 77psi continuous dynamic out of the system with an empty or equalized tank. We run 1/2" rubber airline to the tool.

It would have to be a good weld and insure everything is almost perfectly lined up. This is because i also believe that angles cushion as well.

When looking to see where the air pressure is dropping running large guns, i would be looking for the smallest diameter the air has to pass through between the air tank and the gun as that would be the weak link in the chain. The obvious thing i would change is that l when testing the air pressure i would fit a t-piece with air in-pressure gauge-air out so the air to the gun can flow as freely as possible. This would mean that you would still be getting the true line pressure rather than all the air going to the gun having to flow though the pressure regulator first.

Maybe you could do a test comparing losses to the tightness of fit. An adapter which is loose rotationally could absorb some of the impact energy. An adapter which drops more could perhaps cause the tool to wobble more. That would be an interesting test. Measure the maximum rotation or drop angle and the pressure applied at the maximum angle. Perhaps tape an accelerometer to the tool too.

I don't know that it makes any difference but the ones I got sit directly atop the anvil making it less of an extension and more of an adapter.

I think there is a video of that and I'm pretty sure there was a torque loss with the smaller fittings.

[@rufusconnolly8489]

There would have to be, the restrictor would have a faster flow rate but lower pressure so there a bottleneck b

[@z0mb13k1ll2012]

This is why I always just go with the 1/2" and adapt down if needed. The bigger fasteners need that extra torque sometimes. Especially in the north

[@Joethetoolguy]

📝 use multiple adapters instead of torque sticks

[@swayme67]

Once again, absolutely brilliant, fun, and educational. Please keep these videos coming!

[@chuy559123]

@Torque Test Channel I really enjoyed the scientific research done on this video. Rip to beans lost in this video. I know you guys do a lot of hammering on your videos, would you guys be able to make a video on a sockets durability comparing different brands like snap on, proto, icon, grey pneumatic, sunex, tekton, matco, mac, Milwaukee, Nieko, etc. to see who makes a most durable socket with all these beans you guys crank out?

[@hvguy]

I can really feel it on the small M12 using extensions. Great video guys!

[@georgeferlazzo7936]

Hello again Torque Test Channel Thank you for another Great Video. I would have thought Otherwise. But seeing it in action. Wow, what a difference. And this happens no matter how you set it up? Amazing, Again thank you

[@Parents_of_Twins]

Well damn apparently I need a one inch impact. Didn't realize how much that 3/4 to 1 inch adapter was throttling the gun. That being said there's always the torch if the impact won't take it off :) and it's a lot cheaper.

[@z0mb13k1ll2012]

I had to use my 1/2" m12 stubby with a 1/2 to 3/4 AND a 3/4 to 1" adapter to go onto this giant custom socket for some robotics work. It didn't need high torque, but was just a massive size. I found that due to the slop between the adapters the majority of power was being lost. After running it several times I noticed the adapters were very hot. Not an ideal setup for impacts, but for linear force it would be fine

[@merlinmagnus873]

Love that last one. Look up sketchy in the dictionary and it has a picture of that setup.

[@jamespeaden7862]

Couldn’t tell ya the numbers but at my work we have a duel 2 stage air compressors plumed together on 1/2inch line. With the 3/4 and 1 gun we can work about 3 or 4 minutes before we have to stop and let the air build back up. M24 sized bolts that are tightening to like 600ish pounds

[@seymoarsalvage]

HF has a new brushless Bauer impact. Think we will get to see that one (before I just go buy it lol)

[@joeellestad8912]

Could you run a test of 3/4 vs 1/2 with your current set-up and then another test set up as an industrial setting?

[@alexmills1329]

For the Engagement, it’s always a good video from this channel

[@Jay_Ira]

Now we need a culmination Science episode. We need a dyno run of all the different extensions you can put on an impact. I'm talking extension into u-joint into reducer/adapter. BECAUSE SCIENCE!!!

[@PictishPrince]

I always use larger line than 1/2 inch for the 3/4 and 1 inch tools But since I got my Makita 1/2 inch 18V impact I rarely use those larger air tools any more.

[@hammadrehman4257]

These are so scientifically satisfying to watch. I love this channel!

[@Comm0ut]

It would be interesting to drill and tap an adapter for a single set screw to force it in the removal direction relative to the anvil where most power is needed for automotive use. That would eliminate the slop since the gun anvil would be fully CCW inside the adapter.

[@bsowhat]

I used a vintage Husky USA 27203 1/2 to 3/8 reducer on my gen 2 Milwaukee mid torque impact at full power to remove a stuck Allen bolt. Nothing broke. Guess my reducer is a lucky one

[@chipsterb4946]

This was very helpful combined with your 3/8” vs 1/2” anvil comparison. I recently bought my first impact driver and got 3/8” because that’s what most of my sockets are. Two takeaways: 1) overall I made the right choice matching anvil to available sockets, but 2) I probably should replace my 1/2” deep sockets with 3/8” to fit the tool. Any recommendations on big, deep sockets available in 3/8” drive? For example, 17mm, 18mm, and 19mm.

[@user-sg4jm9oq6d]

My advice is pick a brand with a lifetime warranty that doesn't make you pay for a replacement (snap on). Mastercraft/Harbor freight/ Princess auto

[@DownloaderVideo]

Get Tekton

[@musicalmcbride]

The adapters put together at the end of the video is the equivalent of putting extensions together to reach transmission bell housing bolts.

[@boosted2.4_sky]

I would think that they would also lose torque depending on manufacturer...through design and some manufacturers steel might be harder than others... softer metal absorbing torque...

[@zackfishle1009]

I watched several of your videos and I figured now was the time to subscribe and have given thumbs up. Keep up the good work. I feel educated now. . . I was able to break head studs loose on a 4.6 f150 until I needed a wobbly since the gun didn't fit. I bet wobblies loose torque with extra cheese.

[@TorqueTestChannel]

Hey thanks! Yes we have a vid on wobbly adapters. Lots of beans lost

[@randomusermaximuss]

Testing idea; testing your own set up. Specifically how much does it change the results if you over torque the nut/bolt with a high torque impact and then allow a less powerful tool to reattempt the same test. Similar questions on lubricants.

[@brianwilson3133]

What's probably happening when the anvil impacts the adapter and that hits the socket, is the socket recoils which makes the adapter recoil and basically pushes back on the anvil.

[@chubbysumo2230]

as far as the 1 in gun goes, and the 3/4in, since i have both, the trick is that you get the initial couple of hammer hits, but thats usually all it takes. I have a 30 gallon 2 stage triple pump compressor that can keep up with my HVLP gun just fine, but even with a 3/4in air line, it cannot feed a 3/4in and a 1in gun more than a few seconds. I get like 4 good hits, and if it hasn't broken the bolt by then, its loose.

[@cujoedaman]

WTFBBQ is the best industry term for a measurement I've ever seen.

[@retematic2351]

why the fuck did algorithm make me stumble across u in the middle of the week, I'm already an hour past my bedtime and I still wanna keep going. Well, at least I know what I'll do the rest of the week.

[@jeromegrunwald9564]

The last test....I always like doing this when growing up. Go from small to big, back to small. Or visa- versa

[@screwsnutsandbolts]

Excellent video

[@greentjmtl]

If you twist the impact gun handle in the direction you want to move the fastener and take up any slack between the squares (for all sockets/extensions/adapters), does that lessen the torque lose? If it does, might come in handy in situations when your gun is barely unable to move it.

[@tylerlower5140]

We use 1" IR impacts with true 90 psi almost daily at my job 😁 they'll strip threads on 1" bolts if you hammer on them long enough

[@TradeWorks_Construction]

It would be interesting if you guys could take 0.01” stainless or brass shim stock (or whatever size would fit) and place it between the anvil and adapter and between the adapter end to socket just to see if tightening the fit makes reliable gains, potentially enough so to justify doing in a situation where that 15-20% loss is needed.

[@P3D2OH]

Forgive me if this has already been tested or discussed on your channel, but could you test if there are any effects in loosening conical seat lug nuts? I’ve experienced, my buddy as well, Milwaukee stubbies struggling to remove conical lug nuts, on aluminum rims, tightened at 150 ft-lbs. Thanks!

[@colemanbonner]

Always wondered this- my IRC9000 and my PT850 will always break a Honda crank bolt more easily when I have a 1/2F/3/4M adapter and a 3/4” drive 19mm snap-on deep socket on it

[@Jasonitodd]

I have to use adapters all the time, courtesy of GM and their wonderful location for the oil pressure sensor on the LS.

[@cosmoshaven]

I can guarantee that OSHA would find the final test with all the adapters on to be 100% SAFE ;) I laughed at that part and especially when I saw the face shield get put on xD

[@mobilePCreviews]

man it's crazy how many views you guys get. keep up the great work!

[@I_just_change_oil]

I “torque” thing at work at hard to reach to places which sometimes causes me to use a wobble adapter. Torque values are usually between 260 to 500 pound feet. Be cool if you could test torquing a fastener with a wobble impact adapter between the wrench and the socket. Thank you 🤞🏽

[@loktom4068]

After watching this I use an adapter for my job. No problem. Because it's only a low torque application work scenario for me. I will do it again and again if it is possible then waste my time to shop for the recommended size. Buy if you need it for heavy duty application, go get the right one.

[@dougrobertson8658]

I’ve had nothing but bad luck with harbor freight adapters, broke two 1in-3/4 adapters with a 1in D handle Milwaukee. And broken countless others by hand.

[@JT-tz5hp]

The very first adapter test you compared a stubby 3/8inch socket to a deep 1/2inch socket. One is far longer than the other. Maybe you should keep the socket lengths comparable.

[@TheRetarp]

Would have been nice to see cordless vs pneumatic using the same adapters. I suspect the losses would be less with the fewer more powerful impacts per second of air impacts. This had to have been a ton of work already to put together. Perhaps a future video?
