I'm not going to lie.... this made me get the 3/8 all you need is a good step up
Did you notice any temperature difference between them? We notice up to 10% power difference (higher) when they are hot vs room temp.
Do you have any plans to test the flex impact driver?
👍
As always, very thorough review, thanks for all you do
Glad you like them! Thanks for watching.
Great Channel man! I always have these self conscious arguments in my head about which tools are better between each other. Thanks 💪🏼
Great detailed video. I personally would've loved to see a non-welded adaptor so we are comparing with the exact same 1/2" socket across both units. Nonetheless this is great to show the potential of what a 3/8 can provide. Thanks
i think the reason the 3/8 did better than the 1/2 is because the adaptor is welded so it does not lose power like an adaptor would so the added mass of the adaptor actually works like a weighted socket which adds power
The adapter only weighs a few ounces so I doubt it has any effect
@@wendellgreenidge3362 And its longer so it should putout less torque as well.
@DirectCurrent4u but the adapter was used on the 3/8 not the 1/2 and the 3/8 outperformed the 1/2"
If the the adapter causes less torque, what you said isn't logical.
Since its welded, It would be no different than connecting the socket directly to the anvil. Those 4, 5, 6 ounces aren't going to make a difference in the torque.
If the adapter is welded to the socket then it's no longer an adapter it's part of the socket and for it's a super heavy socket which causes more force
I’d scratch my hair if I had any, real puzzler and a great show! Thanx. Tom
Thanks for this! Im going for the 3/8!
I just ordered the M18 Fuel 3/8 drive tonight, and I bought an M12 1/2" Stubby last week.
I was doing the brakes all the way around on my wife's truck last weekend and my M18 1/2" high torque was to long to get on one of the front brake brackets and both the the rear brake bracket bolts so I got the 1/2" M12 stubby.
It removed the lugnuts on my truck (torqued to 130 ft lbs) with no problem....for a 12v, no problem.
I'm really shocked, like you, that the 3/8 outperformed the 1/2".
Someone else commented that the adapter had something to do with it, however, when I watched your side by side between the Milwaukee, the Dewalt and the Snap-on, I remember you saying that the adapter is welded to the socket....therefore the adapter should be out of the equation and not have any influence on the testing because being welded it's now a solid part of the socket. Where with me, I wouldn't weld on my adapter so I can use my socket on either the 1/2" or the 3/8 adapted, so I would have movement between the adapter and the socket.
Love your channel and the reviews.
Just a quick thought...and this isnt to get an argument started. Just an observation and opinion...
Why would you (people in general) want to spend their hard earned dollars on the overrated, underperforming tools of S-O???
Status symbol??? "All my tools are S-O. I've got over $50,000 wrapped up in tools in my $25,000 toolbox."
WHY??? All you're buying is the name. I just don't see it. My dad always told me, a fool and his money soon part.
Once again loving the videos thanks
Torque test channel did a very indepth test of anvil sizes and torque output, even with a custom made socket that weighted a considerable amount it performed worse than the standard socket you'd use with a 3/8" or 1/2", a larger anvil has more mass which requires more kinetic energy to drive it, while 1/2 is not that much larger than 3/8 its still a sizable difference that produces different results.
It's very interesting to see other real world results showing the capabilities of both drives, I've just recently purchased my first impact wrench and its the 2854 and i'm glad to see the 2855 doesn't stomp all over it as for my needs i dont need more than 200ft lbs of breakaway torque.
For hobbyist needs the 3/8 is perfect the compact size makes it handy for tighter spaces, but from every mechanic and tech i've heard from they do still have a 1/2" ready if they need the extra power, with that being said though you can stick a much larger battery on your tool and increase the power output quite considerably.
After viewing this video I purchased the set including 2 5 amp batteries! Downside of watching a lot of youtube, but I really need tools that increase my home DIY capabilities. I will probably order one of the mid torque guns as well in either the 3/8 or 1/2 inch flavors.
Wow! On subcompact platforms no less. Can't figure that 3/8 though.😁 Great video tim!
You and me both! Thanks.
I know it would be expensive but I’d love to see this same exact test done again with two new impacts to see if by chance something was indeed wrong with that 1/2 in or if something was extra with that 3/8 in.
There are multiple types of torque in the tools. I own the mid torque 1/2" 550ftlbs I believe it's rated for. I don't think that this is a good representation of the two. If these are both a low torque wrench then I don't think it matters which size you get. Choose the torque size tool for your needs. Plus, I dont think they even make a high torque 3/8".
Very odd result! I've compared my M18 1/2" And 3/4" Impact wrenches and if using an 3/4 to 1/2" adapter on the bigger gun, it failed to loosen stuff that the 1/2" wrench had no problem with and that's considering the 3/4 version is considerably more powerful.
Then to be more conclusive When used the 3/4 impact with a 3/4" socket, and the 1/2 impact with a 1/3 socket but both for the same size fasteners, the 3/4 impact was much better.
Will be interesting to see what Milwaukee has to say or even if tried another pair of guns to see was there anything different or not right with these two.
Good review and interesting result 😎
Incredibly interesting and informative.
Upgraded from an older 18v kit. czcams.com/users/postUgkxW1vOBRCMrgTCDEijzpVzDWsgI-Jm2iQv I independently chose the drill and impact tool, before I came across the kit.I like the 3 speed impact gun. It seems more powerful than my older one, and it can be set to be really gentle. The drill is more appropriately sized for my use. I used to have a hammer drill, but I did not like that it was so big and it was not a great hammer drill. I rather have a smaller drill like this, and then get a corded hammer drill for the odd case I need that.
There is nothing like Milwaukee impacts. I like dewalt drills and stuff but for impacts Milwaukee is the best no doubt about it. Great vids bro. Can’t wait to get my hands on one of those
Makitas mid torque has 90ftlbs more torque and multiple features none of the milwuakee does.
Stop being a fanboy and buy tools according to your needs not marketing. Btw I own milwuakee super sawzall
@@jonathangarzon2798 On head to heads I've seen the Milwaukee's continuously outperform and outlast the Makitas. Has nothing to do with being a fan boy. The Makitas burned out, the makitas DIDN'T pull higher loads than Milwaukees and the Makitas had the bits slide in the chucks more often. Looks like you might be the fanboy. 1/2 lag bolt trough 4x4's, Makita max torque 348, stops on the second 4x4, Milwaukee 468 drives it flush, drives it so fast it smokes the wood. LOL, Makita's are ok...
I’m a dewalt guy myself, but man Milwaukee’s impacts can’t be beat. Too good
Wow..shocking results…3/8. ..glad I got one…awesome informative video…
Glad you liked it! Thanks for watching.
I just bought that half inch torque Driver…. I don’t get too crazy on the specs and what not but I know that every time I use it under the hood of my car‘s and for any other rusted bolt it has perform Great…. So I am happy with my purchase… but great video it’s always good to see how they perform against each other… thanks..
Added weight, huh... if it were the other way around, people would still claim the adapter is causing the lack of torque. Great video! I’ll still be going with the 3/8”. My high torque can be my only 1/2” for a good while.
You are correct. Not a bad idea going with the 3/8", makes sense when you have the High Torque. Thanks for watching.
Added weight of the socket and adapter = added torque in an impact
The reason why the 3/8" is outperforming the 1/2" is because the adapter in this case is adding weight which helps on each impact. USUALLY, adapters tend to lose torque but if the adapter is made to tight tolerances with very little play, the weight added to each impact can more than make up for it.
I love my M12. Not much it can't handle. Just replaced my entire steering kit using one. Tie rod ends don't come out easy.
In theory, with the same motors using the same gearpack, they should function essentially identically when allowing for unit to unit variance. My personal preference is to use 1/2" anvils for all my impacts.
Went out and bought a 3/8 this week and I saw there's the same thing in 1/2. About capped my pants but after seeing these videos I'm happy with my purchase again
So glad to hear that. Thanks for watching and have a great day.
I own the 3/8 gen 3 compact impact it’s a beast I use it for wheel lugs all the time at work I’m about to buy the m12 right angle impact maybe today
is the right angle m12 worth it because I'm looking to start my tool collection
Went to a shop here in Taiwan (where they do the manufacturing for these tools) and found they had a dizzying number of different models, probably 30 different models just within the impact and standard drivers.
There were about 8 impact drivers all similar in appearance but no idea which one is which one.
The store staff was not familiar with it.
Ended up just buying a cool Milwaukee hammer and leaving it at that.
Models vary between US and international Milwaukee stuff. We have different models.
The adapter adds weight and will increase the hammer force of each impact. Noticed it first time on Detroit Diesel engines main bearing bolts. They are tightened to around like 600 foot pounds it’s a torque to yield bolt so not sure the full torque but the big 1/2 Milwaukee would only break those loose if I used a 1/2 to 3/4 adapter if you used a strait half inch socket it wouldn’t break them loose. But was still super impressed it could break those bolts loose it’s no joke trying to torque them
My problem with the 3/8 is that it’s friction ring only. I would love it more if it was pin detention.
Great video!
Can you make a video comparing the 3/8 with the welded adapter and with a normal adapter that's not welded. Does the welded adapter provide any advatage that will not be experienced under normal circumstances with a regular adapter?
I’d buy the 3/8 for sure. I can use it with swivel 3/8 impact sockets which fits great in tight places. I’d buy 1/2 inch mid torque if i need more power and light weight
Right on, that's the way to do it. Thanks for watching.
What gen is in this video?
I debated back and forth between getting a 1/2” and a 3/8” compact for a few months and ended up getting a 1/2”. I plan on getting almost all the Milwaukee impact wrenches anyway 🤷🏾♂️
They're great impacts, and even this 1/2" compact is a great tool. Thanks for watching.
@@Shoptoolreviews Would be curious if the Gen 2 Mid-Torque ends up the same way in the 3/8 outperforming the 1/2. Maybe the next test?
Thanks Tim
That 3/8 got some power 🔋 & strength 💪. Definitely I will be going for the 3/8 purchase. 😊👍
Good choice! Thanks for watching.
Awesome review! I was not expecting that!
I have the Ridgid Subcompact 3/8" and I was always thinking I should have gotten the 1/2" for the little extra power but now I'm not so sure after this.
Maybe you can test those to see if it will be the same case.
He has tested the Ridgid 3/8 subcompact against DeWalt and this 3/8 Milwaukee in this video it's pretty interesting ...he doesn't have the Ridgid 1/2 inch but you might find this video interesting...
czcams.com/video/-zoNy5s_lhs/video.html
excellent channel ... congratulations ... greetings from Monterrey Mexico ... 👍
Thank you very much!
Open them up and switch the anvils. After that I would say it would be the extra weight of the 3/8” socket and adaptor.
We will probably do this but at another time. Thanks for watching.
I may be wrong, but as near as I can tell, the tools are identical aside from the anvil, anvil washer, and front housing. In order to swap the anvil, you must swap the other two parts and you end up with something identical to the other tool aside from the sticker.
If I had to guess, the reduced weight of the 3/8” anvil allows for more energy to be transferred in the “removal” forces rather than energy wasted in turning the heavier anvil. I imagine this as if you had two Honda civics and one had its interior gutted. The gutted civic is going to perform better due to the lower weight. The crazy thing is how much a half an ounce can change their output.
@@enchantedwenis4994 i wonder if this the same for the m18 fuel mid torque
Maybe one made in China other in Mexico o Taiwan
I got the 3/8 a couple months ago. For working on cars at home, it's great. Nothing has stopped it. Put a good quality 3/8 to 1/2 adapter (NOT HARBOR FREIGHT!!) on it and have at it.
I see many comments talking about the 3/8 to 1/2 adapter...do you find yourself using the adapter often? If so do you wish you would have just got the 1/2 compact m18 impact?
@@user-dy2xu3uv8k It's hard to say, but after using it a while, I think I would go with the 1/2 inch model. Sometimes space is so tight that I figured I didn't want to chance the girth of 1/2 inch drive extensions and swivels. It's so powerful that I don't think a quality adapter causes it to lose much torque.
Check out Torque Test Channel. They have some great testing going on there.
I would be curious your testing difference between the Milwaukee XC5.0 vs HO6.0 as the 5ah uses 18650 cells (20A per cell) while the 6Ah uses the 21700 (25A per cell) which are 25% higher output. Keep up the great work!
Just like a Lisle 19mm Socket for them infamous Honda Crank bolts real world use the 3/8 has a longer heavier socket plus its welded no play to bleed off torque so more mass/power. There's your answer👍 BTW I own both my results all being equal "same size socket" no adapter the 1/2 will take a fastener off faster, once you add adapter to the 3/8 it's the other way around normally anything past 3/8 24mm socket that little bit of mass makes a difference.
Try and find a 1/2 in drive 33mm with about the same mass as that one with the adapter and the results will probably equal out. But the results do seem to say a 3/8 with an adapter could break more then a straight 1/2in drive
You have a heavier socket (and adapter) on the 3/8 drive than the 1/2 inch drive. Surprisingly, It makes a difference.
GREAT GREAT work as expected.
NOW will see what milwakee says 🤔🍿😵🍷🍷🙄
I have the new 1/2 m18 2962-20 and that is nice lug nuts and various other things no problem.
why i didn't find this video before i bought the 1/2 impact 🥺🥺😔🥺🥺
Lol. You're still fine, I'm sure. Both of these are great impacts. Thanks for watching.
I see this a lot with videos using adapters. My theory is the running start. An impact is basically a sideways hammer function. On the 1/2” drive that socket is tight, like putting a hammer on a nail then hitting it. On the 3/8” that adapter adds slop, hold the hammer off the nail then striking it. You can see in the video the 3/8” vibrates a lot more, like it’s getting a running start with every impact. Like getting 2 strikes for the price of 1.
Agreed
Love the mid torque - it's a beast. The impact driver with whatever anvil you want on it does 200 ft lbs. Wish I could have one of everything but I'd rather have an impact wrench with similar specs. I guess if you put a 3/8 anvil it will be even stronger than the 1/2 I've been using:)
Wtf is wrong mine wouldn’t break 120ft lbs lugs. Just got the 3/8th drive and couldn’t brake like half the lugs at work
@@user-white007 dude thats a kick in the teeth
Just bought the milwaukee 1/2 mid torke its a beast now i wabting to buy this 3/8 impact wrench to my milwaukee collection
Great impact wrenches. Thanks for watching.
Im planning to get one of these tmrw new in box for 120$. I’m going with the 3/8 model. Seems like well enough power for what I need and I have a lot more 3/8” sockets than 1/2”.
I'm very underwhelmed by my 2855. Especially considering I paid $220 when I could've gotten the mid torque for $170.
The welded 3/8 socket actually helped the 3/8 add more weight to the fastener. The more weight you apply to a fastener, the easier it is for the impact wrench to break it. 1/2 to 3/8 welded socket and the 1/2 FUEL would have won. However, an adapter that isn't welded (even worse a woble) causes a reduction
Garbage. Your statement breaks the laws of physics. If anything the greater mass of the heavier socket/adapter should have absorbed more energy and therefore produced less torque. What are the physics behind your assertion? There were so many variables involved that it would take a far more detailed test to discover the discrepancies. It is possible that the 3/8 driver had a more powerful battery as not all batteries coming from the factory are identical despite their labelling. It is possible that it was just more powerful because of some difference in the software or hardware, two identical models of cars from the same factory can have different 0-100 times for example.
correct
I've heard this before. More mass added on the socket helps. That adapter definitely helped the 3/8
@@teeanahera8949 not garbage not absorbing energy but creating it. Proven many times. The reason weighted sockets (especially for Honda cranks) exist.
Im sold on the 3/8. Ordered lol
I have a question on Ryobi brand. I started with them 8-10 years ago, whenever they came out with the 20” mower & weed trimmer in the 40v. I have since been using their 18v (One+) tools as well. I have to take apart their battery packs (mainly on the 18v) to repair them when they fall below voltage where the BMS turns off the battery. Anyway, I was wondering if you had a comment on the Ryobi for quality? I do know there are DeWalt battery problems as well as Ryobi (I don’t have any experience with Milwaukee but since the same TTI owner owns most of those I would asssume they use similarly battery technology. Thanks again for your videos. I have seen several of your videos with the same metal plate with those nuts on that metal plate. Good job!
Awesome I made A great purchase!!!!
That's great to hear. Thanks for watching.
Glad I got the 3/8 mid and the 1/2 high. But I would like to see if you can get the batteries to fall off. I hear about this from alot of techs. I am a diy'er and don't use as often as a tech.
We have not had issues with batteries falling off our M18 tools. I know that M12 batteries can break the tabs when used a lot, but not so much the m18. Thanks for watching.
Nice review. I have the Ridgid ones so far so good on doing aircraft mx with them.
I got compact Ridgid ,m12 stubby, M18 and the new makita xwt14 honestly the Ridgid is smallest almost like a right Angle impact and so far haven’t ran into anything Ridgid can’t handle
@@rookiexreviews I have the m12 don’t like it. It was good when I first got it but it only lasted a year. Have been in the shop 2 of 3 times.
The Ridgid impacts are really good impacts with lots of power. Thanks for watching.
@@flyyxmke ya same here I got 5 impact wrenches total and only use my compact 3/8 Ridgid and my new makita 1/2 those 2 get about any work I run into done makita for the tougher bolts and Ridgid handles about 80% the stubby m12 sits in my car by my spare tire incase ever get a flat or some emergency
@@Shoptoolreviews no problem thank you really! for the reviews you definitely helped me decide on what tools to buy especially since Im starting to just work for my Self trying to find my own remodeling/simple mechanic jobs so been buying a LOT!! of tools recently never understood the feeling that I pretty much every tool there is until now lol my girl is not very happy with that part of my new business but even tho rough at times infinitely more satisfying then working for some a.hole supervisor
You should’ve tried it with the same socket. The adapter probably didn’t add much weight. But that bigger one looks like an axle nut socket, they’re heavier than a standard socket.
How about using a 1/2" to 3/4 and see if with the added weight the 1/2 wins with the 3/8 using the same setup
What was the combined mass of the adapter and socket used with the 3/8" drive vs. the mass of just the socket used with the 1/2" drive? If you used a deeper socket on the 1/2" drive to make the differences in mass more equal, I wonder if the results would change.
i know they say heavier sockets are better but ive on multiple occasions raddled on a lug nut with a deep impact socket to no avail then threw on the shallow socket from the same set and right away it undid it
The adapter should decrease torque regardless of adding mass, imo.
Tim, do you know if the 3/8 could achieve the same results loosening 350-500 with a cp 3.0 high output battery?
Harmonics are different using different sockets, thus vibrate differently. I think it has more to do with them being different socket set ups.
This would have been a better comparison if you had the same 1/2 socket that was welded to the 3/8 adapter used on the 1/2 impact. You can clearly see that the socket is much larger in the 3/8 set up compared to the 1/2 socket used in the 1/2 impact. That and the adapter having more mass would give you the 25-30% increase in loosening torque.
Look at the length of the socket on the 3/8 (much longer 16:34)....extra mass made the difference, especially with the socket adapter welded on adding more mass.
Good video
Very interesting video. What tool do you use for torque wrench (cordless)?
So i got the 3/8 version with a 3.0 battery and i just love it. It was a tuff choice over the stubby by im glad i got it. Rated at 250 ft lbs but i swear it has a little more kick than the M12 stubby. It also feels great in my hand. I can get to all kinds of tight places. Yes there might be a tight spot that the subby my fit better but for me its kinda rare and im never afaraid to grab a wrench. Conclusion: I really love the 3/8 M18 AND 3.0 BATTERY. Yes, it struggles with larger tuffer bolts but thats what my 2967 is for.
I wonder if the adapter is giving the 3/8 a little more weight on its impacting action causing it to work the bolt loose
That 3/8 is amazing I use it in automotive work and I able to take off truck subframe bolt with ease I use to have the 1/2 and it didn’t do that it always felt like it lacking power
Great vid brother , I have two 3/8 12v stubbys and there is a slight difference between the tools. We've all seen stranger things happen right ? The important thing here is they are more than enough for their intended use. Your not gonna take off bud or dayton wheels with these however I'm certain they will take care of what you need to do. Personally , if you are using a compact impact wrench you should only need 3/8 drive however with these numbers a 1/2" just might be viable. I have no experience with these two wrenches because I went straight to the mid torque , if you use the settings on the tool along with the variable speed trigger the only difference is the mid torque is a little bigger but by sucking up that sacrifice you can do a whole lot more with said tool.
You made the right choice with the Mid-Torque. That's just a great all-around impact wrench. It does just about anything you need, if you're working on light trucks and cars. We agree, they do more than enough, and that's why we weren't concerned about the 1/2" not doing more, it's already outperforming what it's supposed to. Thanks for watching.
I have the 3/8 compact and the 1/2 high torque 2767...I barely even use the 1/2 anymore...3/8 does pretty much everything I need
After buying the 3/8 stubby and 1/2 mid torque, I'm a little distraught right now. Breaking hearts out here lol.
What do you mean? Isn't the 1/2 mid torque a lot more powerful, but the stubby I'd lighter? What's the issue that you're distraught?
Real interesting results. Wonder if that particular 3/8" impact is an anomaly or if all will perform like that.
Really not sure, but even the 1/2" performance level is pretty awesome for the compact. Thanks for watching.
sometimes the sockets matter, for instance i was trying to take out a bolt using a matco mid-length impact socket, the bolt would not budge, switched to a snap on deep impact socket on the same gun, took it off the bolt in 6 seconds. The snap on impact socket had a much thicker side wall. maybe the difference in socket affected the results?
u switched out the battery, but kept the same socket.
I would like to see the 3/8" drive Milwaukee M12 impact vs this 3/8" M18. I've seen many people who have both claim the M12 is just as strong as the M18.
Now I want to see the 3/8 vs 1/2 mid torque.
Genial!!! Ahora voy ppr Llave de impacto 2854-20 de 3/8.. las pruebas demostraron
su capacidad de fuerza aunque con características similares
Ya tienes la demostración de la llave de impacto de 2962P-20 ????
I believe it has to do with rotations per minute. The 3/8 anvil rotates more per minute than the 1/2, I’m Just guessing I could be wrong. That’s the only reason I can think of.
Great channel! I know they're supposed to be identical but my armchair hypothesis is that the 3/8 can "spool" up faster so to speak. Regardless, I'll be looking forward to what Milwaukee says.
The reason is because you solder a 3/8 adapter to 1/2 socket, it's make more mass. Heavier your sockets more power you get.
I'm pretty sure he didn't solder it
Yes he did weld the adapter to the socket.czcams.com/video/-zoNy5s_lhs/video.html
@@nexus5482 he is meaning that he welded it, not soldered it.
2855 is a lemon! By any chance, is there a theoretical number or range of numbers should we fasten a m14 x 1.5 lug nuts for 2 full seconds? I was wondering if I can get to the 100 ft/lbs mark in 2 full seconds run. Thanks for the great content.
I think the 1/2 inch isnt broken in yet vs the well seasond 3/8 impact after you put some miles on the 1/2" I think we should revisit this review 😉? I own these tools and have a question is there a break in period for the motors planetary gears anvils and so forth so my question from out the box is there a period of break in I will contact milwaukee and ask these questions unless you already have the answers please get back with me on this thanks brother have a wonderful day
Can you try this test with the 3/8 and 1/2 mid torque wrench’s?
Yes!
NEEDS another 3/8 QUICK
Difference is most likely in the socket. The socket used in the 3/8 is heavier which equals more moving mass.
What sort of adapter is it? Not concerned about it from a power perspective just curious of it’s purpose. Is it just a wobble adapter for convenience ?
It's got to be the mass of the half inch adapter on the 3/8 impact wrench that is making the difference plus the weight of the weld
I guess I need to run 1/2” adapters for more power.
@@runningproblem Adapters will lose more power than you gain from weight / surface contact
@@kvernesdotten not when it’s welded it makes it one sold piece
@@oakleyjohnson6792 Check torque test channel, they proved it doesnt matter. Its not the number of connection points that cause the most loss, its the distance of material the force have to travel through (from anvil to work piece). 3x5" extensions have the same loss as 1x15"
I've watched multiple videos of exactly that. The additional weight makes more impact power. Watched one, that had a really heavy weight added and made a huge diff.
How high can the grey torque impact with the arm go? use one that we have to tow a compressor around id like to look it up save alot of Hassel if we could just get a few batterys instead of towing
What sockets do you recommend? Thanks!
I say go with the size that best matches the drive size of sockets you use so you’re not adding length with an adapter.
I believe the difference in performance between these two are just normal manufacturing variation.
Bought the 2854 and 2962
Can you please do the same video but with the Milwaukee 3/8 and 1/2 mid torque impacts? I understand there's a 50 ft-lbs out put difference but I'm very curious about the results.
I don't believe that we have both mid-torque models, but we can check. Thanks for watching.
Thank you for the response. It would be awesome if you do have both models. I'm sure there are plenty of us that are curious about the results.
I'm just curious if 3/8 could lose bolts if adapter would not be welded
Usually to say: The lighter weight of the socket, the more powerful of impact torque. But also affected by the quality of battery, contact tabs, driving circuit, quality of motors
I have both of these and I never use them because they are just to weak. Go with the mid range. like the 2962 It Works!!!
kinetic energy = 0.5 × mass × speed
The kinetic energy of the 3/8” is clearly higher than the 1/2”.
You could verify that if you wish ( probably not worth dismantling either to weigh the anvils for this rough calculation.
Weigh the 1/2” socket & the combined 3/8” adapter and socket.
A hand held rev counter would give you rpm which would then be converted in velocity.
The above formula then provides their kinetic energy.
It has to be the socket/adapter weight difference as opposed to any difference in rpm/velocity.
Enquiring minds need to know (for sure.)
I would like to see the test without the 1/2 adapter to 3/8 or put an extension on the 1/2 to be the same. Most of the time if you just need a little more power you can add an adapter to help the impact loosen a nut. It helps the impact break the nuts free with that little extra space between the socket and the impact.
What would happen if you welded an extension on the 1/2" socket. Like a inch long extension
Are these compact wrenches worth buying if you have the Mid-Torque 2962 1/2 Impact Wrench? All I see is it's 1 inch less in length and 1 pound less in weight. I don't think it really is.
Just a thought, I could be wrong, but could the extra slip in the 3/8 be providing more momentum per impact? Since there’s more slop there more room for momentum to be built upon anvil strike, momentum increasing the energy output on the nut?
Adapter was welded on for the 3/8
Does the adapter and socket fit differently?if one has more slop might change the outcome of the tes
Thanks for watching.
