This Screwdeiver is for Electrical installation work. When you are installing thousands of breakers per year. You screw in the contact in electricly and then apply the correct torque with one of those Slip-Clutches by Hand. It's a very specific Tool for a very specific industry, nothing for regular electronics/repair work.

The extension is a torque indicator. It will click and the yellow ring and red adapter will rotate in opposite directions when the torque value by hand in reached. Torque extensions up to 7.0 Nm are available.

Send it to AvE, we need a proper BOLTR! :D

Apart from the an wobble, this really is a thing of beauty. To answer your question no your not using it right. The torque adapter is to stop over tightening of terminals as this causes the copper wire to creep which ends up loosening the terminals.

The problem is you weren't applying 2.8nm. It would be difficult to apply that much torque to a phillips head without it slipping or stripping. Try a flat head or torx. All of the things you're complaining about were most likely specifically engineered that way. The wobble, the torque slip, the motor cut out, all designed for a specific application. The wobble is likely built in so the handle has some compliance when its turning, to stop the screwdriver from producing a force on your hand if you're not exactly concentric with the screw. This is obviously built into the design considering the rubber oring that holds the bit it. I could be wrong though.

RTFM "Just imagine: a screwdriver which allows you to work twice as fast. An electric screw-driving assistant which relieves you of bothersome screw-fastening, yet allows you to finish tightening carefully by hand. Too good to be true? Not at all. The first e-screwdriver from Wiha An electric screwing assistant which relieves professionals of bothersome screw-fastening, yet allows them to finish tightening carefully by hand. Ideal for thread screws and delicate screw fastening tasks. No question about it: speedE® is a true revolution for anyone who works with a screwdriver. With speedE®, you are faster, healthier and more efficient while out on jobs.”

Maybe the wobble is a feature? For example, with the wobble you can have some misalignment and still don't detach the tool from the screw while spinning

I'm still wondering why you didn't take it apart. ;)

Just to underline the function of the easytorque - it's not related to the electric function at all, it was already a product in the slimvario product line, and is meant to torque limit a normal hand operated exchangeable-bit screwdriver. I'm not excluding the possibly that the unit you got was broken, but bear in mind that 2.8Nm is quite a lot of torque on such a small screw, even though you have quite a solid grip on that handle.

The torque adapter is used when you are manually tightening a screw. When you tighten the screw to the preset limit shown on the torque adapter the bit will just stop turning further even if you keep turning the handle. The torque adapters are available in different "strengths". Probably not too useful for a homeowner but for a pro it will prevent over-tightening and stripping.

That torque extension is for tightening screws on industrial equipment, like relays, switches and so, where that 2,8Nm is around the required torque to tighten the contact screws.

I do not understand the easy torque adapter. But in my minds eye.... This tool is not meant to break free or tighten screws. It is more meant to greatly reduce multiple screw removal/replacement without a lot of wrist twisting. Once the screw is free it will spin it out for you right quick. Upon reassembly the driver will spin it in quickly, stop at a light torque then allow you to snug the screw proper by feel. I do not think it was meant as a regular tighten and loosen driver, more just to keep from doing a lot of cranking when doing a lot of screw fasteners.

The adapter will "klick" at 2.8Nm like a normal torque wrench. The torque is at a fix value. You can buy different values from wiha. Maybe your adapter is faulty?

What about that yellow part of that adapter? Does it rotate? Maybe it has inside slip ratchet?

Stay tuned for Pt 3, the discovery of the turning part with a marker on it :D

This screwdriver is designed for the electrician. Usualy, the miniture circuit breaker you can have at home must be torque at about 2n.m; no more ! so this screwdriver is perfect if you have to tighten a lot of this circuit breaker.

Dave, 1 question. Why are you using an electrician's installation screw driver for tightening a screw on a case? This tool is obviously not intended for the application you are using it for, and its main feature (even somewhat clearly pointed out in your other video (the recommended by doctors part in the marketing blurb)) is that one doesn't need to twist one's wrist/arm repeatedly to screw in a screw. This all results in a lower risk for repetitive strain injuries. Main market being electricians. (And likely not the industrial kind either, since they usually likes to use Wago terminal blocks and such, screws are falling out of favor in the industrial scene. While the consumer scene uses screws, but mainly uses more and more breakers/sockets/switches and other similar things in their electrical installations.)

Like Butze already said- its specifically for electrical installation works. Unlike in US domestic panels, in EU we have to torque each and every breaker with the correct setting (where screws are still used). Such tools enable you to quickly drive in the screws and you just torque the last turn.

I don’t see a problem in this product on metal screws and not wood screw. It is conceived based on time management for professional maintenance and repairs. You see, it takes a fraction of a second to break loose a bolt in electronic equipment but it will take N times longer to disengage the threads, manually. The powered drive was intended to reduce N down to a small fraction of N and were meant for speed but force. Likewise in manual fastening cycle, N times longer to the last thread only takes a split second to snug it. This tool speed that up. Snugging but stripping the threads (or bending drive tip) is another critical consideration. When working with self tap screws I will not give up the opportunity from receiving torque/force feedback in manual operation at the last moment of quarter turn. Because I need to assure that plastic thread ( or bit tip) will not be blindly stripped down, as it will otherwise be by the motor drive to an unknown torque setting. Those who confused or complaining about this product spend most of their time toying with professional tools but professionals themselves.

"It's electric" If you've ever been to a wedding in the US, you probably instantly thought "boogie oogie oogie oogie"

I've tried to find an user manual for this thing for 5 minutes and failed ... but to my understanding the easytorque should slip at the rated torque. maybe you need some pliers to test it.

Nice one Dave. Love a good follow up.

Thank you for being so honest with your reviews. You’re the only you tuber that can receive stuff to review and still be brutally honest.

Check into the dewalt 8v max gyroscopic screwdriver. It's got plenty more features, torque and is nicely compact. A lot of people in HVAC field use this for service work.

Just because you don’t understand something, doesn’t make it bad. I am an electrician, I am not a fan of wiha, all the wiha stuff I have previously owned wasn’t great for the price. But I like the idea of this driver. I am happy to torque stuff up by feel but love the idea of a compact driver to take all the slack up on a screw especially when there are dozens of repetitive screws to do

Still doesn't explain the exorbitant asking price lol

The torque adapter is supposed to click when it reaches its torque limit. Maybe yours is busted.

Don`t understand the torque adapter well BS 7671 requires all terminations to be tightened to the correct manufactures torque. This information is available on line. Look at set 3 over £543 and all the different torque adapters come with it. So all your termination can be to manufacturers spec. BS 7671 is harmonised across Europe. So this (LAW) applies across Europe and means nothing anywhere else in the known universe. I hope that clears that up

isn't that extra piece supposed to be there, so you can put in regular drill bits into it? like if you want to unscrew weird triangle screws, you can easily find bits for it, but not a full wiha thing

Love my Wiha tools but as currently configured this one won't be joining the family on my workbench...more design work needed unfortunately. :(

If they can do 1 electronic torque setting they can do more, probably just monitors motor current, calibrate that from the known mechanical setup, seems pretty simple with a couple of components easily. I don't know how they would get multiple speed settings in there mechanically though, the formfactor probably wouldn't allow it.

"A click signal can be heard and the yellow ring and red adapter seen rotating in opposite directions when the torque is reached"

According to the website the adapter is used to select different torque settings as you can pick a bunch of different ones. Probably some inductive pickup or something.. Price of this thing is ridongculous though.

That adapter is more than likely for generic hex bits for special tips but still provided the 1000v insulation. Maybe try it out with some standard hex screwdriver bits?

What’s the max torque on a #1 Philip’s? Whoever, just because it’s wigs doesn’t make it worth it. Was it made in Germany of Taiwan? They have plants in both countries.

The snobdriver!

There is demonstration on KZfaq: "Tutorial: Wiha easyTorque electric torque Adapter" It's starts slipping.

OMG I HAD NO IDEA A TOOL LIKE THIS EXIST. I have always joked with my coworkers wishing for a normal sized screwdriver that spun it self... and HERE IT IS!! Wtff

As a few have said, it could be defective but, the adapter looks like a torque limiter. Does that yellow end ring rotate in with respect to the arrow on the main body to adjust torque?

Is the wobble as the insulated bits are 6mm across flats, but the handle also accepts 6.35mm bits (non-insulated) ?

your torque adapter seems to be broken - it's clearly described on their website, that this thing is a tool to provide the exact torque (according to ISO 6789 :) to a screw, making "click sounds" when reached...

As someone who wires control panels for a living I can see a legitimate use for it but with a price starting at 299 forget it.

I expect it uses either the motor current sensing or battery overcurrent protection for the "electronic clutch".

The torque adaptor is most likely an encyclical gear box, try holding the yellow end and running the screwdriver, if the bit turns slower than the motor end you know it's a gear system torque multiplier.

You apply the rest of the torque by hand. The adaptor is a limiter.

Surely the torque adapter is meant to work like a torque multiplier, where the input turns a multiple of times more than the output.

There is a second edition of this screwdriver - faster RPM, better light, and two torque settings!

An automatic screwdriver for when you don't want to worry about torque. It drives the screw in than stops to let you hand tighten.

Need to test this turning against a torque wrench or a weighted arm to check if it actually pulls 0.4Nm on motor and clicks on 2.5Nm . Otherwise you may accidentally destroy screw terminals on your μCurrent when trying to torque them all to spec.

Why is this screwdriver so ridiculously expensive??? I bought the Hammerhead electric screwdriver for a little over 20 bucks and its great!

is the adapter for the 1000v isolation? at 1:41 you can see it says 1000V on it.

I almost think that once it snugs down with the little motor, you grab the "E-Z Torque" and turn it hard like a screwdriver.

Just to follow up on my comment on the original video regarding the wobble - that's terrible! I really thought it was going to be better with the adapter.

Dave, sounds like you want the Bosch go screwdriver. It’s only $40 usd, has more torque, variable speed and torque settings. However, it’s not v rated.

I got a nice little $8 US electric screwdriver that uses replaceable AA batteries. Works way better and has lots more torque. When I find myself out of juice, I just pop in more batteries and "Bob's your uncle" away I go.

Maybe the adaptor is to allow the use of driver bits that are all metal. That way, the voltage rating is maintained at the handle

how should a torque Converter work without any additional fix-point, newtons law forbids that

"The easyTorque adapter provides controlled screw tightening combined with safe work practices for electric applications. This torque adapter guarantees process-safe use, thus safeguarding against material damage and eliminating the need for refinishing. Compatible with all slimVario products, the insulated easyTorque adapter also ensures a secure hold for 75 mm slimBits. The handy adapter thus transforms the slimVario screwdriver with bit holder, the slimVario Stubby electric and the LiftUp electric screwdriver with bit magazine into a torque tool in next to no time. A click signal can be heard and the yellow ring and red adapter seen rotating in opposite directions when the torque is reached. With a release accuracy of +/- 10%, the torque tool complies with EN ISO 6789 requirements. The easyTorque adapter undergoes an individual piece test as per the international IEC 60900 standard, allowing users to work safely on live parts up to 1,000 V AC." So, it seems to be a torque wrench like thingy...

If you gotta do hundreds of screws, get a smaller powered drill. That one you can set the torque on, and it is easier to hold and stuff.

Must be broken. I can't understand it otherwise. Maybe it is to give 1000V CAT III rating? what CAT rating is on a main screwdriver body?

Nothing worse than when your wobble gets worse!

Try a review of the DEVON 5612-Li-4 screwdriver.. It seems like one of these but it's just a screwdriver, non-torque.

Is there a planetary gear in the adapter? With less turns / minute you get more torque.

I like the extension. Would be nice in my makita driver.

So. Did you charge the batteries yet?

Aren't you suppose to turn the yellow part to set the torque ?

I already had the same thought after seeing the first video but sadly using the extension bit aka torq adapter didn't pan out as helpful at all

It's not an adapter. It only is a slip clutch to limit the torque when you tighten the screws by hand to the torque it's rated for.

It’s for saving me carpal tunnel when it’s energized. I torque with a larger screwdriver.

The tool needs further development, right now it is like an answer searching for a question.

Maybe try regular bits in adapter.

I checked some videos on youtube, it is a torque adapter. It looks like yours is broken.

The 4nm adapter is for your when you're finishing the last tightening half-turn of a screw by hand; it will make sure you are at about 4nm, just like any torque wrench minus extra settings because it's compact. Still overpriced.

Dave, I don't think it is made for what you are doing with it.

You are not using this tool correctly. It is designed to insert screws without a chance of stripping the threads. The final tightening is intended to be done by hand or using a properly calibrated torque tool if necessary. Right tool for the job, etc.

Did you charge this thing up? I use a similar one of these at work and the torque correlates strongly with battery charge

You should use the es121. It works better looks better and has a open Source software

Meant for electrical installation work, not for general work.

Err Dave, you did screw that screw in easier with it, than twisting your hand, and you were able to apply the amount of tightening force YOU wanted and YOU FELT. Did the wobble stop or impede the operation/result? Didn't look like it. On the instruction sheet doesn't it say "FIX WITH FEELING", ie tighten with feeling. With benchtop repairs, each set of screws/bolts have their own tightness FEEL, I don't use a torque screwdriver to TIGHTEN screws when I refit EVERY screw. The last thing I would want to do is keep adjusting MAX torque each time I change application. The fact that the shaft has some wobble didn't stop you accomplishing the task. This is one product that I would love to have. If you don't want it mate, I'll send you my postal address. I know you are doing a critique of the product, but how much do you want from a screwdriver and how much will you pay? Seeing as we have no Automotive Assembly lines now, there must be some of the production line tools going cheap, including intelligent power screwdrivers. Tom...

SpeedE V2 will have additional settings. This is only the beginning

If the adapter had a planetary gear set in it where the blade moved at a slower rpm than the handle - doesn't look like it - it would multiply torque. Unless that yellow ring does something it just looks like an extension.

so you cant make your 200$ electric screw driver sense high and low torque ...and it is pretty slow? .... okay, cool - ill come back if these things are actually good. do they make torque-slip adapters for standard electric drills?

There is a gear reduction in the adapter. At 3:14 you clearly see the adapter spin faster then the screwbit. This will increase the torque at the end seen from the motor.

you can wack in anything dave, anything

This is the purpose of this type of driver - www.hager.co.uk/downloads-services/technical-services/torque-settings/52986.htm Also the things i'ts mainly designed for use PZ not Philips heads. I've also seen meter tails into a SB switch disconnecter come lose over time after not being tightened enough!

The only thing you were right in assuming is that you don't understand. Everything else is understandable from a professionals point of view. Since you only have the 2.8 EasyTorque adapter, you weren't able to put enough pressure on to see it working. Try a lower torque and you will see what I mean. Get a EasyTorque adapter with a lower torque and you will here a click when the right torque is set.

I think you were right when you called it an extender, that thing won't do anything to increase the torque.

You don't have the torque adapter installed properly. It has settings and you have it set on 1 to 1

That would not replace my 2.4v Milwaukee cordless screwdriver.

Take it apart!

That holder is probably just a standard bit holder for your normal 1/4 screwdriver bits. That’s all

Wiha the best electric tools in world 👏👏👏

I bought this exact some kit and it's crap, mine was exactly the same as this one in the video and absolutely no back up or support from WIHA Australia and nearly $600 Au

Purchasing or the marketing departments attempt at producing something.. This whole thing just doesn't make sense. If anything, it looks more cludgy and pointless than just using a regular screwy.

looking at the wiha website and the video i've linked below, the torque adapter spins at the specified force to stop you over tightening screws. I don't think its supposed to work in electric mode, if you manually try to over tighten a screw it should start spinning when you hit 2.5Nm. kzfaq.info/get/bejne/fqqUrM5hxr2dcqM.html

This is not a review, is a demonstration of how not to use an electric screwdriver; however, for your info, this is especially designed to help turn the screw ONLY when it is loose, and use the hand to turn to appropriate torque with the adapters. That's it, easy. But pleases, next time learn before starting the camera.

Is AUD$490+ reasonable for an electric screwdriver?

Man, it was free - be grateful and stop complaining .... send it back then!

Yeah.......nooo.

I did put this screwdriver through few months of heavy use and it stucked two weeks ago. Its interesting concept but in current form its just overpriced toy.
