Not a heap of info out there on these, but being Wiha, they should be decent. It certainly has the best lighting system I have seen on these types or drivers, being a full ring light rather than the usual single or dual led.

Only ratings I could easily find are on Amazon, which gives 4.3 stars out of 65 reviews. Just click on the ''translate'' button to read them in english. There is also a better description as well. https://www.amazon.com.au/Wiha-Cordless-Screwdriver-Magnetic…

A fair few available but scattered. https://nrby.in/bunnings/0414566

    Thanks.. my bosch is still going strong.. will skip

    • garage sale on 09/11/2023 - 14:09

      i have the bosch but being able to set 3nm and 5nm makes it ideal for working on my bike.
      thks, grabbed one.

    I saw them in store yesterday. They're very low power, I suspect only appropriate for things like electronics.

    I've got the supercheap 12v stuff for low power needs and the impact driver is good for basic jobs, screwing into chipboard or soft wood, or things that have been pre-drilled. But my low power 12v stuff still has 40nm of torque, this only has 5, which doesn't seem like enough.

      I have a black and decker 4v gyro screwdriver and it has a surprising amount of torque. It only has 4nm apparently.

      • stratbargain on 09/11/2023 - 15:38

        Agreed, they are surprisingly beefy for what they are. And the Gyro is a really smart way to control it. I'm surprised it never really took off

      5Nm is perfect for a cordless screwdriver. (and this deal looks great - I grabbed one)

      Ideal usage for a cordless screwdriver is stuff like assembling furniture, disassembling things etc.

      For the same task an impact driver is high RPM and torque, so it is easy to strip threads. You can use a drill driver with the clutch to limit torque, in my experience they are heavy and bulky compared to a cordless screwdriver.

      It's certainly not a tool that everyone needs, but I get a lot of use out of the now pretty old Ozito model I have. That only has 3.6 Nm of torque and it happily drives screws into most wood without pre drilling.

      More Bunnings website weirdness. Can via this link below, just scroll down

      Bunnings seems to do that a lot lately because of OzBargain traffic.

      General PSA:

      For Bunnings links that don't work,. instead search the product name on the Bunnings site (or the I/N: 0414566 in this case) and open it from the results.

      If that does not work, you can also add it to cart directly from the results.

        Yes, have seen it a lot lately and every time I have posted a deal recently its happened. Next time I will add t your method in the original post as well. Thanks fro the info, cheers.

  • bboz on 09/11/2023 - 11:51

    Thanks OP, got.

  • ESEMCE on 09/11/2023 - 11:58

    According to one of those Amazon comments, this does not have variable speed.
    That makes it as useless as the Bosch and Worx electric screwdrivers IMHO.
    It'll cam out when trying to do anything remotely difficult and you'll end up just using a manual screwdriver while being annoyed.

    • Prong on 09/11/2023 - 12:32

      Fully variable speed as in like a drill trigger?

      That's not very common on electric screwdrivers. But the electronic torque limiting used here is functionally the same - just it has three fixed "speeds" rather than a variable trigger. It will use PWM to limit the motor power (like a drill trigger does) so lower torque settings will be lower RPM under load.

      IMO some sort of torque limiting is super important on a cordless screwdriver. I suspect having three settings is easier for most people to avoid stripping screws, compared to using a trigger to control torque. Having a little variable dial would be ok too.

      Some screwdrivers just use a clutch, which gives full RPM up to the torque limit, and can be good or bad depending on specific task. It does add a bit of bulk though.

      • ESEMCE on 09/11/2023 - 13:17

        Yes variable speed like a drill.
        Unless you're screwing into an already threaded hole (ie reassembling a previously assembled piece), you need the control of variable speed to allow the screw to bite in straight for the first few mm, after which you can add on torque and speed.

        Is the Torque limiting automatic or selectable? Even if it is manually selectable, I'd argue it is still not functionally the same.

        Avoiding stripping heads should largely already be covered by the low max torque output.

          Manually selectable. And 5 Nm is more than you'd think, and will easily strip screws.

          And yes, a variable trigger speed control screwdriver does not have the same functionality as one with multiple torque settings. That was my point - I was just explaining how it worked, and thus the crossover.

          It's the method used to provide electronic torque control that functionally the same as the method used to provide variable speed control with a trigger. PWM (Pulse Width Modulation) to limit motor power. The difference being the variable trigger, versus the three settings. For example, many drill speed controllers use a trigger that isn't infinitely variable - it has a sliding contact that work like little switches to give 10+ speed settings as you pull the trigger.

          Based on that, the resulting functionality of the screwdriver is quite different. That's why I mentioned the lower torque settings result in lower RPM under load.

          For your sort of usage, the lowest 1 Nm toque setting won't be be 5x slower than the 5 Nm setting. The low load speed will be very similar and it will only be slower when driving a screw that has some resistance. With no lower power setting, you can't do very slow operation with no load.

          In these sort of cases, I find the easiest approach is to hold the screw and driver tip with your fingers. Not only does it aid the screw going in straight, but your grip provides the extra load needed to drop the RPM. At 1 Nm, you can easily vary the speed as needed by squeezing a bit harder. The same trick is useful when using many drills, as the ultra low speed control is not very good without load.

          The other handy option is to provide the PWM yourself by pulsing the trigger switch. It's easier to do on some tools compared to others, as ideally you need to find the point where the contacts in the trigger just touch, and then jiggle the trigger small directions each way. The less you have to move your fingers, the finer and faster you can pulse it, and the better control it gives.

          For anyone who needs variable speed trigger control on a cordless screwdriver, something like the Bosch IXO offers it. It's $79, not $29 though.

        • Prong on 10/11/2023 - 17:05

          Mine arrived and I was wrong about the torque limiting method. It cuts power once a certain load is reached. Probably by monitoring current draw.

          Which IMO is a less flexible option as you can't add manual torque control by hand. The trigger is also not great for manual PWM!

          So definitely not suited for usage where speed control is helpful.

    Tempting but I already have a Bosch IXO and a Vessel 220 P1. This one does have USB-C charging though which the IXO does not… And different torque settings hmmmm

    • garage sale on 09/11/2023 - 14:11

      the USB-C and torque setting is what sold me, have other drivers for heavier work.

    I saw this and got excited at price and WIHA but… thought do I really need this? I got a full 18V Makita set I barely use. Battery doesn't look replaceable so will likely have only used a few times before the battery gives out.
