Customer Reviews for Milwaukee M4 4V Lithium-Ion Cordless 1/4 in. Hex Screwdriver 2-Battery Kit

I’m an HVAC contractor and use this tool constantly, and have purchased them for all my techs, as the majority of the time the M12 and -18 impact guns are way too much torque than necessary; unfortunately, mine suffered the common switch failure and won’t work at all anymore. I’ll take it back to the distributor for warranty but not having it only reminds me how much I rely on it every day, and why we professionals pay premiums for our tools. Hopefully the new one has an upgraded switch by now, great tool otherwise 🤷🏽‍♂️

This is a great tool. Replaced my older model, after 10 years. looking for another 10 years for this one.

This is an absolute must have if you remove control boards and such. Just Awesome!!

Its built very well so it can take a bit of a beating. I like that its a 2 speed and has the tourqe control. Apart from wishing it came with two batteries i have no complaints. Its a great handy tool to have. I do recommend it.

Saw This Used On Youtube by a guy who builds computers and he was showing it was precise enough to install Motherboard screws and other computer components. So I had to have it, and yes it does work excellent for building computers and not screwing up the screws or components, I usually set it on 2 strength. I used 12" and 8" #2 Phillips bits with it.

I am left handed and really need it to be useful in that hand, I really wish Milwaukee would think of others. I could have just gotten a Black and Decker if I just wanted something basic and it would have been a lot cheeper. Also if you use it as a straight screwdriver it is extremly long because of the battery/handdle Very unhappy i am returning it and getting something else

I had the Nicad version of this screwdriver when I was working and I used it a lot. It fits great in my ruller pocket. This one is even better. I use it for things like installing outlets and switches. It also works great for hanging pictures. I have plaster and lath walls, so putting in screws isn't easy. But this screwdriver does the job. But is didn't do so well driving #8 x 2" drywall screws when I was hanging a grab bar.

Awsome tool. I still have my original. I upgraded to this one and it exceeds my expectations. The power seems to be double the original. It can handle large screws. Its not a replacement for a full size drill. It will speed up your work and save your wrist.

Great driver,Tons of tork for 4 volts, the battery lasts a long time, I have been using it off and on for a month and I'm just now down to three lights on the indicator,the clutch ratchets in reverse which is good and cuts the motor off forward. I expect to be using this for a long time to come.

We wanted a battery operated screwdriver that was light, easy to use, ergonomic and durable. Most are not durable and we have bought many different models; for most battery screwdrivers, the forward/reverse switch is the first thing to go, in an industrial setting. We chase threads with a modified tap, so, forward and reverse many, many times is what we put this thing through and so far it is up to the task. Time will tell if it will hold up; I will update this if it starts to fail.

Perfect size and torque settings . Great tool

Really handy tool, works great, saved me a lot of screwing with my own hand.

Kind of expensive but Milwaukee quality. Caught on sale helped make the decision to purchase. I have had cheaper versions that failed since batteries not replaceable.

This screw driver is great but it clutches out to quickly but the batteries do last a long time all round it's a good tool

good little tool. works great on rc cars.

I like it. The only thing is that it’s for little projects, it’s not that powerful

Amazing product. I love the levels of torque power you can get from it.
