Kawasaki 841426 1/2-Inch Impact 7.5-Amp Wrench

I use this to pull apart old Mopar engines and cars. If a bolt is astronomically stuck, it will not remove it. That is the job for a large breaker bar with a pipe hooked to it or I warm it with a torch first and hit with some spray then the kaw impact. Now for any normal nut or bolt, its off in a flash.I would bet this is not as strong as a high end air impact but it is way more fun because it is quiet and very portable (just an extension cord reaches me 150 feet from my shop). I must also say that it is longer than an air impact so fit in tight spot where rear space is key, obviously wont work.Long story short, it is made solid, quiet, portable and works on lugnuts, frame bolts, engine head bolts and obviously smaller bolts.

I bought this to help with the tires and stabilizer jacks on my camper trailer. It worked just fine, of course it doesn't have the torque an air driven model would have for the job. But, I don't need all that torque. If you are going to use it to change tires , I would suggest unbolting them first, lubricate the lugs and nuts and bolt them back on using the Kawasaki wrench. This will solve problems the wrench has initially busting loose those nuts that were over torqued by a third party mechanic. You'll thank yourself when an emergency happens. After all the hardware is re-torqued to adequate foot-lbs by the Kawasaki, your good to go.There are two(2) minor problems, which is why I gave it four(4) stars instead of five(5). This wrench is a bit heavy, making it a little cumbersome to handle for a prolonged period. The second has to do with the carrying case. The inside of the case is made with a packaging gauge plastic that cracked easily from the vibration from it's traveling for delivery. The accessory sockets had fallen behind the broken plastic. I had to shake the case to get the out.If you need an inexpensive impact wrench that has descent quality, I think anyone who purchases the Kawasaki half-inch impact wrench most likely won't be disappointed.

I was concerned that an electric impact wrench might not deliver the torque needed for replacing motor mounts. I didn't need to worry.Someone posted a poor review saying this was too heavy. That's because it's a well-made, heavy duty tool, with a large METAL gear box on the front end.It made the job of replacing three engine mounts on my wife's car simple and quick. It has plenty of torque (power) and spun the old nuts & bolts off quickly...and spun the new ones on. I didn't bust one knuckle, and was done in less than two hours. I wish I'd bought this years ago!

So far I have used this for light duty work and it's doing great.Update 27 May 2015This wrench, I'm not sure if it lost its impact power but it cant open up tight nuts or bolts. Its also extremely loud that it made my ears ring for months after its first use. I think I will give it away with ear plugs to some lucky soul.

I use it mostly for tire changes and break jobs and some construction applications. It does the job. Not bad for the price.

I love this thing, it has great torque for what I use it for. I have had to use a air impact instead on a few things, but that's to be expected there is no way these electrics can compare to air for real torque. BUT not having to start up my air compressor is awesome! I work out of my truck so I have a AC converter that I use and now on most jobs I don't even have to start it for hanging gates, which is the main reason I got this thing. But of course I use it for other actual car and bike work, and it works great so far.I have noticed that there is a grinding coming from it, but so far it has not effected/affected?? the tool. Still works.This does not get used everyday, just maybe 1 time a week. So for a mechanic I'd say stick to air, but for the hobby guy, get it.

The best thing I can say about this is that it sorta works. It'll take lug nuts off no problem and probably the occasional rusted bolt but don't expect it to be your end all cure. The biggest problem that I have with this wrench is that it's huge and heavy, but not the type that inspires confidence. Out of the box, which was broken by the way, I pulled it out and thought is this going to fit where I needed it to...nope...and this wasn't a tight spot either. I needed it to take a couple bolts off that held the caliper bracket on in the wheel well that were pretty tight and rusted a bit, my car is a 2012 so we aren't talking about a decades worth of rust.All in all, I'd say if you're working out in the open with it, where they is nothing that will impede your length from the bolt and it's not rusted on, then you'll be okay. Also if you just need to tighten things then you'll be fine also. Otherwise, spend a few more bucks and get something smaller with more power.

I bought this to do tire rotation maintenance on my car as I gotten tired of dealing with universal lug wrench and scissor jack stands. I bought an adapter for the jack stands to be powered by this tool. It works pretty well for it.Either I over tighten the lug nuts on my wheels or tool is slightly underpowered. Not sure as I never really used impact wrench before but I have watched professionals use air tools. But it does remove the lug nuts in a few seconds and spins them off without a problem. I didn't use this tool to put the lug nuts back on as I rather do that manually with the lug wrench.I didn't use the included sockets as I bought impact sockets specifically for lug nuts. From the looks of it I'd say it'll work just fine.Overall I am happy with this tool. It does make the job alot easier and faster too.There is thing I need to mention. The trigger button (forward / reverse) is very sensitive so I'd be careful of handling it when changing sockets.
