From the Manufacturer

This impact wrench features a quik-lok cord, pin-detent system to securely retain sockets or adapters, and a variable speed reversing switch for added control in drilling applications or driving lag-bolts. Delivering 300-foot-pounds of torque and weighing only 6-pounds, this tool has a great power to weight ratio. The powerful 7.0 amp motor drives a unique impact mechanism at 1800 RPM (no load). The ergonomically shaped handle with a soft cushioned grip provides a well-balanced and controllable feel to the tool. The special mechanism achieves desired installation torque faster and loosens rusted or fretted bolts in less time. Includes the tool only.

I used this wrench to remove the front wheel axle nuts on my car, so I could replace the CV half shafts. The torque spec on these nuts is 174-224 ftlbs, and the wrench spun them off with ease. It hammered for less than a second and the nuts were off. Obviously it removed the lug nuts easily as well. There's a couple of minor annoyances. The forward/reverse switch is backwards from every drill I've used - you move it to the right to loosen, left to tighten. This isn't hard to get used to, but it also doesn't have enough resistance to being moved. A couple of times I bumped the switch from right to left without realizing it, and hammered the lug nut for about a second before I realized I was tightening. If you're right-handed, it's easy to bump the switch from right to left while you're moving your hand to drop a nut out of the socket. It would be safer for right-handed people if left was loosen. I learned to check the position of the switch before every use, and be careful to put my index finger low on the trigger, away from the forward/reverse switch. The other annoyance is that the shank doesn't seem to be quite big enough, so a deep socket precesses noticeably when you pull the trigger. This doesn't hurt anything when you have the socket on a nut, but it bugs me. It could be the cheap impact sockets I'm using, or maybe all impact wrenches do this. I also wish that the tool included a little T-handled punch to press the detent pin when taking off a socket. I use a 6mm hex key.

I don't use it to tighten - there's no reliable way to know what torque you'll wind up with. I turn it to the lowest speed setting and spin the lug nuts on until they're snug, then use a torque wrench to tighten them to spec. The manual says to practice until you can estimate the torque from the duration of hammering, but I can't see how this would be reliable. The ability to specify the torque would be nice, but I've never see an impact wrench that has that feature.

I'm happy with the tool and recommend it. I've had it only a week, and I've only done one job with it, so I can't say how reliable it is. It seems to be solidly built, so I expect it to hold up well.

5.0 out of 5 stars You can't go wrong buying this impact wrench, June 28, 2009

I bought this tool so I could work on my car. i don't have an air compressor nor did i want to invest in the money to buy one and all the accesories you have to buy with it like air hoses, air tool oil, etc. This tool does the job for me. The best thing about this impact is the variable speed dial. It really puts you in control of the torque output. It's got 12 settings (if you count the lowest setting as 1) and I only need to put it on level 5 or 6 to rip off my lug nuts at 76 ft lbs. So far i haven't found anything it can't loosen on my car. I recommendd getting a 16 foot extension cord cuz the 10 foot cord supplied with it is not long enough. it's pretty much maintenance free too. No oiling or greasing until the motor brushes get worn (which will take quite a while to wear out) then u just send the tool back to milwaukee and they replace the brushes and regrease it. i only have 2 gripes about this tool. 1. there is no electric brake on the tool. So instead of the impact stopping when the fastener spins off it keeps spinning. there have been several times when my lug nuts have flew off and almost hit me in the face while impacting them off, but that's why I wear safety goggles. 2. the tool is rather bulky and long, almost 12 inches long so it's not very compact and doesn't fit in tight spaces real well. Aside from those things its a damn good investment if u do your own car repair, and i got free shipping from amazon, so I'm happy with my purchase.

5.0 out of 5 stars Very Pleased, May 9, 2008

I have used the impact wrench to rotate tires on my pick up as well as remove lawn mower blades. This is my first experience with an electric impact wrench and I have been very pleasantly surprised. When purchasing this unit, I was envisioning that it would work, but not as well as some of the pneumatic wrenches that I have worked with. Again, I was taken aback by the torque and responsiveness, and am very happy with the performance. I would recommend the variable speed unit, I am glad that I spent the extra few $ for this option.
