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. 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. 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. there is no electric brake on the tool. The best thing about this impact is the variable speed dial. It really puts you in control of the torque output. I bought this tool so I could work on my car. 1.
2. i only have 2 gripes about this tool. 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. I recommendd getting a 16 foot extension cord cuz the 10 foot cord supplied with it is not long enough. This tool does the job for me. So instead of the impact stopping when the fastener spins off it keeps spinning.
So far i haven't found anything it can't loosen on my car. it's pretty much maintenance free too. 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. 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.
(assuming you already have impact sockets)I'd like to see how it holds up in a busy shop environment, it'd be interesting to see if it could take the abuse. I'd recommend this to anyone who doesn't own an air compressor but wants the ability to use an impact to speed up their work.
The bolts holding the lower rear arms were big and beefy. This Milwaukee 1/2" impact helped my brother and I remove lower control arms off a 1998 Honda Civic.
I was satisfied with the torque output this small electric motor can put out. I would of cried having to do it on the floor without the help of this gun.
It is kind of bulky in some tighter areas but you could always buy yourself a smaller 3/8" cordless impact for small bolts or screws. Get a long heavy gauge extension cord and you're set.
So far this one has held up great for me.
Building an oak log home, I had been using a pneumatic wrench to drive the 2 1/2" X 5/8 lag bolts that hold the beams to the logs supporting the second level. This drives the bolts about twice as fast as the air gun, very easy to handle. I forsee lots of use in this project and others.
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. The torque spec on these nuts is 174-224 ftlbs, and the wrench spun them off with ease. 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. This doesn't hurt anything when you have the socket on a nut, but it bugs me. I also wish that the tool included a little T-handled punch to press the detent pin when taking off a socket. There's a couple of minor annoyances. Obviously it removed the lug nuts easily as well.
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. I used this wrench to remove the front wheel axle nuts on my car, so I could replace the CV half shafts. 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. It could be the cheap impact sockets I'm using, or maybe all impact wrenches do this. 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. 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.
It hammered for less than a second and the nuts were off. 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. 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. 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. It seems to be solidly built, so I expect it to hold up well.
It works GREAT. Arrived on time from shipping. It really puts in lag bolts without breaking the bolt. It's worth buying.MILWAUKEE TOOLS are the greatest.
