I have 2 but I will not say brand name as it has no reason to be mentioned except they are both the same brand. One is a 110 volt corded rated at 240 ft lbs on box when bought and second is a 18 volt cordless that was rated on box at 360 ft lbs of torque. If ft lbs rating is correct why will the one with 2/3 the amount of the other easily take off tight rusted nuts that the one with higher rating will not touch? The corded model weighs quite a bit more than the battery one. And yes I did try different fully charged batteries. The battery one is just easier to handle with the less weight and no cord to mess with while tearing apart the hay rake to rebuild. And I can take it with me in the truck. I have has air powered previously but do not have the air avaible to run one where I need it but I can lay put an extension cord for where I am at.

Despite the torque ratings a corded power tool will always win. More power. Microscopic play in the sockets or extensions can easily absorb most of the torque.

Manufacturers have a way of playing with those numbers just like they do with hp. We call it lying but they don't.

I can tell you if you want a battery one that will work buy a Milwaukee fuel 18v and a 5.0 battery. They are expensive. The only drawback I've found is you have to be carefull it you use it for tightening as they have way too much power for that.

I would agree, playing with the numbers.

They have a new one coming out next month that is slightly smaller with even more torque. I think 1100 ft-lb forward 1400 reverse. Dewalt also has one right up there. Some guys use them on heavy truck lug nuts.

I have the 20v DeWalt "Brushless" 1/2 impact. It is a monster. I think it claims 800 or 850 ft/lbs. I don't know what It actually puts out, but if it won't break a nut loose, I know I need to get a very long cheater pipe and some pb-blaster to get it loose.

Pretty sure the Snap-On or Milwaukee are just as good (or better). The brushless 20v is a huge step up over the older 18v impact that I've abused for years. It is one of my favorite and handiest tools.

Don't forget that if the torque goes over a limit set by OSHA you need to be strapped into a harness and tethered and have an assistant standing by watching you :wink:

Check the rating closely. I have a good Dewalt 20V impact that is rated at 1400. But that is inch pounds, not foot pounds. Still, very handy tool and it gets used a lot.

My Milwaukee m18 1/2" impact is the strongest impact up to 3/4" I've ever used. I have 2 snap on 1/2" air impacts and the Milwaukee has way more power. As said, if it won't break a nut loose you will need 3'+ of cheater to get it. I also just bought their 3/8 drive m18 impact and like it even better. Has less, but still awesome power and is a lot lighter and easier to use. Wouldn't want to go back to not having either. I also just added their m18 4" grinder to my tools but haven't had a chance to use it yet. My next tool will be their m12 ratchet.

Bought a Rockwell 1/2" air impact in '75. It looks like the generic 1/2" tool, but has way more power.

It'll remove the 38mm axle nuts and 38mm flywheel nut on air cooled VW's. Those are torqued to 238 pound feet.

I've tried other 1/2" air impacts and 3/4" that wouldn't do that.

The battery impacts are pretty cool, real handy.
