Yeah, the fuel models seems to be real good. The guys at work like em alot, so much so I am tempted to buy one myself, but I am still a bit old school, and I find the cordless models heavy.
After a long day at work, I tend to go with shop air but mind you, I have an impact in my hand all day, and like I said, Im still old school, so my advice probably;y doesn't count here, all I can say is the fuel set is winner but you may also want to look at dewalt, they make a good set also. I own a kit in 12volt version and it gets alot of abuse.
I would be on fence if I had to invest again, fuel or dewalt XR.
Have a good day, I am off to work, here is a link to that XR model. 319$ with battery and charger vs the fuel version which for some strange reason never comes with a battery, so that kind of sucks and would probably tilt my way and also the dewalt is lighter, but on the other hands, the fuel models seem almost indestructible. So, as you can see, I am not helping,
The DEWALT DCF899M1 Cordless 1/2 in. Impact Wrench is ideal for most fastening applications. Powered by a DEWALT brushless motor, this cordless impact wrench features up to 700 ft. lbs. of max torque and 1200 ft. lbs. of max breakaway torque. This power wrench can make up to 1,900 rotations and...
I gotta ask... how do the "fuel" tools work? Do they ignite the fuel (in brief spurts) to drive a mechanism/engine, or do they rely strictly on the pressure of the fuel in its can? Either way, what is the driving mechanism for a rotating tool like an impact wrench? It is easy to visualize driving a nailer with fuel, but not-so-much for a rotary tool.
