Love my air tools - hate dealing with the hose.
The hose is an issue but not too bad if it is a rubber hose. The vinyl hosts are miserable. Given the price of the battery powered or 12 volt powered guns, I will pull a hose for $125.
As far as air impact wrenches vs electric goes, I will also pull a hose. I had an electric impact gun. I gave it away when I got a real air compressor and air impact. There are a lot of junk air impacts out there. The Ingersoll 231 is a good gun for the money. The Titanium is one kick-*** gun. This is the gun you want for Xmas. The $800 1/2" Industrial gun is the best but it has almost too much torque. I have seen the output shaft break...twice.
Speaking of air tools, there is one air drill that I truly love. It is also the one drill I grab when I need to drill a precise hole. It is a Skil 3/8" air drill that was made some 20-30 years ago. It truly is a variable speed air drill that is extreme low speed capable. I was lucky enough to find a second one for my son on Ebay a year or so ago.
The reason it works so well at low speeds is that there are two tiny coil springs behind each vane in the air motor. This holds the vanes against the cylinder at all times. The lesser air drills rely on centrifugal force to hold the vanes against the cylinder wall.
Ergonomically it is nearly perfect. Balance and comfort is uncanny when equipped with a Jacobs 0-3/8" chuck. Don't judge balance until an air hose is connected.
My advice is if you ever see one, buy it. But be very careful not to lose the vane springs when taking it apart. Skil has no record of ever having made it so parts are non-existent.
The front bearing is a double row ball bearing.
Here are a couple of pictures.
I have not tried the IR 7802 drill. It may also perform as well at low speeds but it certainly does not look as comfortable.
