Chordless impact wrenches

[pekingduck]

I use Ridgid brand from Home Depot as they offer a lifetime warranty/service contract that no other brand offers.

I use them too, and they're pretty good.  I heated up the drill pretty hot this evening drilling 1/2" holes in steel plate.  Still works though.

Surprisingly, my favorite tool in the series is the tire inflator...to be able to walk around to all the cars, trailers, motorcycles, etc. and quickly top them off is so convenient compared to getting out a heavy air compressor, hooking up the hose, fittings, extension cord, lugging it around, draining the moisture when finished, etc.

Back to the impact wrench question, I would buy whichever cordless model matches the cordless tools you already have, assuming it gets good reviews.  And I would use the highest capacity battery you have.

My Ryobi tire inflator is a really handy, useful tool.  You still need a plug-in compressor for big jobs, but it replaced my small compressor on wheels.
