Snap-On CT6850 Cordless 1/2" Drive Impact Wrench
Snap-On offers a huge selection of cordless impact wrenches to choose from which made it difficult to pick out a best one. However, I like this particular model for the combination of features it offers. The torque on this tool is lower than the ones I've already mentioned, providing 400 ft. lbs. But the bolt break-away torque is 620 ft. lbs. That's still enough for lots of work, so if you don't need the high torque of the others, you may want to consider the Snap-On for their quality reputation. This one also uses a friction ring on the anvil, rather than a ball detent. It's 7.6 pounds, measures 9.95" in overall length, and comes with Ni-Cad batteries rather than Li-Ion, so the batteries have a 2.5 Ah capacity. The kit comes with two batteries and the charger.
