Kobalt Model #6904, 1/2" Corded Impact Wrench
Kobalt tools are a brand of Lowe's Home Improvement Centers, manufactured to compete with Craftsman. I have a few of their tools and from what I've seen of them, they are well built, rugged tools that are intended to last. We can see that from the five year "hassle-free" guarantee that they put on this tool. At 350 ft. lbs. of torque, this one ties for first place in overall power. The 8 amp motor gives you plenty to work with, running at 2100 RPM and 2700 IPM of impact power. The trigger is a toggle switch, making it easy to change directions, when you need to. It also includes a live wire indicator for safety and comes with 7 deep well impact sockets. Sockets are held in place by a "bull-nose" friction ring.
