From the Manufacturer

Hitachi's WR12DM impact wrench combines the most power on the market in the smallest tool housing.

The WR12DM is equipped with a powerful motor, with a nine-percent larger core diameter, 13-percent larger stacking length, and 33-percent larger volume armature than the competition. This impact wrench delivers more than 1,330 in./lbs. of torque while weighing only 3-1/2 pounds. A convenient belt hook is built into the tool.

This review is from: Hitachi WR12DM 1,330-Inch/lbs. Impact Wrench (Tools & Home Improvement)

I work as an assembler for Wal-Mart. Having personally used the Milwalkee, Makita as well as the Hitachi (an earlier model), I can tell you that nothing works as well as this tool.

It outpowers the milwaukee by a lot. It is smaller and stronger than the Makita.

It is lightweight, heavy duty, and I love the belt clip. The only fault I have with this tool is that the batteries are not Ni-Mh. However, in my previous 12 volt Hitachi(uses the same batteries), I had no problem with memory and they would last about 2 years in heavy heavy everyday use. When I say heavy use I mean between 8-16 hours a day 6-7 days a week. We put a lot of bikes together.

Hitachi has made a lot of improvements to this model over the previous model. I still have the previous model by the way (5 years and still going strong!) The biggest improvent is the weight. They have also added an electric brake which is great. They have also changed the design of the battery it will stand up on the battery. The handle also has a cushion built into it so that it is more comfortable and better balanced. The batteries last for over an hour of heavy use. The charger that comes with the new model charges the battery faster than the old one too.

I am very impressed with this tool overall.
