Hitachi12 Volt Li-Ion Peak Impact Driver - WH10DFL2
Hitachi’s light-duty impact driver is the lightest on our list; weighing in at only 2.2 pounds. This upgraded unit provides 955 in/lbs of torque, and up to 3,200 BPM of impact power at 2,700 RPM. All three of those numbers are up from the preceding model, without increasing the tool's weight. Perhaps the best thing about this tool is that it comes with Hitachi’s lifetime Li-Ion tool warranty. That means you won’t have to worry about any problems with the tool. Like the DeWalt, the battery pack is part of Hitachi’s battery system, rather than an in-the-handle one. This also makes it possible to stand the tool on the battery base between using it. An LED light helps you see your work and they've even added a belt hook, the one thing that seemed to be missing from the previous model.
