Combining high torque with 1,450 rpm and 2,450 ipm, the 0779 provides the power, speed and run-time to drive larger lags, drill bigger holes, and remove larger nuts. The powerful Milwaukee 28V motor makes breaking loose stuck nuts a breeze. The heavy-duty magnesium mechanism housing provides extreme job-site durability. The 0779 comes equipped with comfortable non-slip, soft-grip surfaces that reduce vibration and fatigue. The forward/reverse shuttle is conveniently located above the variable speed switch for fast, easy access. Designed for heavy-duty use, whether driving large lag screws, anchors and bolts, drilling large holes, or removing lug nuts, the 0779 provides the power, comfort and run-time to finish the job. A heavy-duty steel ring (included) can be attached for convenient tethering when working high overhead or for raising/lowering the tool when working from a ladder or utility pole.

Potent Wrench
This is one cool tool, No longer do I need to break out the compressor and hoses, to have some serious driving power. 3/8 and 1/2 inch lags, no problem. Even does lug nuts.
Bigger bolts do shorten run time, but for me that is not much of a problem. I don't have to drive over 20 large lags a a time. Easily does all the lug nuts for a tire rotation.
This is a heavy tool, if I had to work over head much, I would go pneumatic.
