For the guy who only buys the best, this one is for you. The Ingersoll Rand IR2135QXPA is one of the best 1/2" impact wrenches on the market. Not only is it lightweight, coming in at 4 lbs, but it is also quiet and compact. Despite these creature comforts, it features a whopping 1100 ft.lbs of nut-busting torque.
If you break down in baja, this is the tool you'll be glad you packed.
