Hitachi Power Tools introduces the cordless 18-volt, 1.5Ah impact driver, the WH18DFL, which combines the high torque of automotive wrenches with the precision of traditional driver drills. The ¼-inch hex impact driver includes an electric brake and is designed for fastening, driving and drilling applications. The 1.5Ah lithium ion battery reduces the tool weight, which is designed to lessen user fatigue and improve manageability in awkward or overhead applications. Weighing 3.3 pounds, this impact driver features a two-piece magnet motor with a tightening torque of 1,150 inch-pounds.
