The Hitachi WH18DBDL 18-Volt 3.0-Ah Cordless Brushless Lithium-Ion Impact Driver is the second in a series of revolutionary brushless Lithium-Ion cordless tools. This next-generation technology manages the tool’s motor through use of a microprocessor, resulting in ultimate efficiency. Not only does this technology remove the hassle and downtime of having to replace brushes, but it also prevents the traditional wear on the trigger switch and the armature, creating an extremely durable impact driver that is essentially maintenance-free. Powered by a 3.0-Ah Lithium-Ion slide-type battery for fade free power and 3x the total battery life of traditional batteries, this impact driver provides professional grade power with 1,420-pounds of turning torque, 3,200-BPM and up to 2,600-RPM. The 4-stage electronic speed switch provides precision and control. This tool has a 1/2-Inch hex chuck for quick and simple bit replacements with limited and continuous impact modes for ultimate control when driving small fasteners or driving into soft material. The optical trigger switch provides a more responsive variable speed actuation and wear resistant trigger assembly. This tool also features a metal belt hook, digital control panel, LED light, and a battery indicator. Ergonomic and lightweight at just 3.7-pounds, the WH18DBDL reduces fatigue during extended or elevated use and truly stands alone against other impact drivers. (2) batteries, a charger and carrying case are also included. The Hitachi WH18DBDL 18-Volt 3.0-Ah Cordless Brushless Lithium-Ion Impact Driver comes with a lifetime tool warranty, 2-year battery warranty and a 1-year charger warranty. Hitachi continues the tradition of innovation and engineering with new features in addition to classic quality.
