Covered by Hitachi's Lifetime Lithium Ion Tool Warranty, the WH18DBDL2 Triple Hammer Impact Driver is part of Hitachi's 18V Brushless Lithium Ion Cordless Tool lineup and in a class of its own. This revolutionary professional impact incorporates a third anvil for ultimate torque, less vibration and faster tightening speed. Equipped with four different speed settings, the triple hammer impact driver can conveniently tackle a wide variety of applications with just one tool in hand. It is powered by Hitachi's compact 3.0 Ah battery that delivers the same capacity as a traditional 18V 3.0 Ah lithium ion battery, but in a significantly smaller footprint with a lighter weight. Hitachi's signature ergonomic tool body design makes it extremely well-balanced and comfortable for extended use.
