A must-have power tool for professionals is Hitachi's WH 14DBL cordless impact driver, which conserves energy by using a newly developed e-motor (brushless motor)*. The power tool also features a long service life, using lightweight Lithium-Ion Batteries with a unique safety design. These innovations help reduce the burden on the environment.

The number of home centers offering tools and materials designed for professional use has recently increased. The various techniques, know-how and common sense that is standard in professional industries may surprise consumers once they experiment with such products that they may or may not have had experience with in the past. When introduced to these easy-to-use products, consumers are typically left with the desire to possess one of their own. One tool that is envied by such everyday users is Hitachi's WH 14DBL cordless impact driver.
Unlike a standard power drill that uses rotation only to tighten screws, the impact driver also exerts a force along the axis of rotation to drive the screw in as it is tightened. The rechargeable cordless design gives the tool superlative maneuverability. Having earned the high regard of professional construction and electrical tradespeople, the cordless impact driver truly is a must-have power tool.
Advances in cordless technology allow you to use power tools anywhere. Hitachi has placed a particular emphasis on improving operating time and battery life while also making the tool smaller and lighter, based on feedback from professional users. A longer operating time per battery charge is ideal. The WH 14DBL cordless impact driver features a newly developed e-motor (brushless motor) with improved efficiency due to lower electrical losses. The result is approximately a 30% more amount of work per battery charge than previous models*. This represents a saving in annual power consumption of about 23%*. In fact, the cordless impact driver not only provides improved performance, it also helps reduce the burden on the environment.

Since power tools are inevitably used in harsh conditions, if the battery is stressed by excessive over-discharging or over-charging, this affects the safety of the battery as well as how long it will last. For this reason, when switching over to Lithium-Ion Batteries, Hitachi chose to incorporate a proprietary optimized charging system and multi-function battery protection circuit that monitors the current, voltage, and other parameters.
The benefits are two-fold: Improved battery safety and also successfully prolongs the battery life
Combined with the e-motor, these features extend the amount of work that can be performed before the battery reaches the end of its life by about 1.7 times (*1). In addition to the cost savings, supplying such long-lasting products also helps reduce the burden on the environment. Hitachi is also actively involved in recycling used batteries as one of its measures for protecting the environment.
The Hitachi Group views the WH 14DBL/WH 14DBAL Cordless Impact Driver Series as one of the ways we can achieve our Environmental Vision 2025, with a goal of helping to reduce annual CO2 emissions by 100 million tons by 2025 through our products and services.
