Nothing shortens the lifespan of a tool faster than vibration. Hitachi addressed this common problem by developing a patented technology called IDI (Internal Double Insulation). This technology is incorporated to ensure that Hitachi Power Tools outlast the competition and exceed expectations.

In the world of power tools today, it is
common to find companies that produce tools using similar materials and
processes in order to come to market quickly and most cost effectively.
As a result, you find similar tool offerings with very little
distinction aside from tool color and brand recognition.
the case with most companies. Hitachi is not most companies. Tracing
back to our roots, you learn that Hitachi’s founder Namihei Odaira
passionately believed that he would create a company that would make
some of the highest quality products in the world and also contribute to
the further advancement of society by autonomously developing
technology. This belief has persisted throughout decades at Hitachi. It
is what inspires us to continually make improvements to our tools that
will benefit their longevity and reliability.
An example of this
technological advancement can be seen with Hitachi’s patented IDI
(Internal Double Insulation) technology. Formerly, power tools were
designed with metal bodies in order to add durability. They did just
that, however they were also extremely dangerous, often shocking users.
The common resolution in the power tool industry was to produce the
housing out of plastic, which proved much safer, but less durable and
less resistant to vibration. For Hitachi, that was not the appropriate
solution. We wanted to have the durability characteristic of a metal
housing, with the safety features of plastic. So IDI was born. The
technology incorporates an aggressively designed aluminum housing that
is intertwined with an injection molded inner nylon core providing the
durability of metal body tools, with the double insulation
characteristics of today’s tools with plastic housings. IDI technology
dramatically increases the tool life by combining the positive
characteristics of both metal and plastic into one tool. Vibration is
less wearing on the tool and overall safety and reliability are
IDI Technology is being designed into
Hitachi Power Tools. Currently, the G18MR and G23MR Grinders, DH40MR
Rotary Hammer, and a host of other power tools feature this technology.
They will outlast any competitive tool and exceed the user’s
expectations each time.
