History of Innovation
Since 1948 Hitachi Koki Company Ltd. has been an independent member of the broadly diverse Hitachi group. Hitachi Koki's relationship with its parent company brings important benefits to customers. These benefits include immediate access to the latest advancements in metallurgy, motor design and electronics - often long before these technologies appear in other manufacturers' product. An example of this benefit is the ultra-high speed motor developed by Hitachi for use in medical centrifuges. Hitachi Koki uses the same armature balancing technology in developing electric motors for its line of power tools.
In 1980 Hitachi Power Tools U.S.A. was created to market the line of tools in the United States. During the 80s, Hitachi Power Tools U.S.A. built its reputation for quality on the success of its pneumatic framing nailer and sliding compound miter saws.
Time and resources have always been dedicated to research and development of innovative and durable power tools. Such dedication to product development has led to a number of firsts and countless improvements in power tool technology. Hitachi pioneered the Sliding Compound Miter Saw, Cordless Impact Driver, Collated Automatic Screw Driver, Pneumatic Concrete Nailer, Cordless Screw Driver, Metal Stud Cutter, Portable Rebar Cutter/Bender, 10 minute rapid charger, 2.0, 2.2, and 2.4 Ah Ni-Cad batteries, 3.0 Ni-MH batteries, and the use of rare earth magnet motors in cordless tools. In addition, Hitachi is a world leader in metal casting technology, metallurgical science and plastics technology. This expertise, coupled with Hitachi Koki’s High Speed Motor Technology, Precision Processing and Electronic Control, allow Hitachi Koki to produce lighter, faster, and more durable power tools for the professional.
Hitachi Koki manufactures more than 1000 models of electric power tools, focusing on compact/high out-put motor technology. The company has obtained recognition under the ISO 9000 series international standards for quality assurance. Hitachi Koki also received ISO 14001 certification for environmentally sound management.
In 1994 Hitachi Power Tools U.S.A. was renamed Hitachi Koki U.S.A. to denote the addition of manufacturing to the United States. Hitachi Koki U.S.A. continues to forge aggressively into the future developing new technologies that benefit the longevity and performance of the Hitachi power tool line. Recently Hitachi purchased Tanaka Power Equipment as a brand within the Hitachi Power Tools group. Tanaka's innovative product line provides landscapers, construction professionals, property managers, and utility professionals with two-stroke commercial grade outdoor power equipment solutions. The Tanaka brand offers a complete suite of grass trimmers, brush cutters, multi-task tools, chainsaws, blowers, hedge trimmers, edgers, augers, gas powered drills, water pumps and a complete mix of accessories.
Hitachi never stops improving and developing technology to make Hitachi Power Tools superior in the industry.
