Bringing solutions since 1929

The two predecessor companies, Shibaura Engineering Works Co., Ltd. and Tokyo Electric Company, succeeded in developing cemented carbide for the first time in Japan. The product was sold on the market as “Tungaloy”.

Building a bright future

Since its inception in 1929 when it was Japan’s first company to develop cemented carbide, Tungaloy has had a long history of excellence in the development of materials for metal cutting tools and innovative industrial products.

The diverse range of products, including metal cutting tools, such as indexable inserts and steel products, wear resistant tools, civil engineering tools, and friction materials, are all based upon Tungaloy’s expertise in powder metallurgy.

Research & Development

Since 1929, Tungaloy has been the pioneer in materials research and the development of cemented carbides.

Tungaloy develops cutting-edge technologies by taking advantage of the latest techniques and equipment as well as its close relationship with customers worldwide in all industry sectors.

As the market leader in the development of powder metallurgy and innovative coating technology for high-quality cutting tools, we have the experience, expertise, and the latest equipment to ensure we remain the benchmark in the industry.

In 1997, Tungaloy became the first carbide cutting tool manufacturer in Japan to acquire ISO14001 certification, which is an international standard of environmental management. The implementation of the environmental standards and efforts in reducing carbon dioxide emission demonstrate our commitment to building a green future.
