Affiliated Company of the Month: Tokai Sumiden Precision Co., Ltd.

Mt. Gozaisho

The predecessor of this company, Tokai Seimitsu Ltd., was established in April 1984 as a wholly-owned subsidiary of Sumitomo Electric Industries, Ltd. for the production of its cemented carbide tool "IGETALLOY". To alleviate the overcrowding of its factory floor, in August of the following year the company moved its head office and factory from Yokkaichi City to "sun-drenched, verdant" Komono Town, situated at the foot of the Suzuka Mountains, with Yunoyama Hot Springs. In July 2011, the company changed its name to Tokai Sumiden Precision Co., Ltd. to further enhance its cooperation with Sumitomo Electric.

"Multi-Drill" Series Ensures Satisfactory Product Quality

The company produces IGETALLOY cemented carbide products, which are originally developed by the Sumitomo Electric Group. Sumitomo Electric launched the research and development of cemented carbide in 1927, and after tireless research and improvement, succeeded in the manufacture and commercialization of the products.

Cemented carbide is the second hardest material after diamond, and is as tough as steel. Using this material, we produce the Multi-Drill series products that are widely used for drilling holes in steel. Having a comprehensive production line from development and design to manufacture, the company serves as the mother factory of these drill products. The company has also proactively invested in facilities to save labor and automate the production process, thereby producing high-quality products at high efficiency.

Since "Multi-Drill" series products ensure high-efficiency, high-accuracy and low-cost drilling with a long tool life, they are widely used in making automobile, aircraft, construction equipment and various other industrial parts. The company's technological capabilities have earned the high trust of both domestic and international users.
