Tungaloy Corporation and NTK Cutting Tools plan to merge on January 1, 2027, subject to legal and regulatory requirements. The integrated business will operate under the Tungaloy corporate name. NTK Cutting Tools will remain a dedicated division and brand. The merger combines Tungaloy’s broad cutting tool portfolio with NTK’s expertise in ceramic tooling and miniature products.
The planned merger also includes investment in a new NTK Cutting Tools headquarters and manufacturing facility in the Nagoya area of Japan. The facility is intended to expand production capacity and introduce advanced manufacturing technologies. It will also bring manufacturing, engineering, marketing and corporate functions into a modern working environment. For customers and distribution partners, the companies expect the integration to expand access to technologies, application expertise and industry knowledge.
Complementary tool technologies
Tungaloy and NTK Cutting Tools describe the merger as a combination of complementary capabilities. It is not intended to absorb the NTK brand. After completion, NTK Cutting Tools will continue as a dedicated division within Tungaloy. It will retain its established name in the cutting tool market. Tungaloy contributes a broad cutting tool portfolio, along with expertise in grade development and product innovation. The company serves industries including automotive, aerospace, energy and general engineering.
Founded in 1934 as Japan’s pioneer in cemented carbide, Tungaloy is part of the IMC Group. It combines materials technology, product development and engineering support. NTK Cutting Tools brings specialist expertise in ceramic cutting tool technology and miniature product lines. Ceramic tooling can require specific application knowledge. This is particularly relevant when selecting suitable processes and operating conditions. Therefore, retaining NTK as a dedicated division indicates that this specialised technology and its related expertise will remain identifiable within the larger organisation.
New Nagoya facility supports capacity plans
Alongside the organisational integration, the companies have finalised plans for a new NTK Cutting Tools headquarters and manufacturing site in the Nagoya area. The multimillion investment is intended to increase production capacity and introduce advanced manufacturing technology. The new site will also provide facilities for engineering, marketing and corporate functions. These will operate alongside manufacturing activities. Bringing these functions together can support closer links between production, technical development and market-facing teams. For a tool manufacturer with a specialist product range, this connection is relevant when application requirements must be translated into manufacturing and engineering decisions.
The announcement does not provide details on the facility’s size, timing or technical specifications. However, it places the investment alongside the planned merger. This links expanded manufacturing capability with the wider integration of Tungaloy and NTK Cutting Tools. The companies state that the combined organisation will offer manufacturers and distribution partners a broader range of technologies and application support worldwide.
