Mitsubishi Materials Corporation
Effective April 1, 2025, Mitsubishi Materials Corporation ("MMC") renamed its global brand for cemented carbide tool products from "DIAEDGE" to "Mitsubishi Materials." Launched in 2017, DIAEDGE played a significant role in raising the company's overseas sales ratio to 80%. This rebranding aims to strengthen global competitiveness, further expand sales regions, and accelerate overall sales growth.
In conjunction with this brand change, the trade names of four group companies within the MMC Metalworking Solutions business, which manufacture cemented carbide tools, were changed effective July 1, 2025. This change applied to the manufacturing and sales subsidiary in Japan, the manufacturing subsidiary in Thailand, and the sales subsidiaries in Mexico and Brazil.
In recent years, the digitalization and automation of the manufacturing industry have progressed in the global market, leading to a diversification of customer needs. Furthermore, as the demand for environmental considerations grows, providing sustainable products and services has become key to competitiveness. In response to these changes in the external environment, MMC needs to secure greater competitiveness by revamping its brand.
MMC Group has established Our Commitment as "For people, society, and the earth, circulating resources for a sustainable future." As a leading company in cemented carbide tools, we will support manufacturing around the world and work to realize Our Commitment.
From July 1, 2025, the trade names of group companies related to cemented carbide tool products were changed as follows:
