[Company strength]
We utilize diamond, which is the hardest mineral on earth, to develop and manufacture ideal tools for processing various materials. We have focused on improving our technology since our company was established in 1932, and are proud to be counted among the world’s best. We try to improve customer satisfaction in technology development and production, and provide the most suitable solutions through consulting sales to identify customers’ needs, not just manufacturing and selling tools. We contribute to society by supplying tools and services for creating state-of-the-art products, with the challenging spirit of “Doing what no one else has tried”. In particular, our technology for manufacturing single-crystal diamond bits and fine porous resinoid bonded diamond grindstones having excellent cutting-edge counter precision is the best in Japan.

[Business description]
Our company manufactures, sells and reproduces made-to-order diamond/CBN tools in general; sells machine tools to manufacturers of electric/electronic and precision equipment, semiconductors, transport plane parts and other products; and constantly offers tools for cutting, shaving, polishing and drilling with higher precision, quality and speed, with industry-leading technologies.
