DIJET introduced cemented carbide to industries and has worked for innovation of carbide tools and the evolution of machining with our own technology since establishment in 1938. DIJET brought innovative technologies into the worldwide market, like the first practical use for CERMET (which is quite common now a day) based on powder metallurgy cultivated on manufacturing of carbide, development of ball nose end mills and drills with HOSOI geometry on cutting edge for cutting tools, and end mills with helical cutting edges. Even now, DIJET continues to develop its own technology like mono-block diamond products, gear-forming dies with carbide, and carbide material with saving rare metals, marketing domestically, and all over the world.
