Dijet
What is Dijet?
Dijet Industrial Co., Ltd. is a Japanese cutting tool manufacturer specializing in carbide machining tools. The company was founded in 1938 and has since operated as part of the international machine shop industry, developing tools especially for demanding machining applications. Dijet is known as a manufacturer who oversees the entire carbide tool manufacturing process, from raw materials to finished cutting tools.
Dijet’s History and Position in the Machine Shop Industry
Dijet started operations as an internal unit within Kobayashi Industrial Co., Ltd., and adopted the name Dijet in 1954. The company has long been involved in the development of carbide technology and was among the first manufacturers to introduce cermet tools for machining applications. With over 80 years of history, Dijet has become a well-established presence among machine shops and machining centers around the world.
In 1997, all of Dijet’s domestic offices in Japan received ISO 9001 certification, a reflection of systematic quality management and production consistency. The majority of Dijet’s new products are still made in Japan, ensuring consistent quality and tight control of manufacturing processes.
Dijet’s Integrated Manufacturing Processes
One of Dijet’s key features is its integrated production model. The company manufactures its carbide tools from start to finish in-house, covering processes such as raw material granulation, sintering, tool grinding, and coating. This enables precise optimization of tool characteristics—such as wear resistance, chip formation, and edge geometry—for a wide range of machining scenarios.
The composition, grain size, and coatings of the carbide are selected based on the intended application, which is particularly important in demanding machining environments like processing hard steels, aluminum, and special alloys.
Dijet in Mold & Tool Machining
Dijet is especially renowned for its solutions targeted at mold and tool machining. The company has developed several tool series optimized for finishing and pre-finishing work where precision and surface quality are critical. For example, the Mirror Series tools are designed to achieve extremely fine surface roughness during the finishing stage, which is vital in mold and tool manufacturing.
Tool solutions designed for 5-axis machining support high feed rates and stable machining paths, helping to reduce overall machining time and improve process control with complex parts.
Dijet’s Tools in Different Industries
Although Dijet has a strong reputation as a mold machining specialist, its cutting tools are also widely used in other areas of the machine shop industry. The tools are utilized in applications such as automotive, aerospace, and other sectors where precise and repeatable CNC machining is required. The range includes drills, milling tools, indexable insert tools, as well as special tools for hard-to-machine materials.
Summary
Dijet is a long-standing Japanese manufacturer of cutting tools specializing in carbide machining tools. The company’s strengths include integrated manufacturing processes, decades of experience, and specialized expertise in mold and tool machining. Dijet’s tools are designed to meet the demands of machine shops and machining centers, delivering precision, durability, and process reliability.
