In recent years, processing and cutting small precision parts for automotives and information equipments has demanded the high quality and long-life tools at ever greater levels.
To respond to user demands for higher quality materials for tools, avoiding processing ability loss and crack, Kyocera has developed a strong new material and will start releasing two series that improves resistance to damage and wear.

Features of New Materials
Kyocera has successfully developed long-life micro grain carbide substrate to improved hardness and strength while enhancing rigidity by improving components and the mixing methods from conventional tools. By combining Titanium Carbonitride (TiCN) thin film PVD coating* suitable for micro grain carbide substrate, specially developed by Kyocera, these products offer stable and twice longer life, comparing conventional one. In addition to its existing tool for processing steels, PR930, Kyocera will introduce PR1025 for medium to low speed, interrupted processing of steels and PR1005 for medium to high speed, continuous processing of free cutting steels. These new products realize to achieve high productivity for processing every kind of steel, from general to free cutting steels.

*PVD coating: Physical Vapor Deposition. A method of coating the substrate materials by producing a chemical response using electricity or thermal energy.

Product Features
PR 1025 realizes stable cutting, employing a special PVD coating featuring anti-oxidation performance and wear resistance, as well as a stronger carbide substrate that improves the constituent materials.
It helps reduce costs and improve the productivity with the extended life span, twice as long as conventional one.

Thanks to the high sintering technology, the product provides low reactivity and strength, comparing with conventional products.
The product employs a sharp blade shape, suitable for free cutting steels, and PVD coating for anti-oxidation performance and wear resistance to achieve high quality processing and cutting of materials, and to double tool life improves user productivity and reduces costs.
