Sumitomo Electric Industries, Ltd. (headquarters: Chuo-ku, Osaka, President: Osamu Inoue, hereafter "our company") has expanded and launched Coated SUMIBORONTM BNC2105/BNC2115/BNC2125 inserts for hardened steel metal machining for sale as of November 2024.

Finishing of high-hardness steel for automotive parts and bearing steel for bearing components calls for excellent dimensional tolerance and surface roughness. Further, demands for increased productivity are on the rise in order to support multi-model, multi-quantity production as parts machining diversifies. In order to respond to these needs, our company has launched Coated SUMIBORONTM BNC2105/BNC2115/BNC2125 for hardened steel machining. To support more machining shops and parts specifications, we have expanded the lineup to include 1.2mm corner radius inserts.
