发明名称 Cemented carbide cutting insert having integral structure for securing the insert in a holder
摘要 A cutting insert intended for chip removing machining includes a body forming at least one cutting edge, a securing structure such as a helical thread disposed at one side of the body, and a key grip such as a profiled recess disposed at an opposite side. The insert is formed of injection molded cemented carbide such that the body, the securing structure, and the key grip are all integral with one another. The insert is secured in a holder by rotating the insert using a key which engages the key grip, whereupon the securing structure engages a complementary securing structure on the holder to pull the insert body against the holder.
