Abstract

A method of making a cutting insert using powder metallurgical methods including using a press with a main pressing direction and a press tool setup with a die, a male core rod, a female core rod, a bottom punch, a top punch and a feed shoe. The insert has a noncylindrical hole perpendicular to the main pressing direction, herein referred to as a cross-hole. A cross-hole with increased dimensional accuracy is obtained if the powder also is compacted by the two core rods.
