Abstract
A split-die press tool for forming, by compressing a powder, a green body for a double-sided and double positive cutting insert for metal cutting. The tool includes a die with at least two die sections having a punch tunnel formed therebetween, an upper punch unit and a lower punch unit. When the lower punch unit is in a distal position a front end periphery of the lower punch unit is at a first expansion level corresponding to a maximal downward vertical decompression expansion of the green body to be formed. The punch tunnel has a first side surface portion on at least one of the die sections that has a vertical extension downward from the first pressing level to the first expansion level and is inclined downward and away from the pressing axis by an angle β of at least the angle α of an adjacent inclined lower surface of the green body.
