FIELD: technological processes.
SUBSTANCE: group of inventions relates to manufacture of a cutting insert having a through-hole which extends in a direction which is non-parallel to the main pressing direction. Method comprises moving first and second punches within a die cavity toward each other along a first pressing axis to compact a powder around a core rod into a cutting insert green, wherein, during at least a portion of the compaction step, the core rod is turned a predetermined angle in alternating direction around its longitudinal axis. Arrangement for manufacturing a cutting insert is also provided.
EFFECT: manufacture of the cutting insert with the dimensional accuracy is provided.
