Abstract

The hard alloy electroerosion electrode (1) in form of a rod with at least one longitudinal channel (2) is characterized by the following fact: the ratio of the difference between the maximum (9) and minimum (10) radii of the channel cross section to the maximum radius (9) is at least 0.01.
