This study deals with shoulder cutting phenomena in micro-end-milling of hardened die steels and investigates effects of gash tools and left helix flute tools. We revealed that cutting phenomena become unstable because the end cutting edge is damaged early in shoulder cutting. Therefore, we experimentally prepared a gash tool and left helix flute tool to perform complete processing by improving the strength of the end cutting edge. Cutting experiments were carried out while measuring cutting force and observing cutting phenomena, end cutting edge and machined surface with SEM. As a result, we determined the effects of such tools on fundamental phenomena in shoulder cutting with a micro-end-mill.
