This study aims to investigate the influence on the basic cutting performances when changed the tool geometries and the cutting conditions in high speed end milling. The hardened steel (SKD11 (HRC58, 60)) and (Ti, Al)N coated carbide square end mill were used in this experiment, and tool wear, finished surface roughness and cutting force were researched by side cutting under the dry cutting conditions. From the obtained results, the high speed cutting at 565 m/min was possible and it was advantageous in the points of tool wear, chatter and finished surface roughness to increase the feed rate, and the possibility of high efficient end milling was confirmed. In addition, when the end mill of high helix angle was used, a further improvement was possible.
